Dear all,
I have a problem with our USRP X410 and RFNoC. During development of an RfNoc
application, one often restarts the test program, which creates an RfNoc graph
and performs some connections on the device. However, after around 10-15
program starts, the firmware/FPGA/driver yields errors that it's not reachable
anymore. Below is a MWE yielding the error:
Test skript:
$ cat graph_error.py
import uhd
import time
if __name__ == '__main__':
time.sleep(1)
uhd.rfnoc.RfnocGraph("addr=localhost")
time.sleep(1)
print("Exiting...")
which I run in a loop directly on the USRP X410, wtih the output attached below.
$ for i in `seq 20`; do echo $i && python3 graph_error.py ; done
After the error occurs, the only way to get it back to working is to reboot the
USRP or do `systemctl restart usrp-hwd`, which interrupts the dev workflow.
My question is you can reproduce this? Is this a bug? Can I work around the
crash? If it's a bug, I should file it to the UHD github repository, right?
Thank you,
Maximilian Matthe
$ for i in `seq 20`; do echo $i && python3 graph_error.py ; done
