I'm using SAM9G25 Evaluation board. I have to program my modified uboot to NAND flash.
How can program it to NAND flash WITH OUT using SAM-BA interface?

I did not find any links/documentation about using uboot itself to program new uboot/kernel to NAND flash.

Thanks..

You'd think that TFTPBOOT and NAND WRITE/ERASE would work just like they do for the kernel and filesystem.

You could make provisions in your AT91BootStrap

You could use the SAM-BA loader, and customize the SAM-BA application, or just inject code via the loader (RomBOOT)

You could inject code via JTAG
