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.
