I would suggest getting using uClinux-dist-20060803 and getting the
arm-linux toolchain at
http://ftp.snapgear.org/pub/snapgear/tools/arm-linux/arm-linux-tools-20061213.tar.gz
and then compile for the gdb/ARMulator target.

I doubt any otehr ARM7TDMI targets with 2.6 kernels work in there.

If you really want a 2.6.19 kernel I would suggest starting with
uClinux-dist-test-20061215.

Regards
Greg
