[External]Re: Uboot upgrade from 2016 to 2020

[Manea, Alexandru (Alexandru)]

Hi Sinan,

We have a very limited supply of boards, maybe one we have everything ongoing we could arrange for one.
Is there anything I can provide so you could help me out a bit? I’m stuck with this hanging situation and I’m running out of idea why it’s not working…as it matches most of the old working uboot settings…

Regards,
Alex

Is there something I can do to make sure uboot is actually being jumped to or why the hang? I've set the offsets to go to the _start_e500: instructions like the old uboot. I can share the traces I have if needed. Looking forward to an answer.

I don't have access to P50x0 or T10x0 boards to test and debug this

but I might try to see if I can get my hands on a T1040RDB or one of

your boards (e.g. IP500L). As Tom mentioned any help you can provide

is definitely very welcome here in this area.
