Yes that can happen, I suggested that some parts of the SPL are missing=20 - either the binary flashed is smaller than the real size (and the DTB,=20 being at the end is not copied...), or the value inside the 6th vector is wrong, and the first stage=20 bootloader is not copying enough data from NAND to RAM when executing=20 the SPL binary. The first stage BL only copies the number of bytes given=20 by 6th vector value >=20 > Regards, > Simon >=20 >> >>> >>> AT91bootstrap works fine. >>> >>> I know there was the issue with the nand_header showing up for the SD c= ard but that shouldn=E2=80=99t effect the nand.
