Carlos If you are using the ubl_nand.bin that we provide (or maybe got from spectrum digital) then you will need to set your start address to 0x100(or 0x120 to be more exact). I've mentioned before that the binary file contains 0x100 bytes at the beginning for self-copy code (code which isn't needed for a NAND boot but it's there anyway.) Your memory dumps look good though.

Thank you so much for your crucial help and patience. I reversed my header bytes. I also noticed that you see e1a00000 for a nop (807000f0: ee070f15 e1a00000 e1a00000 e1a00000 ................) So I think my program's byte order is also ok as I see e1a00000 for a nop, and I could also see some readable text at certain addresses. I don't know if I am writing the header and the ubl_nand.bin at the righ nand addresses. I am using a 0x4000 offset for the header and 0x4200 for ubl_nand.bin I also put nops between the header and ubl_nand.bin, who really starts at 0x4200, and I have S3:0000111110 and J4:NAND. This is my dump for nand's offset 0x4000. Now I think it *SHOULD* boot (but it doesn't): DaVinci EVM # nand read 0x80000000 0x4000 0x4000 NAND read: device 0 offset 16384, size 16384 ... 16384 bytes read: OK DaVinci EVM # md 0x80000000 80000000: a1aced00 00000020 0000001c 00000001 .... ........... 80000010: 00000001 00000000 e1a00000 e1a00000 ................ 80000020: e1a00000 e1a00000 e1a00000 e1a00000 ................ 80000030: e1a00000 e1a00000 e1a00000 e1a00000 ................ 80000040: e1a00000 e1a00000 e1a00000 e1a00000 ................ 80000050: e1a00000 e1a00000 e1a00000 e1a00000 ................ 80000060: e1a00000 e1a00000 e1a00000 e1a00000 ................ 80000070: e1a00000 e1a00000 e1a00000 e1a00000 ................ 80000080: e1a00000 e1a00000 e1a00000 e1a00000 ................ 80000090: e1a00000 e1a00000 e1a00000 e1a00000 ................ 800000a0: e1a00000 e1a00000 e1a00000 e1a00000 ................ 800000b0: e1a00000 e1a00000 e1a00000 e1a00000 ................ 800000c0: e1a00000 e1a00000 e1a00000 e1a00000 ................ 800000d0: e1a00000 e1a00000 e1a00000 e1a00000 ................ 800000e0: e1a00000 e1a00000 e1a00000 e1a00000 ................ 800000f0: e1a00000 e1a00000 e1a00000 e1a00000 ................
