Thanks John.
The temac driver is not in the kernel and I'm still experiencing these
problems.
Setting the system to boot in single mode – I got the shell prompt but it
would not respond:
So let me get this straight, your core platform without TEMAC HW is fine?
However, as soon as you add the TEMAC, even without enabling the kernel driver,
you get instability and crashing? Strange.
If you can send your MHS file I'll take a quick look, but also you should check
your HW synthesis / P&R logs for timing constraint violations, something
like that.
Also maybe check for any pins with no LOC constraint, the tools assign unLOC'd
pins randomly and this can sometimes do strange things on the board, maybe
enough to trash your microblaze system.

[microblaze-uclinux] RE: Problem with Petalinux booting with lltemac
Just for completeness, what
happens if you leave the ll_temac in the HW project, but just don't enable the
kernel driver?
Also, with the temac HW and driver enabled, try adding "single" to
the kernel commandline in uboot before booting. It will boot to single
user mode (just a shell) without running init. Is it stable? You
can then manually run the commands in /etc/rc, and the scripts in /etc/rc.d/S*.
See where in that oprocess the instability is introduced.
You might also want to pepper the temac driver with printks, particularly the
phy_setup() function, see if you can associate a particular action in the
driver with the lockup.
Regards,
John
