The addresses are arbitrary, I picked 0x8000 for the SPL to preserve the existing 0x108000 for the normal u-boot but it doesn't have to be that way. The only requirement is that the SPL needs to know the address of the normal u-boot at compile time because it doesn't have any smarts to look for it. I'll move the SPL to 0x108000 and the normal u-boot to 0x208000 if that sounds more acceptable. -Allen -- nvpublic _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
