boot problem
Hi all,
I have a problem and now, it's weird to say, I pray to a kernel panic !
I'm working on smdk2410 and I have a u-boot version modified to boot from smartmedia. I want, or better I hope to boot 2.6.7 linux kernel. So, I create a zImage by compiling kernel and then I make:
gzip -9 zImage
./mkimage -A arm -O linux -T kernel -C gzip -a 0x30008000 -e 0x30008000 -n "Linux Kernel Image" -d zImage.gz uimage
At this point, I download uimage at 33000000 address from a tftp server.
SMDK2410 # tftpboot 33000000 uimage
TFTP from server 10.124.7.161; our IP address is 10.124.7.50
Filename 'uimage'.
Load address: 0x33000000
Loading: #################################################################
#################################################################
########################################################
done
Bytes transferred = 950519 (e80f7 hex)
Now I boot the kernel and I have:
SMDK2410 # bootm
## Booting image at 33000000 ...
Image Name: Linux Kernel Image
Created: 2004-11-17 13:50:56 UTC
Image Type: ARM Linux Kernel Image (gzip compressed)
Data Size: 950455 Bytes = 928.2 kB
Load Address: 30008000
Entry Point: 30008000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
Starting kernel ...
Uncompressing Linux................................................................... done, booting the kernel.
Nothing else !! Can anyone help me, please ? Which is my mistake ?
thanks in advance.
Best regards,
Alex

Alternatively, try a post-mortem dump of the log_buf area, see
http://www.denx.de/twiki/bin/view/DULG/LinuxPostMortemAnalysis
Or even better: attach your BDI2000 and debug the Linux kernel code.

[U-Boot-Users] Problem about Image Linux-2.4.25 running on Lite5200
In reply to Wolfgang DenkHello Wolfgang,
Sorry for bothering your again.
I burn Uboot to Lite5200 board, and build the Linux-2-4.25 with
following steps:
1) make mrproper
2) make icecube_5200_config
3) make oldconfig
4) make dep
5) make uImage
6) cp uImage to /tftp/MPC5200.
Then I download and run kernel as following :
1) tftp
2) bootm
After this, the linux kernel stop at the following lines:

The situation can be solved by reading the error messages, and trying to understand what they might mean. "unable to open an initial console" means that the kernel was not able to open the /dev/console device. Why not? Maybe it does not exist? Did you check if there is a /dev/console in your target's root filesystem?
<speculation on>
You are using the ELDK but did not read / follow the documentation, i. e. you did not run the ELDK_MAKEDEV scriot (and probably also not the ELDK_FIXOWNER script). Please see
