Re: [partial-reconfig] Reg uclinux/microblaze and partial reconf.

Hello John!
Thanks for your reply.
I have read your paper long back while digging for inputs on
reconfiguration. It really is an interesting read.

I have some experience with linux in general and I could visualize
how things could be done. I would have written a char device driver
and internally parse the inputs and call the ICAP APIs accordingly.
I think it shouldnt be difficult.

But currently I am way behind this. I have EDK 6.3 and I do not
have an option to build uclinux under software settings for
microblaze. So, is there anyway that one could build a uclinux
for microblaze with EDK 6.3 version?

Thanks
LN
