1 # Building for Supported Renesas Boards
3 AGL supports building for several automotive
4 [Renesas](https://www.renesas.com/us/en/solutions/automotive.html) board kits.
5 Renesas is the number one supplier of vehicle control microcontrollers and
6 System on a Chip (SoC) products for the automotive industry.
8 This section provides the build and deploy steps you need to create an
9 image for the following Renesas platforms:
11 * [Renesas R-Car Starter Kit Pro Board](https://www.elinux.org/R-Car/Boards/M3SK)
12 * [Renesas R-Car Starter Kit Premier Board](https://www.elinux.org/R-Car/Boards/H3SK)
13 * [Renesas Salvator-X Board](https://www.elinux.org/R-Car/Boards/Salvator-X)
14 * [Renesas Kingfisher Infotainment Board](https://elinux.org/R-Car/Boards/Kingfisher)
16 **NOTE:** You can find similar information for the Pro and Premier board kits on the
17 [R-Car/Boards/Yocto-Gen3](https://elinux.org/R-Car/Boards/Yocto-Gen3) page.
18 The information on this page describes setup and build procedures for both these
19 Renesas development kits.
21 ## 1. Downloading Proprietary Drivers
23 Before setting up the build environment, you need to download proprietary drivers from the
24 [R-Car H3/M3 Software library and Technical document](https://www.renesas.com/us/en/solutions/automotive/rcar-download/rcar-demoboard-2.html)
27 Follow these steps to download the drivers you need:
29 1. **Determine the Files You Need:**
31 Run the ``setup_mm_packages.sh`` script as follows to
32 display the list of ZIP files containing the drivers you need.
33 Following is an example:
36 grep -rn ZIP_.= $AGL_TOP/meta-agl/meta-agl-bsp/meta-rcar-gen3/scripts/setup_mm_packages.sh
39 The script's output identifies the files you need to download from the page.
41 2. **Get Your Board Support Package (BSP) Version:**
43 Be sure to have the correct BSP version of the R-Car Starter Kit
44 based on the version of the AGL software you are using.
45 Find the appropriate download links on the
46 [R-Car H3/M3 Software library and Technical document](https://www.renesas.com/us/en/solutions/automotive/rcar-download/rcar-demoboard-2.html)
48 The file pairs are grouped according to the Yocto Project version you are
49 using with the AGL software.
50 Use the following table to map the Renesas version to your AGL software:
52 | AGL Version | Renesas version |
54 | AGL jellyfish 10.0.0 | 3.21.0 |
57 3. **Download the Files:**
59 Start the download process by clicking the download link.
60 If you do not have an account with Renesas, you will be asked to register a free account.
61 You must register and follow the "Click Through" licensing process
62 in order to download these proprietary files.
64 If needed, follow the instructions to create the free account by providing the required
66 Once the account is registered and you are logged in, you can download the files.
69 You might have to re-access the
70 [original page](https://www.renesas.com/us/en/solutions/automotive/rcar-download/rcar-demoboard-2.html)
71 that contains the download links you need after creating the account and logging in.
73 4. **Create an Environment Variable to Point to Your Download Area:**
75 Create and export an environment variable named `XDG_DOWNLOAD_DIR` that points to
76 your download directory.
80 $ export XDG_DOWNLOAD_DIR=$HOME/Downloads
83 5. **Be Sure the Files Have Rights:**
85 Be sure you have the necessary rights for the files you downloaded.
86 You can use the following command:
89 chmod a+x $XDG_DOWNLOAD_DIR/*.zip
92 6. **Check to be Sure the Files are Downloaded and Have the Correct Rights:**
94 Do a quick listing of the files to ensure they are in the download directory and
95 they have the correct access rights.
99 $ ls -l $XDG_DOWNLOAD_DIR/*.zip

104 ## 2. Getting More Software
106 1. **Get the `bmaptool`:**
108 Download this tool from the
109 [bmap-tools](https://build.opensuse.org/package/show/isv:LinuxAutomotive:AGL_Master/bmap-tools)
111 The site has pre-built packages (DEB or RPM) for the supported host
114 ## 3. Getting Your Hardware Together
116 Gather together this list of hardware items, which is not exhaustive.
117 Having these items ahead of time saves you from having to try and
118 collect hardware during development:
120 * Supported Starter Kit Gen3 board with its 5V power supply.
121 * Micro USB-A cable for serial console.
122 This cable is optional if you are using Ethernet and an SSH connection.
123 * USB 2.0 Hub. The hub is optional but makes it easy to connect multiple USB devices.
124 * Ethernet cable. The cable is optional if you are using a serial console.
125 * HDMI type D (Micro connector) cable and an associated display.
126 * 4 Gbyte minimum MicroSD Card. It is recommended that you use a class 10 type.
127 * USB touch screen device such as the GeChic 1502i/1503i. A touch screen device is optional.
129 **NOTE:** The Salvator-X Board has NDA restrictions.
130 Consequently, less documentation is available for this board both here and across the
134 ## 4. Making Sure Your Build Environment is Correct
137 "[Initializing Your Build Environment](./3_Initializing_Your_Build_Environment.md)"
138 section presented generic information for setting up your build environment
139 using the `aglsetup.sh` script.
140 If you are building an image for a supported Renesas board,
141 you need to take steps to make sure your build host is set up correctly.
143 1. **Define Your Board:**
145 Depending on your Renesas board, define and export a `MACHINE` variable as follows:
147 | Board| `MACHINE` Setting |
149 | Starter Kit Pro/M3 | `MACHINE`=m3ulcb |
150 | Starter Kit Pro/M3 + kingfisher support | `MACHINE`=m3ulcb-kf |
151 | Starter Kit Pro/M3 whithout graphic | `MACHINE`=m3ulcb-nogfx |
152 | Starter Kit Premier/H3 | `MACHINE`=h3ulcb |
153 | Starter Kit Premier/H3 + kingfisher support | `MACHINE`=h3ulcb-kf |
154 | Starter Kit Premier/H3 whithout graphic | `MACHINE`=h3ulcb-nogfx |
155 | Salvator-X | `MACHINE`=h3-salvator-x |
157 For example, the following command defines and exports the `MACHINE` variable
158 for the Starter Kit Pro/M3 Board:
161 $ export MACHINE=m3ulcb
164 2. **Run the `aglsetup.sh` Script:**
166 Use the following commands to run the AGL Setup script:
170 $ source meta-agl/scripts/aglsetup.sh -m $MACHINE -b build agl-devel agl-demo
174 Running the `aglsetup.sh` script automatically places you in the
175 working directory (i.e. `$AGL_TOP/build`).
176 You can change this default behavior by adding the "-f" option to the
177 script's command line.
179 In the previous command, the "-m" option sets your machine to the previously
180 defined `MACHINE` variable.
181 The "-b" option defines your Build Directory, which is the
182 default `$AGL_TOP/build`.
183 Finally, the AGL features are provided to support building the AGL Demo image
184 for the Renesas board.
186 You can learn more about the AGL Features in the
187 "[Initializing Your Build Environment](./3_Initializing_Your_Build_Environment.md)"
190 3. **Examine the Script's Log:**
192 Running the `aglsetup.sh` script creates the `setup.log` file, which is in
193 the `build/conf` folder.
194 You can examine this log to see the results of the script.
195 For example, suppose the graphics drivers were missing or could not be extracted
196 when you ran the script.
199 <summary> In case of missing graphics drivers, you could notice an error message
200 similar to the following:</summary>
204 --- fragment /home/working/workspace_agl_master/meta-agl/templates/machine/h3ulcb/50_setup.sh
205 /home/working/workspace_agl_master /home/working/workspace_agl_master/build_gen3
206 The graphics and multimedia acceleration packages for
207 the R-Car Gen3 board can be downloaded from:
208 https://www.renesas.com/en-us/solutions/automotive/rcar-demoboard-2.html
210 These 2 files from there should be store in your'/home/devel/Downloads' directory.

241 The graphics and multimedia acceleration packages for
242 the R-Car Gen3 board BSP can be downloaded from:
243 <https://www.renesas.com/us/en/solutions/automotive/rcar-download/rcar-demoboard-2.html>
245 These 2 files from there should be stored in your
246 '/home/iotbzh/Downloads' directory.

249 ERROR: Script /home/iotbzh/workspace_agl/build/conf/setup.sh failed
255 ## 5. Checking Your Configuration
257 Aside from environment variables and parameters you establish through
258 running the `aglsetup.sh` script, you can ensure your build's configuration
259 is just how you want it by examining the `local.conf` configuration file.
261 You can find this configuration file in the Build Directory (e.g.
262 "$TOP_DIR/build/conf/local.conf").
264 In general, the defaults along with the configuration fragments the
265 `aglsetup.sh` script applies in the `local.conf` file are good enough.
266 However, you can customize aspects by editing the `local.conf` file.
268 "[Customizing Your Build](4_Customizing_Your_Build.md)"
269 section for common configurations you might want to consider.
271 **NOTE:** For detailed explanations of the configurations you can make
272 in the ``local.conf`` file, consult the
273 [Yocto Project Documentation](https://www.yoctoproject.org/docs/).
275 A quick way to see if you have the `$MACHINE` variable set correctly
276 is to use the following command:
279 grep -w -e "^MACHINE =" $AGL_TOP/build/conf/local.conf
282 Depending on the Renesas board you are using, you should see output
294 MACHINE = "h3-salvator-x"
297 If you ran the `aglsetup.sh` script as described in the
298 "[Making Sure Your Build Environment is Correct](./5_3_RCar_Gen_3.md#4-making-sure-your-build-environment-is-correct)"
299 section earlier, the "agl-devel", "agl-demo", "agl-netboot", "agl-appfw-smack", and
300 "agl-localdev" AGL features will be in effect.
301 These features provide the following:
304 * Some tweaks, including a disabled root password
306 * The TCF Agent for easier application deployment and remote debugging
307 * Some extra system tools such as USB and bluetooth
308 * Support for the AGL demo platform
309 * [IoT.bzh](https://iot.bzh/en/) Application Framework plus
310 [SMACK](https://en.wikipedia.org/wiki/Smack_(software)) and
311 [Cynara](https://wiki.tizen.org/Security:Cynara)
315 This section shows the `bitbake` command used to build the AGL image.
316 Before running BitBake to start your build, it is good to be reminded that AGL
317 does provide pre-built images for developers that work with supported hardware.
318 You can find these pre-built images on the
319 [AGL Download web site](https://download.automotivelinux.org/AGL/release).
321 Start the build using the `bitbake` command.
323 **NOTE:** An initial build can take many hours depending on your
324 CPU and and Internet connection speeds.
325 The build also takes approximately 100G-bytes of free disk space.
327 For this example, the target is "agl-demo-platform":
330 bitbake agl-demo-platform
333 The build process puts the resulting image in the Build Directory:
336 <build_directory>/tmp/deploy/images/$MACHINE
339 ## 7. Booting the Image Using a MicroSD Card
341 To boot your image on the Renesas board, you need to do three things:
343 1. Update all firmware on the board.
344 2. Prepare the MicroSD card to you can boot from it.
347 **NOTE:** For subsequent builds, you only have to re-write the MicroSD
348 card with a new image.
350 ### Updating the Board's Firmware
352 Follow these steps to update the firmware:
354 1. **Update the Sample Loader and MiniMonitor:**
356 You only need to make these updates one time per device.
358 Follow the procedure found on the
359 eLinux.org wiki to update to at least version 3.02,
360 which is mandatory to run the AGL image ([R-car loader update](https://elinux.org/R-Car/Boards/Kingfisher#How_to_update_of_Sample_Loader_and_MiniMonitor)).
362 2. **Update the Firmware Stack:**
364 You only need to update the firmware stack if you are
365 using the Eel or later (5.0) version of AGL software.
367 M3 and H3 Renesas board are AArch64 platforms.
368 As such, they have a firmware stack that is divided across: **ARM Trusted Firmware**, **OP-Tee** and **U-Boot**.
370 If you are using the Eel (5.0) version or later of the AGL software, you must update
371 the firmware using the **[h3ulcb][R-car h3ulcb firmware update](http://elinux.org/R-Car/Boards/H3SK#Flashing_firmware)**
372 or **[m3ulcb][R-car m3ulcb firmware update](https://elinux.org/R-Car/Boards/M3SK#Flashing_firmware)** links from the
373 [Embedded Linux Wiki](https://www.elinux.org/Main_Page) (i.e. `elinux.org`).
375 The table in the wiki lists the files you need to flash the firmware.
376 You can find these files in the following directory:
379 $AGL_TOP/build/tmp/deploy/images/$MACHINE
382 **NOTE:** The Salvator-X firmware update process is not documented on eLinux.
384 ### Preparing the MicroSD Card
388 Plug the MicroSD card into your Build Host.
389 After plugging in the device, use the `dmesg` command as follows to
390 discover the device name:
395 [ 1971.462160] sd 6:0:0:0: [sdc] Mode Sense: 03 00 00 00
396 [ 1971.462277] sd 6:0:0:0: [sdc] No Caching mode page found
397 [ 1971.462278] sd 6:0:0:0: [sdc] Assuming drive cache: write through
398 [ 1971.463870] sdc: sdc1 sdc2
403 In the previous example, the MicroSD card is attached to the device `/dev/sdc`.
407 You can also use the `lsblk` command to show all your devices.
408 Here is an example that shows the MicroSD card as `/dev/sdc`:
413 NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
414 sda 8:0 0 167,7G 0 disk
415 ├─sda1 8:1 0 512M 0 part /boot/efi
416 ├─sda2 8:2 0 159,3G 0 part /
417 └─sda3 8:3 0 7,9G 0 part [SWAP]
418 sdb 8:16 0 931,5G 0 disk
419 └─sdb1 8:17 0 931,5G 0 part /media/storage
420 sdc 8:32 1 14,9G 0 disk
421 ├─sdc1 8:33 1 40M 0 part
422 └─sdc2 8:34 1 788M 0 part
427 **IMPORTANT NOTE:** Before re-writing any device on your Build Host, you need to
428 be sure you are actually writing to the removable MicroSD card and not some other
430 Each computer is different and removable devices can change from time to time.
431 Consequently, you should repeat the previous operation with the MicroSD card to
432 confirm the device name every time you write to the card.
434 To summarize this example so far, we have the following:
436 * The first SATA drive is `/dev/sda`.
438 * `/dev/sdc` corresponds to the MicroSD card, and is also marked as a removable device.
439 You can see this in the output of the `lsblk` command where "1" appears in the "RM" column
442 Now that you have identified the device you are going to be writing the image on,
443 you can use the `bmaptool` to copy the image to the MicroSD card.
445 Your desktop system might offer a choice to mount the MicroSD automatically
447 For this example, assume that the MicroSD card mount directory is stored in the
450 Following are example commands that write the image to the MicroSD card:
453 cd $AGL_TOP/build/tmp/deploy/images/$MACHINE
454 bmaptool copy ./agl-demo-platform-$MACHINE.wic.xz <boot_device_name>
457 Alternatively, you can leave the image in an uncompressed state and write it
461 sudo umount <boot_device_name>
462 xzcat ./agl-demo-platform-$MACHINE.wic.xz | sudo dd of=<boot_device_name> bs=4M
466 ### Booting the Board
468 Follow these steps to boot the board:
470 1. Use the board's power switch to turn off the board.
472 2. Insert the MicroSD card into the board.
474 3. Verify that you have plugged in the following:
476 * An external monitor into the board's HDMI port
478 * An input device (e.g. keyboard, mouse, touchscreen, and so forth) into the board's USB ports.
480 4. Use the board's power switch to turn on the board.
482 After a few seconds, you will see the AGL splash screen on the display and you
483 will be able to log in at the console's terminal or using the graphic screen.
485 ## 8. Setting Up the Serial Console
487 Setting up the Serial Console involves the following:
489 * Installing a serial client on your build host
490 * Connecting your build host to your Renesas board's serial port
491 * Powering on the board to get a shell at the console
492 * Configuring U-Boot parameters
493 * Logging into the console
494 * Determining the board's IP address
496 ### Installing a Serial Client on Your Build Host
498 You need to install a serial client on your build host.
500 [GNU Screen](https://en.wikipedia.org/wiki/GNU_Screen),
501 [picocom](https://linux.die.net/man/8/picocom),
503 [Minicom](https://en.wikipedia.org/wiki/Minicom).
505 Of these three, "picocom" has less dependencies and is therefore
506 considered the "lightest" solution.
508 ### Connecting Your Build Host to Your Renesas Board's Serial Port
510 You need to physically connect your build host to the Renesas board using
511 a USB cable from the host to the serial CP2102 USP port (i.e. Micro USB-A port)
512 on the Renesas board.
516 Once you connect the board, determine the device created for the serial link.
517 Use the ``dmesg`` command on your build host.
523 [2097783.287091] usb 2-1.5.3: new full-speed USB device number 24 using ehci-pci
524 [2097783.385857] usb 2-1.5.3: New USB device found, idVendor=0403, idProduct=6001
525 [2097783.385862] usb 2-1.5.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
526 [2097783.385864] usb 2-1.5.3: Product: FT232R USB UART
527 [2097783.385866] usb 2-1.5.3: Manufacturer: FTDI
528 [2097783.385867] usb 2-1.5.3: SerialNumber: AK04WWCE
529 [2097783.388288] ftdi_sio 2-1.5.3:1.0: FTDI USB Serial Device converter detected
530 [2097783.388330] usb 2-1.5.3: Detected FT232RL
531 [2097783.388658] usb 2-1.5.3: FTDI USB Serial Device converter now attached to ttyUSB0
536 The device created is usually "/dev/ttyUSB0".
537 However, the number might vary depending on other USB serial ports connected to the host.
539 To use the link, you need to launch the client.
540 Here are three commands, which vary based on the serial client, that show
541 how to launch the client:
545 $ picocom -b 115200 /dev/ttyUSB0
551 $ minicom -b 115200 -D /dev/ttyUSB0
557 $ screen /dev/ttyUSB0 115200
560 ### Powering on the Board to Get a Shell at the Console
562 Both the Pro and Premier kits (e.g.
563 [m3ulcb](https://elinux.org/R-Car/Boards/M3SK) and
564 [h3ulcb](https://elinux.org/R-Car/Boards/H3SK#Hardware)) have nine
565 switches (SW1 through SW9).
566 To power on the board, "short-press" SW8, which is the power switch.
568 Following, is console output for the power on process for each kit:

662 ## 9. Setting-up U-boot
663 ### Configuring U-Boot Parameters
665 Follow these steps to configure the board to use the MicroSD card as the
666 boot device and also to set the screen resolution:
668 1. As the board is powering up, press any key to stop the autoboot process.
669 You need to press a key quickly as you have just a few seconds in which to
672 2. Once the autoboot process is interrupted, use the board's serial console to
673 enter <b>printenv</b> to check if you have correct parameters for booting your board:
676 Here is an example using the <b>h3ulcb</b> board:
683 bootargs=console=ttySC0,115200 root=/dev/mmcblk1p1 rootwait ro rootfstype=ext4
684 bootcmd=run load_ker; run load_dtb; booti 0x48080000 - 0x48000000
686 fdt_high=0xffffffffffffffff
687 initrd_high=0xffffffffffffffff
688 load_dtb=ext4load mmc 0:1 0x48000000 /boot/r8a7795-h3ulcb.dtb
689 load_ker=ext4load mmc 0:1 0x48080000 /boot/Image
693 ver=U-Boot 2015.04 (Jun 09 2016 - 19:21:52)
695 Environment size: 648/131068 bytes
701 Here is a second example using the <b>m3ulcb</b> board:
707 bootargs=console=ttySC0,115200 root=/dev/mmcblk1p1 rootwait ro rootfstype=ext4
708 bootcmd=run load_ker; run load_dtb; booti 0x48080000 - 0x48000000
710 fdt_high=0xffffffffffffffff
712 initrd_high=0xffffffffffffffff
713 load_dtb=ext4load mmc 0:1 0x48000000 /boot/r8a7796-m3ulcb.dtb
714 load_ker=ext4load mmc 0:1 0x48080000 /boot/Image
718 ver=U-Boot 2015.04 (Nov 30 2016 - 18:25:18)
720 Environment size: 557/131068 bytes
725 3. To boot your board using the MicroSD card, be sure your environment is set up
729 setenv bootargs console=ttySC0,115200 ignore_loglevel vmalloc=384M video=HDMI-A-1:1920x1080-32@60 root=/dev/mmcblk1p1 rw rootfstype=ext4 rootwait rootdelay=2
730 setenv bootcmd run load_ker\; run load_dtb\; booti 0x48080000 - 0x48000000
731 setenv load_ker ext4load mmc 0:1 0x48080000 /boot/Image
736 **NOTE** : Refer [here](https://elinux.org/R-Car/Boards/Yocto-Gen3-CommonFAQ/Which_dtb_file_is_required_to_boot_linux_on_the_R-Car_Starter_Kit_board_%3F) for more information.
738 Make sure your ``load_dtb`` is set as follows :
740 * **H3SK v2.0(DDR 4GB)** : `$ setenv load_dtb ext4load mmc 0:1 0x48000000 /boot/r8a7795-h3ulcb.dtb`
742 * **H3SK v2.0(DDR 8GB)/v3.0(DDR 8GB)** : `$ setenv load_dtb ext4load mmc 0:1 0x48000000 /boot/r8a7795-h3ulcb-4x2g.dtb`
744 * **M3SK v1.0** : `$ setenv load_dtb ext4load mmc 0:1 0x48000000 /boot/r8a7796-m3ulcb.dtb`
746 * **M3SK v3.0** : `$ setenv load_dtb ext4load mmc 0:1 0x48000000 /boot/r8a7796-m3ulcb-2x4g.dtb`
748 * **H3SK with a Kingfisher board** : `$ setenv load_dtb ext4load mmc 0:1 0x48000000 /boot/r8a7795-h3ulcb-kf.dtb`
750 * **M3SK with a Kingfisher board** : `$ setenv load_dtb ext4load mmc 0:1 0x48000000 /boot/r8a7796-m3ulcb-kf.dtb`
752 5. Save the boot environment:
765 ## 10. Troubleshooting
766 ### Logging Into the Console
768 Once the board boots, you should see the
769 [Wayland display](https://en.wikipedia.org/wiki/Wayland_(display_server_protocol))
770 on the external monitor.
771 A login prompt should appear as follows depending on your board:
776 Automotive Grade Linux ${AGL_VERSION} h3ulcb ttySC0
784 Automotive Grade Linux ${AGL_VERSION} m3ulcb ttySC0
789 At the prompt, login by using `root` as the login.
790 The password is "empty" so you should not be prompted for the password.
792 ### Determining the Board's IP Address
794 If your board is connected to a local network using Ethernet and
795 if a DHCP server is able to distribute IP addresses,
796 you can determine the board's IP address and log in using `ssh`.
800 Here is an example for the m3ulcb board:
805 Last login: Tue Dec 6 09:55:15 UTC 2016 on tty2
806 root@m3ulcb:~# ip -4 a
807 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
808 inet 127.0.0.1/8 scope host lo
809 valid_lft forever preferred_lft forever
810 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
811 inet 10.0.0.27/24 brd 10.0.0.255 scope global eth0
812 valid_lft forever preferred_lft forever
820 In the previous example, IP address is 10.0.0.27.
821 Once you know the address, you can use `ssh` to login.
822 Following is an example that shows logging into SSH and then
823 displaying the contents of the `/etc/os-release` file:
828 Last login: Tue Dec 6 10:01:11 2016 from 10.0.0.13
829 root@m3ulcb:~# cat /etc/os-release
