Few of us as energetic, or any smarter, Gene. I wuzn't going to say anything, as it's over a decade since I played with u-boot, making my few pages of notes more historical than currently relevant. Syncing my understanding with your issue, U-boot could be used different ways, including: 1. as a standalone bootloader residing in flash & relocating itself to RAM on startup automatically => "FLASH version" When I did it, all that was needed was a kernel image and ramdisk at known flash addresses. But how is u-boot configured on the rockchip? The bumpf at: http://rockchip.wikidot.com/linux-user-guide#toc20 seems cryptic and of limited usefulness, but this seems to be the goods: http://opensource.rock-chips.com/wiki_Boot_option There the whole boot sequence is laid out, with kernel and rootfs, which can be on various media, at your choice. (4 different boot flows) Does the method for one of those media look good to you? (The load offsets for kernel and rootfs seem to be 0x8000 and 0x40000 respectively, if my quick scan is near the mark.) It would be fun to see what can be done with the rockchip.
