Subject: [U-Boot] Bad Data CRC ERROR: can't get kernel image!
Date: Wed, 14 Apr 2010 23:18:06 -0700 (PDT)	[thread overview]
Message-ID: <14731.34989.qm@web46107.mail.sp1.yahoo.com> (raw)





I am using u-boot version 2009-08
for customized PPC 440 based board.

Board is having 16MB Nor flash. I am
flashing the kernel image at 0xffdc0000, ramdisk at 0xff8c0000 and dtb at
0xff200000

When I pass bootm command through
u-boot prompt i.e ?bootm 0xffdc0000 0xff8c0000 0xff200000?

?

Kernel booting stops with
following error message.

## Booting kernel from Legacy
Image at ffdc0000 ...

??
Image Name:?? Linux-2.6.31-LE

??
Image Type:?? PowerPC Linux Kernel
Image (gzip compressed)

??
Data Size:??? 936145 Bytes = 914.2
kB

??
Load Address: 00000000

??
Entry Point:? 00000000

??
Bad Data CRC

??
ERROR: can't get kernel image!

?

When I print the data that we
calculated in image_check_dcrc() ?I found foloowing difference:

Calculated DCRC --------Data :
0xffdc0040 Len: 0xe48d1 dcrc: 0x5fe26d1e

From image_get_dcrc function DCRC: 0x72e08293

?

And hence return (dcrc ==
image_get_dcrc (hdr)) this condition become false.

?

Please let me know your input on
this.
