[External]Re: Uboot upgrade from 2016 to 2020

[Manea, Alexandru (Alexandru)]

Hi Sinan,

First thanks for replying. I do hope you will be able to help me a bit.
The board is PPCE5500 used for Avaya IP500L platform.

What I noticed for hanging is that it hangs when setting mtspr    IVPR, r0 in start.s although this seems correct: CONFIG_SYS_MONITOR_BASE at h

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.
