Firmwares (arm-trusted-firmware, U-boot...) are stored into eMMC and updated by using serial download. ## How to build the Flash Writer 1. Gets cross compiler. ``` $ cd ~/ $ wget https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch64-elf/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-elf.tar.xz $ tar xvf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-elf.tar.xz ``` 2. Prepare the source code ``` $ cd ~/ $ git clone https://github.com/renesas-rcar/flash_writer.git $ cd flash_writer $ git checkout rcar_gen3 ``` 3. Build the Flash Writer ``` $ make AArch=64 clean $ CROSS_COMPILE=~/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-elf/bin/aarch64-elf- make AArch=64 ``` Output the following image. ./AArch64_output/AArch64_Flash_writer_SCIF_DUMMY_CERT_E6300400_salvator-x.mot ## How to build the Firmware 1. In a temporary working directory, clone poky the poky repository and check out the dunfell branch: ``` git clone git://git.yoctoproject.org/poky cd poky git checkout dunfell .. ``` 2. Clone the Renesas BSP and it's dependent layers: ``` git clone https://github.com/renesas-rcar/meta-renesas cd meta-renesas git checkout dunfell-dev-4.14 cd .. git clone git://git.openembedded.org/meta-openembedded cd meta-openembedded git checkout dunfell cd .. ``` 3. Clone the reference hardware BSP layer: ``` git clone https://gerrit.automotivelinux.org/gerrit/AGL/meta-agl-refhw ``` 4. Create a build environment: ``` . ./poky/oe-init-build-env build ``` 5. Add the layers to `conf/bblayers.conf`, the `BBLAYERS` variable definition should look like: ``` BBLAYERS ?= " \ /home/user/workdir/poky/meta \ /home/user/workdir/poky/meta-poky \ /home/user/poky/meta-yocto-bsp \ /home/user/workdir/meta-openembedded/meta-oe \ /home/user/workdir/meta-openembedded/meta-python \ /home/user/workdir/meta-renesas/meta-rcar-gen3 \ /home/user/workdir/meta-agl-refhw/meta-agl-refhw-gen3 \ " ``` 6. Add the machine setting to `conf/local.conf`, for example: ``` echo MACHINE=agl-refhw-h3 >> conf/local.conf ``` 7. Build the firmware: ``` bitbake arm-trusted-firmware optee-os u-boot ``` 8. Afterwards, the firmware files will be in the directory `tmp/deploy/images/agl-refhw-h3`. ## How to Flash Firmware 1. Connect reference hardware board to the development PC by using USB serial cable. 2. Open a serial console (like Teraterm in Windows, or gtkterm in Ubuntu that can easily send files) with a baudrate of 115200n8. 3. Set bit2 of SW2221 (on the top of SoC board) to "off"which turns SW2221 to be off,off,off,off. 4. Power on the reference board, you will find fillowing message outputed on the serial console: ``` SCIF Download mode (w/o verification) (C) Renesas Electronics Corp. -- Load Program to SystemRAM --------------- please send ! ``` 5. Use console application menu to send the flash writer binary provided: ``` AArch64_Flash_writer_SCIF_DUMMY_CERT_E6300400_salvator-x.mot ``` 6. After file is transferred correctly, following message will be outputed: ``` Flash writer for R-Car H3/M3/M3N Series V1.11 Feb.12,2020 > ``` 7. Set reference board to boot from eMMC. \> **EM_SECSD** Please Input EXT_CSD Index(H'00 - H'1FF) :**b1** EXT_CSD[B1] = 0x00 Please Input Value(H'00 - H'FF) :**a** EXT_CSD[B1] = 0x0A \> **EM_SECSD** Please Input EXT_CSD Index(H'00 - H'1FF) :**b3** EXT_CSD[B3] = 0x00 Please Input Value(H'00 - H'FF) :**8** EXT_CSD[B3] = 0x08 \>**EM_DCSD** [CSD Field Data] [127:126] CSD_STRUCTURE 0x03 [125:122] SPEC_VERS 0x04 [119:112] TAAC 0x27 [111:104] NSAC 0x01 [103: 96] TRAN_SPEED 0x32 [ 95: 84] CCC 0x00F5 [ 83: 80] READ_BL_LEN 0x09 [ 79: 79] READ_BL_PARTIAL 0x00 [ 78: 78] WRITE_BLK_MISALIGN 0x00 [ 77: 77] READ_BLK_MISALIGN 0x00 [ 76: 76] DSR_IMP 0x00 [ 73: 62] C_SIZE 0x0FFF [ 61: 59] VDD_R_CURR_MIN 0x06 [ 58: 56] VDD_R_CURR_MAX 0x06 [ 55: 53] VDD_W_CURR_MIN 0x06 [ 52: 50] VDD_W_CURR_MAX 0x06 [ 49: 47] C_SIZE_MULT 0x07 [ 46: 42] ERASE_GRP_SIZE 0x1F [ 41: 37] ERASE_GRP_MULT 0x1F [ 36: 32] WP_GRP_SIZE 0x0F [ 31: 31] WP_GRP_ENABLE 0x01 [ 30: 29] DEFAULT_ECC 0x00 [ 28: 26] R2W_FACTOR 0x03 [ 25: 22] WRITE_BL_LEN 0x09 [ 21: 21] WRITE_BL_PARTIAL 0x00 [ 16: 16] CONTENT_PROT_APP 0x00 [ 15: 15] FILE_FORMAT_GRP 0x00 [ 14: 14] COPY 0x01 [ 13: 13] PERM_WRITE_PROTECT 0x00 [ 12: 12] TMP_WRITE_PROTECT 0x00 [ 11: 10] FILE_FORMAT 0x00 [ 9: 8] ECC 0x00 [ 7: 1] CRC 0x00 8.
