Hi guys,
I've been trying to follow the 2.6 port howto found at
http://www.embeddedarm.com/software/arm-linux-26-ts72xx.php
The guide states this should be portable to the 7400 also.
I managed to compile the kernel without much fuss, and attempted a
bootload from my old 2.4 kernel.
However when I try to boot I get problems with what looks like an
incorrect IRQ configuration, and it's trying to force 7250 filesystems
despite my kernel commandline specifying an nfs mount.
dmesg:
Creating 3 MTD partitions on "ts7250-nand":

Can anyone help me dissect the problem? I'm not really sure where to
begin.
ambro915, if you're reading this, does your 2.6.24 patch solve this?
