[U-Boot-Users] Linux kernel startup

[Tiju]

Hi Harald,

The serial issues were solved. As u said, the problem was with the RTS/CTS. I disabled all the hardware control signals and some modifications with the relocation section in the start.S and it started working.

Now the issue is with the kernel CRC32 check. I compiled a kernel with the smdk2440 architecture and I do the following.

$ arm-linux-objcopy -O binary -R .note -R .comment -S vmlinux linux.bin
$ gzip -9 linux.bin
$../u-boot-1.3.2/tools/mkimage -A arm -O linux -T kernel -C gzip -a0x30008000 -e 0x30008000 -n "Linux kernel" -d linux.bin.gz uImage.bin

The size of vmlinux is around 25MB. When converted to linux.bin it is 3GB, when gziped it is around 4MB and when done an mkimage it remains almost the same..

The output is as follows:

U-Boot 1.3.2 (Apr  7 2008 - 12:14:29)

DRAM:  128 MB
Flash: 32 MB
Using default environment

In:    serial
Out:   serial
Err:   serial
Hit any key to stop autoboot:  0
## Booting image at 33000000 ...
   Image Name:   Linux kernel
   Image Type:   ARM Linux Kernel Image (gzip compressed)
   Data Size:    4271633 Bytes =  4.1 MB
   Load Address: 30008000
   Entry Point:  30008000
   Verifying Checksum ... Bad Data CRC

What ever kernel image I load it tells the same ie. "Verifying Checksum ... Bad Data CRC". I even tried the uImage.bin which was available on openmoko site and the same error occurs.

Is the error with the bootloader or the kernel image? If so what are the changes to be done?

Thanks in advance.
