I think I encountered a problem.
I’m using XEM3001v1 with firmware 20050622 and FrontPanel 1.2.3a.
My app continuously WriteToPipeIn() 512KB of data to the XEM (I added 2x512K SRAM) and I insert UpdateWireIns() to pause or resume the stream on the push of a button.
If I don’t use UpdateWireIns(), everything is fine but if I call UpdateWireIns() by pushing repeatedly the button, after 20 or 30 times or so, the WriteToPipeIn data on the FPGA side gets screwed up and stays that way.
I checked my app data before sending it to the FPGA to make absolutely sure the data was not corrupted before the WriteToPipeIn() call. I also checked with a logic analyzer the 512K mem data bus and found there that only the last part of the 512K block gets transferred when the system gets screwed up.
Also, if I call UpdateWireIns() but ignore it on the FPGA side, I get the same problem which leads me to think that there might be a problem with the combination WriteToPipeIn() & UpdateWireIns().
Please can you check out on your side ?
Many thanks in advance.
