I saw that.
I tried to update u-boot-1.3.4 to u-boot-2013.
I changed at91bootstrap's JUMP_ADDR from 0x23F00000 to 0x21F00000, as advised by previous posts.
Now I am getting the wrong board type error from the kernel. my board is an AT91SAM9G20EK_2MMC
I am having a hard time setting: #define MACH_TYPE_AT91SAM9G20EK_2MMC 2288 insted of #define MACH_TYPE_AT91SAM9G20EK 1624
In had to change buildroot's .config from: BR2_TARGET_UBOOT_BOARDNAME="at91sam9g20ek_2mmc_nandflash" to BR2_TARGET_UBOOT_BOARDNAME="at91sam9g20ek_nandflash" whihch I suspect is the problem.
I'm trying to change the buildroots output/build/uboot-custom manually, and rerun the build, but no luck yet.
My kernel is built with CONFIG_MACH_AT91SAM9G20EK_2MMC=y
So how do I force u-boot to agree?
Please have test with the following patch (add at91sam9g20ek 2mmc nandflash boot support) and check whether it will solve you problem.
You should use at91sam9g20ek_2mmc_nandflash to configure the u-boot
