I have a flash.bin file that boots over MMC just fine, but when I use that same flash.bin file, it appears to hang after running ATF. I dumped some debug info for printing the handling of the FIT file, and I noticed the fit read sizes are also not consistent between MMC and USB loads with the identical flash.bin.
MMC booting is calling spl_romapi_raw_seekable_read, but the USB booting is not. Maybe this is normal.
I was hoping someone might have some pointers on how I can troubleshoot this. It's also weird to me that the various nodes are listed twice in the USB boot, but not the MMC boot.
I have poked around in the spl_imx_romapi.c file, but I am not seeing anything obvious.
SPL and ATF are executing, so it's partially decoding the FIT file and executing those two pieces correctly from what I can see.
