Subject: [U-Boot] [ Ramdisk crc error ]
Date: Fri, 14 Nov 2008 18:40:56 +0900	[thread overview]
Message-ID: <000301c9463d$18434160$48c9c420$@com> (raw)

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.
