Hi Magnus,
If U-boot had full NAND support for i.MX31, NAND would be detected somewhere between steps 7 and 8.
Thanks for the elaborate explanation. I did not find any detailed documentation for the same in the u-boot readme's.
See my explanation above. CONFIG_SKIP* is defined when compiling U-boot, but not when compiling SPL.
That explains why i swa the #warning spit out. So you mean the CONFIG_SKIP_LOWLEVEL_INIT and CONFIG_SKIP_RELOCATE_UBOOT get toggled during compile time only. I am still struggling to get the NAND boot working. I am not even seeing U-boot spit out the first line on the console "U-boot <version no> " when i power up subsequently. This is what i did to build and run. i) make mx31_pdk_nand_config ii) make Take U-boot-nand.bin and burn it at physical offset 0x0 of the NAND using Redboot loaded via JTAG. When i reset, i see nothing on the console. I may be missing something which applying the patches then. Remote gdb does not allow me to debug. If i put printfs in _start_armboot in board.c, looks like its not ven entering that function. Has the standard output and the serial console dev been initiliazed before this point i.e start_armboot?
Have you got a chance to post the patches to the mainline yet? Thanks, Alfred.
