Hi Marcus,
I have tried setting the tx_subdev "A:0 B:0 A:0 B:0" probably you mean only
"A:0 B:0" since it produce another error saying input port already
connected. I have tried another several benchmark configuration as follow:
1. ./benchmark_rate --tx_rate "1e6" --args "addr=192.168.40.2" --tx_subdev
"A:0 B:0" --channel "0,1" or ./benchmark_rate --tx_rate "1e6" --args
"addr=192.168.50.2" --tx_subdev "A:0 B:0" --channel "0,1" --> result
success with 0 error
2. ./benchmark_rate --tx_rate "1e6" --args "addr0=192.168.40.2,
addr1=192.168.50.2" --tx_subdev "A:0 B:0 A:0 B:0" --channel "0,1,2,3" --ref
"external" --pps "external" --> produce error Error: RuntimeError: On node
0/DmaFIFO_0, input port 0 is already connected.
3. ./benchmark_rate --tx_rate "1e6" --args "addr0=192.168.40.2,
addr1=192.168.50.2" --tx_subdev "A:0 B:0" --channel "0,1,2,3" --ref
"external" --pps "external"--> only 2 out of 4 red LED is On for a few
second, and the benchmark rate freeze at [00:00:06.374504] Testing transmit
rate 1.000000 Msps on 4 channels.
4. ./benchmark_rate --tx_rate "1e6" --args "addr0=192.168.40.2,
addr1=192.168.50.2" --tx_subdev "A:0 B:0" --channel "0,1" --ref "external"
--pps "external"--> only 1 out of 2 red LED is On for a few second, and the
benchmark rate freeze at [00:00:06.374504] Testing transmit rate 1.000000
Msps on 4 channels.
When i change -tx_rate in all the 4 test into --rx_rate. They work pretty
well and not produce any error. It seems the problem only come when i try
to create multi usrp object and it only happen during TX only. Even in
fourth test i only use channel 0 & 1 which in only exist in first USRP, the
problem still occurs. All the error after the freeze creates error message
saying BIST failed (code:1) if i try to re run the benchmark test, and i
have to turn on and of the power of the USRP.
Do you have any idea why it could happen? I have configure the cpufreq-info
and net.core.rmem_max & wmem_max to 50000000 and sudo ethtool -G tx 4078 rx
4078 to both usrp interface to no avail. What confuse me is why it is only
happen during TX, while the RX is doing fine. I attach the benchmark test
run output below until the freeze occurs.
Thank you for your respond
Regards,
Harfan
