[microblaze-uclinux] Microblaze system freeze

["Otto Blomqvist" <o2blom@xxxxxxxxx>]

Hello !

I have a multi-threaded test-application that continuously calls
setitimer / getitimer along with calls to sem_lock and sem_release. A
regular application freeze wouldn't surprise me a whole lot, but the
problem is that the entire system freezes. Ping & console are both
dead as a rock. Nothing unusual prints. It just stops, usually in the
middle, of a printf - printout. Its interesting to note that depending
on where I add printf:s in the application the application can run for
hours or minutes.

I am using the Xilinx Spartan 3E 500 Rev D development board and the
Petalogixs Xilinx EDK 9.1 reference design. Petalinux RC0.3. Xilinx EDK
9.1.02i w/ "tactical" patch.

Dhrystone tests ran for hours w/o problem so I don't think its a hardware problem...

Anyone has any hints on where to start looking ? Can I connect to the
CPU using the xps hardware debugger to see where it stopped ?

Thanks,

/Otto
