Part Number: AM2634
Other Parts Discussed in Thread: UNIFLASH

Hello,

I converted my board to ES.
I am trying to flash my application again but SBL UART uniflash is not downloading SBL QSPI.
I don't know what is the problem.

Yours,

Hello Abdelrhman,

Can you check if the guidance Aakash provided previously can help with this situation, it looks to be the same issue from the screenshots but with your device being a little newer in terms of revisions: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1203655/am2634-hs_se-device-flash/4539651#4539651

Best Regards,

Hello,

Thanks, I will check that.

Can you guide me on how to change the dummy keys with my newer keys?

Hi Abdelrhman Afifi,

You need to rebuilt your SBL with HS-SE device keys to make sure they are functional.

Checkout the documentation of TIFS-MCU for detailed steps on the same - https://software-dl.ti.com/secure/software/sitara-sec/AM263X-RESTRICTED-SECURITY/TIFS_MCU/v08_06/tifs_am263x_08_06_00_05_docs_only/docs/api_guide_am263x/html/EXAMPLES_HSM_GET_VERSION.html?__gda__=1692215288_da2482db2caddebf23ecffed2936eb5d
