AM625: flash on AM625 custom board

?? ??

Part Number: AM625
Other Parts Discussed in Thread: UNIFLASH, SK-AM62-LP

Tool/software:

I want to write to OSPI using a custom AM625 board.
I am trying to run examples/drivers/ospi/ospi_flash_diag first because I cannot configure OSPI.

When I write using uart_bootloader.py, I get the following error.
[STATUS] ERROR: Application load FAILED !!!

Since I am using NT6AN256M16AC for DDR, I output the settings in syscfg and applied them to sbl_uart_uniflash.
Reference Design SK-AM62-LP with NT6AN256M16AC is used as is.

Are there any other areas that need to be configured?

Please look at the correct way to run the OSPI Flash Diagnostics.

The steps are mentioned here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/11_00_00_16/exports/docs/api_guide_am62x/CUSTOM_FLASH_SUPPORT_GUIDE.html

Let me know if the above does not help you out and what gaps you see in the documentation.

Thanks for the reply.

I am trying to look at that page and try it, but I am not able to start the ospi_flash_diag with sbl_uart.
I am thinking that since it is for R5 core, it is not possible to write with CCS. So I am writing with sbl_uart.

I am thinking that my DDR settings are wrong.

This is a correct understanding.

Please check on this front.

Also, check if the images you are flashing needs to be HS FS or not? https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1228618/faq-am6xx-how-to-check-if-device-type-is-hs-se-hs-fs-or-gp
