Hi @CarlosAM_INTEL ,
Just to add some more information, I have used a DediProg SF600Plus-G2 to read the the contents of the BIOS flash on the CRB, saved it to a file called "intel-bios-flash.bin", but this was rejected as an IFWI_IN image as well with the error "BIOS image is too big to fit into BIOS region!"
How can I stitch my read-back BIOS with my SlimBootloader source code?
