Runtime error in perf_host #31

Closed surangamh closed 1 year ago

surangamh commented 1 year ago

I built the perf_host design for U280. I could generate the bitstream, program the alveo, and load the driver. However, I got the following error when I tried to run the sw executable.

Number of regions: 3 Hugepages: 0 Mapped pages: 1 Number of allocated pages: 8 Number of repetitions: 100 Starting transfer size: 128 Ending transfer size: 32768 terminate called after throwing an instance of 'std::runtime_error' what(): cProcess could not be obtained, vfid: 0 Aborted (core dumped)

Any thoughts on how to debug? Thanks!

lol, just $ sudo ./main

@yluo39github Thanks. Actually, the issue was that I didn't warm boot the machine after programming the bitstream.
