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

[Rick Hunnicutt <RHunnicutt@xxxxxxxxxxx>]

Further information on this... The heartbeat function shows the kernel is running. I can manually output data to the uart through the xmd console. 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.

Again, any ideas or help would be appreciated.

Thanks,
Rick
