Hi all,
I need some help loading a custom UBL into NOR on custom hardware. I am
trying to use DVFlasher to do this. I am sure that the boot configuration
pins are correct. I am pretty sure the NOR part is working fine. If I
issue a DVFlasher -enor, It appears to work correctly.
I edited the UBL source for my DDR. That consisted of the register values
in dm644x.c, .ddrram2 in ubl_davinci.lds, MAX_IMAGE_SIZE and RAM_END_ADDR in
ubl.h.
I don't know if I am using DVFlasher correctly. What I think is correct is:
DVFlasher_1_10.exe -fnorbin -useMyUBL ubl_davinci_nor.bin u-boot.bin -v
Here is what I am seeing:
-----------------------------------------------------

It then continues to loop through the BOOTPSP part until I stop it.
I am a bit confused on why I am seeing the "S-record Decode Failed."
Any help would be greatly appreciated.
Thanks
