Board crashes when using Epiphany

Postby JamesHarrison » Fri Jun 27, 2014 11:16 am

Bit of a blocker as you might imagine...

Basically board boots and is stable. Using an AB Open open case with a fan and heatsinks on Epiphany and Zynq chips. I'm using the headless (no HDMI) bitstream and the Ubuntu image.

If I try and run anything from the epiphany-examples or parallella-examples folders the board freezes instantly. Only a reboot brings it back. There's nothing obvious in the logfiles.

Any ideas or did I just get a broken board? And if I did, what's the process to get a replacement?

Could you perhaps try with the HDMI FPGA bitstream and kernel. No reason why this should work better than headless that I can think of, but worth a try.

Which examples are you using? And what is your ssh/Xserver/vnc set up?
Most of the examples - especially the really interesting ones! - cannot be run on a headless build because they use the frame buffer. :cry:
So you're limited in choice as far as the examples go.

I'm using shodruck's headless nano build .
Xtemp works over ssh/Xserver - I'm using MobaXterm Personal Edition on Win 7.

I've tried a bunch of examples - I've also tried with the hdmi bitstream+kernel and it breaks too. Guessing it's RMA time?
