I've upgrade the capacity of Ram size from 256M to 512M on my custom board based on SEQUOIA.
(U-boot Version:2008.10-rc2)
I built a ramdisk image which is 72MB.( Also, I modified rd_size to 73728)
When I boot up my board, I've got a message like below.
.
.
RAMDISK: Compressed image found at block 0
crc error
EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended
.
.
Why does "crc error" occur??
If I use ramdisk image which is 4MB, "crc error" is not appeared.
And also if I use u-boot for 256MB on 512MB board, "crc error" is not appeared.
Here are my U-boot source which I modified to upgrade memory.
Sequoia.h
#define CFG_MBYTES_SDRAM (512)
Sdram.c
Everything Related DDR Control Register
Init.s
tlbentry( CFG_SDRAM_BASE_2nd, SZ_256M, CFG_SDRAM_BASE_2nd, 0, AC_R|AC_W|AC_X|SA_G|SA_I )
amcc-common.h
#define CFG_SDRAM_BASE_2nd 0x10000000
Thanks.
