Re: [microblaze-uclinux] RE: Problem with Petalinux booting with lltemac

[Michal Simek <monstr@xxxxxxxxx>]

Hi Rick,

it is hard for us to help you.
Please post more relevant information like
Petalinux version?
MMU/noMMU
kernel log

If you see heartbeat you use any noMMU a little bit changed version.

Do you use any ref board? Do you have the same problem on it too?

Regards,
Michal

I thought maybe this was similar to the uart lite hanging that Olof was working through. I put the CONFIG_HZ param up to 200 then 300 but still the same results (besides very fast blinking LED's). Since the prints aren't working, my debugging efforts are crippled.
