AM2434: custom flash verify fail with python script flashing sbl_ospi

Other Parts Discussed in Thread: UNIFLASH

hi guys, i'm deal with a problem in flashing standart texas sbl_ospi with a custom flash.

i ran the flash_io e flash diag programs and there was no problems, the micro communicate properly with the flash.

When i run the uniflash python script to flash the sbl on the flash, something goes wrong. it seems that the number of bytes calculated by the scripts and the bytes size of the sbl don't look the same.

Executing command 3 of 3 ...
Command arguments : --file=C:/Users/rosario.fria/workspace_v12/HT-NET_sbl_ospi/sbl_ospi.Release.hs_fs.tiimage --flash-offset=0x00 --operation=flash
Sending C:/Users/USER/workspace_v12/HT-NET_sbl_ospi/sbl_ospi.Release.hs_fs.tiimage: 15%|██████████▏ | 45276/301893 [00:05<00:23, 11142.83bytes/s]

[STATUS] ERROR: Flash verify failed !!!

the sdk python script file name is: uart_uniflash.py 

command 1 and command 2 were completed with success.

Someone can help me?

    Hi Rosario,

    The small size difference (32 bytes) is expected because of the extra headers added by the uart_uniflash script for the flasher application to know what needs to be done. But flash verify failure is concerning. Were there any changes made to the SBL OSPI or UART UNIFLASH application?

    Hi Rosario,

    Can you let me know which version of the MCU+SDK are you using? Also which flash part are you using? Did you rebuild the sbl_uart_uniflash application with the changes for the custom flash?

    Regards,
