Hi Scott Wood
this is the patch I try to add nand spl boot for qi_lb60 board
this patch works fine under qi_lb60(ben nanonote) but there are three 'extern' lines under: nand_spl/board/qi/qi_lb60/nand_spl.c
those 'extern' lines already in jz4740.h, my question is when I remove those three lines under nand_spl/board/qi/qi_lb60/nand_spl.c, it will make u-boot-nand.bin break. can't boot the device anymore.
Are you *sure* that's the only difference between the working and non-working versions? Could you double-check?
By "can't boot", you mean that it builds cleanly (no errors or warnings), but nothing happens after power on?
Please give me some advice how to debug the error.
JTAG? Serial output?
