I do not see anything obviously wrong right away. I assume it passes the
while loop?

Yes, the while loop exits. In fact, I think uboot powers up core1. I saw some piece of code. So I asserted that core1 starts on tramp func and I saw that SCU was manipulated. But I don't understand what is done after. Perhaps it is not compatible with A7 and/or i.MX7 ?

I've put a log into boot_ap_cpu() and it is not reached. Is there a way to test if something is wrong between tramp_mp_entry and boot_ap_cpu() ?
