2008-10-07 07:44:04 Custom BF561 board -- loading linux kernel hangs

Thomas Langås (NORWAY)

Message: 63215

I finally got u-boot working on my custom board, and I'm now struggling with the linux-kernel. This is the bdinfo from u-boot:

U-Boot = U-Boot 1.1.6-svn1340 (ADI-2009R1-pre) (Oct 1 2008 - 15:08:30)

CPU = bf561-0.5

Board = custom-board

VCO = 500 MHz

CCLK = 500 MHz

SCLK = 100 MHz

boot_params = 0x00000000

memstart = 0x00000000

memsize = 0x08000000

flashstart = 0x20000000

flashsize = 0x04000000

flashoffset = 0x00000000

ethaddr = 00:11:22:33:44:55

ip_addr = 192.168.0.15

baudrate = 115200 bps

This is what I get when trying to boot my uImage.initramfs located at 0x20100000:

bfin> run flashboot

## Booting image at 20100000 ...

Image Name: Linux-2.6.26.5-ADI-2009R1-pre-sv

Image Type: Blackfin Linux Kernel Image (gzip compressed)

Data Size: 3145643 Bytes = 3 MB

Load Address: 00800000

Entry Point: 00a2cf68

Verifying Checksum ... OK

Uncompressing Kernel Image ... OK

Starting Kernel at = a2cf68

I've also tried to copy the image from flash to memory (with uboot cp.b) and then boot from ram instead, but it's the same problem. Is there a list / doc somewhere on where to start looking when experiencing problems like this?

In advance, thanks!

Thomas

I see why I didn't get any output (no early printk enabled-string) but I don't see why it crashes. Should it crash like this when unable to open console?
