I am trying to build a UEFI image for BirchStream Platform, my problem is the boot execution doesn't go any further than the 0x04 POST code. Since i don't have access to the FSP's source code and there is no integration guide , I don't know what the problem is. Any hints on this is appreciated. I also should mention that this FSP works fine with the vendor's UEFI and exits TempRamInitExit perfectly fine since it shows the 0x7F post code.
