Hi all, I am using DM355 based custom board with "MT29F16G08DAA" as a NAND chip.
I want to burn UBL and U-Boot in NAND. I am successfully able to boot the board using SD card. On U-Boot prompt (got using SD), I am trying to burn UBL and U-Boot using following commands. //UBL Descriptor mw.b 0x80700000 0x00 0x1000;mmcinit;cp.l 0x32000 0x80700000 0x14;md.b 0x80700000 0x14 nand unlock 0x40000 0x1000;nand erase 0x40000 0x1000;nand write 0x80700000 0x40000 0x1000 nand unlock 0x40000 0x1000;nand read 0x80700000 0x40000 0x1000;md.b 0x80700000 0x14 //UBL mw.b 0x80700000 0x00 0x4000;mmcinit;cp.l 0x4E2000 0x80700000 0x1B; nand unlock 0x80000 0x4000;nand erase 0x80000 0x4000;nand write 0x80700000 0x80000 0x4000 nand unlock 0x80000 0x4000;nand read 0x80700000 0x80000 0x4000;md.b 0x80700000 0x4000 But when I change switch boot mode to NAND, I am not able to see any messages on console and even board is not falling back to SD boot mode. As per sprufb3 page 153 there is the possibility of ECC errors, but I am not sure whether this is in my case. Does anyone faces similar issue or have any idea for this? Thanks and Regards, Jitendra
