I have tried to imagine some issues, but I cannot find a clear reason. Building with your patch I checked that nand_spl is still less than 2KB code, and that matches the NAND page, as required by i.MX31 - so it is not a problem. Have you tried to disable the relocation, just to check if the relocation is an issue with CONFIG_SKIP_RELOCATE_UBOOT ? This is not a solution, but only to check what happens. > > I copied the nand_spl/board/karo/tx25/u-boot.lds to the mx31pdk one. > > I am not certain whether the CONFIG_SYS_TEXT_BASE should be changed or not: > > ifdef CONFIG_NAND_SPL > CONFIG_SYS_TEXT_BASE = 0x87ec0000 > else > CONFIG_SYS_TEXT_BASE = 0x87f00000 > endif I think they are ok - both addresses are valid RAM addresses. The relocation will move then the code at the end of the RAM. And as I understood from i.MX31 manual, the NFC controller does not use the IRAM at all, so the area pointed by your starting stack pointer should not be overwritten. > > If anyone has any comments/suggestions I will appreciate it. No great idea, really. Probably you need to attach a JTAG debugger and see what happens.
