Sorry about the confusion. It was meant to say that the first block is smaller than the U-Boot Binary. > U-Boot will NOT fit into a 16 kB block.

So I guess that my best option would be to use a small primary bootloader to boot U-Boot from RAM. If I am reading everything correctly, I should have to change the reset and start locations (.resetvec and .bootpg) along with the setup of the MMU (as all TLB Entries are cleared currently.) I'm probably missing other steps that are required, I'll be looking at the startup code in more detail. Do you see any reasons why what I am suggesting may not be feasible at all? I would really like to use U-Boot as our bootloader (or secondary bootloader) if it is at all possible. Regards, -- Bradley Remedios bremedios at gmail.com
