WARP Project Forums - Wireless Open-Access Research Platform

I have a couple of hardware problems with the WARP nodes I'm working on. Can you please help direct me to the right resource for getting it fixed?

1. One of the node has its ERR led light in "FPGA Config" constantly on. This happens regardless of the bitstream I program the node with via SD card. However, the node appears to be functional. The same bitstream works fine with other nodes with the green light on `STAT`. Is there a problem with this node's CPLD?

2. Another node, after a series of late night experiments, can no longer be configured via SD card. When I turn it on with the SD card plugged in, the configuration process does not start. And if I power cycle the node using the ON/OFF switch, the fan doesn't come up as well. I have to disconnect / reconnect the power cable to get the fan going again. One last thing I tried was to reprogram the CPLD with the provided bitstream in the WARP repository. However, impact could no longer recognize the CPLD chip:

Is hardware fix now needed for both of the nodes? Is there anything else I can try to help diagnose the problem?
