Re: [microblaze-uclinux] [patch] Ethernet driver update

[John Williams <jwilliams@xxxxxxxxxxxxxx>]

Hi Hector,

I am not aware of any issues with the current toolchain and most recent
uClinux.org sources.  If you can provide more details of the problems
you are having, we might be able to help.

On a related not, PetaLogix will soon be releasing a bundled source
tree, tools and development environment, that solves exactly this sort
of problem.  More details soon.

Regards,

John
