+## About
+Reference hardware board with R-Car H3 SoC is made by Panasonic for AGL community.
+
+## Difference to Salvator-XS When Flashing Firmware
+
+The HyperFlash/QSPI flash switch function is not implemented on reference
+hardware board at present, HyperFlash and QSPI flash are not used.
+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 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.

+8. Flash firmware
+ The firmware are supposed to be stored on eMMC as following:
+
+ Name | Load address | eMMC partition | Flash address | Description
+ --------------------------------------|-----------------------|-----------------------|-----------------------|-----------------------------
+ bootparam_sa0-4x2g.srec | H'E6320000 | 1 | H'000000 | Boot parameter
+ bl2-salvator-x-4x2g.srec | H'E6304000 | 1 | H'00001E | bl2 loader
+ cert_header_sa6-4x2g.srec | H'E6320000 | 1 | H'000180 | Certification
+ bl31-salvator-x-4x2g.srec | H'44000000 | 1 | H'000200 | bl3 loader
+ tee-salvator-x.srec | H'44100000 | 1 | H'001000 | OP-Tee
+ u-boot-elf-salvator-xs-4x2g.srec | H'50000000 | 2 | H'000000 | U-boot
+
+ You can find these firmwares in the AGL build directory $AGL_TOP/build/tmp/deploy/images/salvator-x
+ and you can flash them by using **EM_W** command as following:
+
+ \> **EM_W**
+ \---------------------------------------------------------
+ Please select,eMMC Partition Area.
+ 0:User Partition Area : 62496768 KBytes
+ eMMC Sector Cnt : H'0 - H'07733FFF
+ 1:Boot Partition 1 : 32640 KBytes
+ eMMC Sector Cnt : H'0 - H'0000FEFF
+ 2:Boot Partition 2 : 32640 KBytes
+ eMMC Sector Cnt : H'0 - H'0000FEFF
+ \---------------------------------------------------------
+ Select area(0-2)> **\<Enter the eMMC partition number above, Ex.'1' \>**
+ -- Boot Partition X Program -----------------------------
+ Please Input Start Address in sector : **\<Enter the Flash address above, Ex.'1e'\>**
+ Please Input Program Start Address : **\<Enter the Load address above, Ex. 'e6304000'\>**
+ Work RAM(H'50000000-H'50FFFFFF) Clear....
+ please send ! ('.' & CR stop load)
+ **\<Send the fimware file above by using console appliction, Ex. send 'bl2-salvator-x-4x2g.srec'\>**
+
+9. Power off the board.
+10. Reset bit2 of SW2221 (on the top of SoC board) to "on", which turns SW2221 to be
+ off,on,off,off
