SK-AM62: SDK 9.0 flashing error.

Hi,

This mostly looks like Stage1 is failing to completely receive or boot the Stage 2 image & so the error comes. Before we debug this further, could you please clarify the following questions:

• Are you working with TI board or custom board?
• Does this issue occur every time or randomly?
• Does the issue occur with previous SDK version also?

Thanks & Regards,

Prashant

Hello Prashant,

• I am using a TI board.
• This issue happened every time.
• I did not use the previous SDK version.

Thank you very much.

Hello Seunghyun,

Sorry, I forgot to ask if you are using a GP or HSFS device. Could you please clarify the same?

Thanks!

Hello Prashant,

May I know how to check the device type?

Best regards,

Hello Seunghyun,

Please refer to the following FAQ to know the device type

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

Hello Prashant,

Thank you for your advice. The type is 'HSFS'

('DeviceType           :', 'HSFS')

Best regards,

Hello Seunghyun,

Thank you for following & providing all the details.

Since the device type is HSFS, the issue can't be because of using incorrect images as you are using the HSFS images all along. I believe the issue must be because of Stage 1 failing to boot Stage 2 somehow.

I am attaching below SBL UART Uniflash images generated on my side with which I have successfully tested the flashing procedure. Could you please once try the flashing procedure with the attached images & let me know how it goes.

Hello Prashant,

I copied them.

I executed the script.

boot$

But I faced a different error as above.

Hi Seunghyun,

Thank you for following. The images I shared were tested successfully on my side & if you are using TI AM62A board then the images should have worked.

Could you please reinstall the SDK & then try the flashing procedure again. If it still fails, could you please share the following:

1) The full parsed output from the SocID parser script you followed from the previous FAQ.

2) The Stage1 & Stage2 Uniflash images with which the flashing is failing. I will try them once on my board & see if it works.

Regards,

Prashant
