[U-Boot-Users] bootm problem

Hi,
I have just started with U-boot. Can you help me this problem:
First I used TFTP command to load uImage for bootm, it's OK. Second, I used "bootm" for boot Linux, but when it ran to these lines:
[WRS]> bootm 100000 ## Booting image at 00100000 ... Image Name: Linux-2.4.25 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 704727 Bytes = 688.2 kB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ...

And it hang not continue.
Could you please tell me what is this problem?
Thank you for you help.

Why are you sending the same question twice within half an hour, and with a different subject???
DON'T DO THAT!

I would bet that NFS is not running on 192.168.1.248. Your kernel command line is trying to point the newly booted kernel to access its root filesystem through an NFS mount point on 192.168.1.248, specifically, th directory: /opt/eldk/ppc_8xx.
1) make sure NFS is running, on RHL, try, e.g., '/etc/init.d/nfs status' 2) make sure you have a well-formed /etc/exports file try, e.g., '/opt/eldk/ppc_8xx *(rw,no_root_squash,no_all_squash)' 3) make sure the mount point '/opt/eldk/ppc_8xx' exists and contains an image of the ELDK PPC/8xx root filesystem 4) run 'exportfs -ra' after starting NFS the first time, to synchronize info 5) boot your target again
Cheers, T.mike
