Next kernel image is limited to size 2MB. And currently uboot can be compiled to act as "kernel" image, so second stage bootloader can boot it. I spend some time to replace second (non signed) bootloader with something other, but really it is not possible. -- Pali Roh?r pali.rohar at gmail.com -------------- next part -------------- A non-text attachment was scrubbed...
