　*For detailed information, please check the original page (English).

The original article was intended for older versions of the tools environment.

When using the latest development tool environment, refer to Rocketboards.org "SoCEDS and ARM Development Studio" and perform the following items.
- Installation
- Running the Tools
- SoC EDS Licensing

*Note: For Windows, Cygwin must be installed separately. The Cygwin setup procedure is also described on the above page, but the described procedure does not install python2 necessary for executing Flash Programming scripts.
When checking here, after comparing with the Cygwin environment attached to the old version (v18.1) of SoC EDS, the following packages were added and installed. "python2, bcrypt, ccrypt, libprocps8, tcsh"

Download the archive containing the script (flash_programmer.tgz)

Download the script "flash_programmer.tgz" published on the original page.

Unzip the file on your PC

● Extract "flash_programmer.tgz" on the host PC where SoC EDS is installed.

1. Start Embedded Command Shell.

2. Execute the TAR extraction command on the shell.

$ tar -xzvf ./flash_programmer.tgz

3. Change to the extracted directory.

$ cd flash_programmer

● The directory after expansion has the following structure.

●flash_programmer.py is the main script for flash writing.

●Other design files for the Arria® 10 SoC Development Kit are available for each boot source (NAND/QSPI/SDMMC) and board revision (Rev.B/Rev.C).

● Each design contains the following three files.

‐ \output_files\ghrd_10as066n2.sof … FPGA configuration data (.sof)

- \software\bootloader_extcfg_semihosting\devicetree.dtb … Device tree binary for U-Boot (.dtb)

‐ \software\bootloader_extcfg_semihosting\uboot-socfpga\u-boot … U-Boot itself (executable file)

* The standard design files are only for Arria® 10 SoC Development Kit, but by preparing design files with the same configuration, it is possible to apply the same mechanism to various target boards. .

* According to the information on the original page, the only supported device is Arria® 10 SoC. However, as far as the contents of the script are checked, some descriptions are prepared to support Arria® V SoC and Cyclone® V SoC in addition to Arria® 10 SoC. It seems that it may be possible to support Arria® V SoC and Cyclone® V SoC by modifying the contents. Please check the contents and operation of flash_programmer.py before using.

*For Arm® DS, download and unzip the flash_programmer_armds.zip attached to this article, and replace it with flash_programmer.py.

Prepare a design directory (naming rules)

● Prepare a design directory for storing design files for the original target directly under flash_programmer.

○ Naming rule: <device>_<bootsource>_<board_name>_design

- <device> = select from {a10 / av / cv}

- <bootsource> = select from {qspi/sdmmc/nand}

- <board_name> = specify a meaningful name for board identification

* Example (Arria® 10, QSPI boot, board name: testboard01): a10_qspi_testboard01_design

Create and store design files

● Store the following three files in the created design directory.

‐ \output_files\ghrd_10as066n2.sof … FPGA configuration data (.sof)

- \software\bootloader_extcfg_semihosting\devicetree.dtb … Device tree binary for U-Boot (.dtb)

‐ \software\bootloader_extcfg_semihosting\uboot-socfpga\u-boot … U-Boot itself (executable file)

* For the FPGA configuration data (.sof), use the file generated by the Quartus® project for the original target as it is.

* Since the following options must be specified for the U-Boot itself and the device tree, they must be created separately from those for production use.

- Enable External Configulation (check external_fpga_config on bsp-editor)

- Enable SemiHosting (Edit definition under U-Boot source tree)

[Before editing] #undef CONFIG_SEMIHOSTING

[After editing] #define CONFIG_SEMIHOSTING

Connection with target board

Connect the target board and host PC with a USB-Blaster (JTAG) cable. (Only this one connection is OK)

programming execution

After powering on the target board, just run flash_programmer.py on the Embedded Command Shell.

1. Start Embedded Command Shell.

2. Move to the directory where the script is extracted.

- $ cd flash_programmer

3. Script execution (Example: Arria® 10, QSPI, board name: testboard01 )

‐ $ ./flash_programmer.py --board=testtarget01 --soc=a10 --flash=qspi --operation=epv --address=0x0 --size=0x100000 --file=uboot_w_dtb-mkpimage.bin

* Please refer to RocketBoards.org for details of flash_programmer.py options.
(There is also a speed-up procedure using TFTP that is not covered in this article.)

Execution example

I will post the contents of the console display when programming is executed.
