Hi Timur,
Thanks for the reply, very informative.

Hello,
I'm using u-boot 1.3.0 from the latest FreeScale Linux BSP MPC8313E-RDB.
If I set TEXT_BASE = 0x100, so I could use BDI debugger to load into RAM
and run it out of RAM.
I'm ABLE to ping to the host from u-boot
But, if I set TEXT_BASE=0xFE00, and burn the image it into Flash,

That's rather old...

Hi, I have a board based on the Lite5200b, except that the serial console is on
PSC4 instead of PSC1.
Using the a custom U-boot (1.2.0) and kernel 2.6.21 (compiled for powerpc), I
managed to get U-boot to output on the console on PSC4, but the kernel
does not.
I had just modified lite5200b.dts
