Hi, Albert: I found new u-boot source code had some PIC related question. I succeeded to boot self-uncompressed u-boot.bin now.
I reviewed self-uncompressed header code (similar with Linux kernel piggy header), found: The header code would de-compress compressed uboot.bin to 0x0000 8000 dram location, and then jump to run it. Because i compiled uboot with "SYS_TEXT_BASE=0x03F80000" in board.cfg before. So boot failed. Now, I changed SYS_TEXT_BASE=0x08000000 in boards.cfg. So, boot the compressed u-boot.bin successfully!

At what address does it place the uncompressed load?
