I have a situation where the same Flash.bin file can boot an MMC card, but hang when booting over USB.
In both cases, I can see the FIT file is loaded, and the various items are identified and placed in their respective folders memory locations. The only difference I can see is that when jumping to 0x920000 (ATF), the USB booting hangs and ATF doesn't appear to execute. Is there some special command that I need to issue to unlock this memory to execute from it when booting from USB? I am calling enable_tzc380 from SPL, and I read the first 100 bytes and last 100 bytes and compared it to my bl31.bin file, and it appears to match, so I know I can read from it.

Check if the uart used on atf and uboot are mapping correctly (but this should because you can boot from sdcard)
As far as i can tell, I have not done any differently in the serial from the NXP downstream.
ENV_IS_EVERYWHERE in configs file. It's no PMIC a problem when you jump in atf?
I have experimented with and without ENV_IS_EVERYWHERE, but that only seemed to help my imx8m Nano when jumping from ATF -> U-Boot. As for my Mini, the jump from SPL->ATF seems to be the issue.
What might the PMIC have to do with the ATF? From what I can tell, the PMIC is pre-configured and the default voltages appear to boot the
I have only seen this. I don't say that is connected. If the voltage are ok and you don't need to program it I don't see the problem
MMC. i had to disable the PMIC driver in order to make room for the USB code. I have a few lines of code in my board's spl.c file to setup a few registers based on NXP's original 8MM design and reference software.
Can you enable debug on the atf side?
Are you using binman to create the image flash.bin?
