PROCESSOR-SDK-AM64X: Not able to flash application using uniflash_uart software

Part Number: PROCESSOR-SDK-AM64X
Other Parts Discussed in Thread: UNIFLASH, TMDS64EVM

Hello,

I am not able to flash again using the uart_uniflash program. It gets stuck during eMMC initialization it seems. Any idea what could go wrong here? My understanding is that the uniflash gets loaded into RAM directly and open up options to flash (SBL and/or Application) to eMMC from laptop using the python script ( c:> python uart_uniflash.py -p COMx --cfg=sbl_mrch.cfg ). Just wondering why, it gets stuck here (while loop)!

Any suggestion would be helpful.

Thanks!

Hello,

Can you please clarify the following couple of questions:

1) Is this a TI or custom board with custom eMMC part?

2) Are you trying to flash SBL/application into eMMC?

3) What procedure are you following for flashing?

Thanks!

1. The eMMC is from TI (please have a look at the screenshot).

2.yes, you are right. I could do it but for some reason I am not able to now.

3. I open the uniflash_uart program, go to debug session, once I hit the play, it gives me couple of options, one of them is to flash into eMMC. After I select it, I start the python script. It writes to eMMC...

TI does not supply eMMC. What I wanted to know if if you are using a TI board (TMDS64EVM) or a custom board?

This does not sound like sbl_uart_uniflash since it involves putting the board in UART bootmode and directly running the Python script. Have you modified the sbl_uart_uniflash?

Can you try the original UART Uniflash procedure
