Hello,
Thanks again your replay.
The dk2 DTS just ‘#include “stm32mp157a-dk1.dts”’ and changes the model name so I consider them the same in terms of the ATF. And yes, I use commit 75090fd.
I recall seeing something like this a long time before. Could be something silly as the tsv file missing something.
The ST ATF has a case for USB
#ifdef STM32MP_USB
case BOOT_API_CTX_BOOT_INTERFACE_SEL_SERIAL_USB:
INFO("Using USB\n");
break;
#endif
Where as the other ATF does not. It seems that I am not specifying the Boot device correctly.
