Has anybody had experience with the Xilinx virtex4 port with apu fpu.
I’m trying to make it work now. (the apu fpu port)
As long as I deal with the "usual" tasks all working fine.
When I introduce the floating tasks the system just freezes.
All tasks are created with success but when the scheduler is trying to run the first task all freezes.
I am working with virtex4 fpga but on a customized board (not evaluation ml410).
Also I ported the project from xilinx edk 8.2 to 9.2.02i and running it from there.
When I run simple float multiplication without multitasking it succeeds.
Xilinx errata on the ppc405 mentions system freeze : http://www.xilinx.com/support/answers/14052.htm
But I’m not sure if I encounter one of their scenarios.
Any suggestions ?
