I use u-boot to download and > boot my image, and I don't get any serial output after the boot completes: By "poking characters out the serial port" I meant I literally coded up assembly functions to setup MMU translations and poke hex values at hard coded addresses. That's why it's "poor man's". If you had a working serial port out of the box, that would be a luxury ;). > => bootm 0x500000 > ## Booting image at 00500000 ... > Image Name: Kernel and Ramdisk > Created: 2008-03-01 0:09:57 UTC > Image Type: PowerPC Linux Multi-File Image (gzip compressed) > Data Size: 2430248 Bytes = 2.3 MB > Load Address: 00000000 > Entry Point: 00000000 > Contents: > Image 0: 1471523 Bytes = 1.4 MB > Image 1: 958712 Bytes = 936.2 kB > Verifying Checksum ...

If this is an older U-Boot, you'll need to use the cuImage.sequoia file that is produced when you compile your kernel with 'make zImage'. Sequoia (and I'm assuming you mean the AMCC Sequoia Eval Board, not some custom hardware that's based on it) has been working fine for a long time. It seems you have some kind of other uImage, so try using the one that's built with the kernel and go from there. josh
