Hi, experts:
I tried to add a self-compressed header in u-boot.bin on a Cortex-A9
single core platform.
Then, i tried to boot it.
But failed in board_init_f() function.
Has anybody tried to boot a self-compressed u-boot.bin ?
Best wishes,

Hi, experts:
Sorry!
Not self-compressed, it is self-uncompressed !

Hi, Albert:
The DRAM address map is : 0 --- 0x1000 (256MB) on my ARM
development board.
I configured "CONFIG_SYS_TEXT_BASE = 0x03F8" in config.mk when
compiling u-boot source code.
The self-uncompressed code also put the uncompressed image at 0x03F8

this has been moved out of config.mk ages ago. How old is your U-Boot
version?

Hi, Denk:
My code base is based on u-boot-2013.04 .
I followed board\samsung\smdkc100\config.mk , and put it into my board
related directory.
About SPL approach:
Did you suggest I put decompressed algorithm code into SPL code instead
of adding a self-uncompressed header?

You managed toi find a really bad example of code. This shou

So, is there any example SPL code which contains uncompressed algorithm
code?

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 0x 8000

Yes, just change the decompressed target address to 0x03F8 is also
ok!
