[U-Boot] Hangs up after transferring control to kernel
I am trying to boot kernel 2.6.23 on an MPC8572DS board. It hangs on a bootm command after decompressing the kernel and the rootfs. I added some printings to u-boot where I can see that it transfers control to the kernel (can be seen in the attached file).
What could be the problem?

Where did you get a kernel for 8572 that is based on 2.6.23?

The kernel is from the ltib environment installed from Freescale BSP.

you should than use the u-boot from ltib. There ltib kernel is NOT expected to work w/the open source u-boot.

Found the problem, by mistake the RAM was limited to 255M with the environment variable "mem":
setenv bootargs mem=255M
It seems that the kernel uses address 256M for memory cam mappings. Thanks, -Eliad.
