linux hung when using pcap to program PL

sqf09fd

Hi,

 

I'm running Ubuntu 16.04 with linux kernel 4.14.0 on zedboard. All my boot files are generated on version 2018.1. I'm trying to use PCAP within ubuntu.

 

My problem is that every time I try to use pcap in linux (echo bitstream.bin > /sys/class/fpag_manager/fpag0/firmware), I can see the program led went blue, indicating the bitstream is programmed successfully, but meanwhile the system would also cease to function immediately.

 

I wonder if anyone here has encountered the same issue before. Does anyone has any clue of how to solve this?

 

Thanks,

Clark
