RE: [microblaze-uclinux] RE: Problem with Petalinux booting with lltemac
Thanks Michal. The version is off the development branch pulled Nov 25th. It is the non-MMU version. The kernel boot log is as follows:

Running local start scripts.
It delays for several seconds before the final 'u' is printed and that is all I get. I put a printk in the heartbeat function just to check the serial output and it does continue to print where before it didn't seem to do so. I've noticed the printk's don't seem to use the uartlite driver while these last messages do.
We did use a reference board and did not have this issue. The main difference is the custom board uses the 1000Base-x PHY and the reference board (Avnet Lxt PCIe) uses a MII based PHY. As previously mentioned, if I remove the temac from the hardware project, the kernel boots fine, I can log on, and it is stable.
