Hi Robert (@robertghilduta ) and all, I am trying to setup srsRAN_4G ( 23.04 for srsRAN_4G) and am able to setup pretty easily with Ettus B210 using srsenb and srsue and attach does happen consistently. But same is not the case with bladeRF 2.0 micro xA4.
Below is the setup for bladerf. bladeRF-cli version: 1.8.0-git-unknown libbladeRF version: 2.4.1-git-unknown
Firmware version: 2.4.0-git-a3d5c55f FPGA version: 0.14.0 (configured by USB host)
When I try to run sudo ./lib/src/radio/test/benchmark_radio -d bladerf -s 1.92e6 -f 801.3e6 -t 10 -x -y or
sudo ./lib/src/radio/test/benchmark_radio -d bladerf -s 11.52e6 -f 801.3e6 -t 10 -x -y
Overall , It fails anyway but many times, it gets stuck to following too: [ERROR @ host/libraries/libbladeRF/src/streaming/sync.c:336] wait_for_buffer: Timed out waiting for buf_ready after 400 ms
Please do provide any solution. I even tried modifying lib/src/phy/rf/rf_soapy_imp.c to set below define constant
But that also does not make any difference.
Please do share any workarounds or fixes for same.
Issue Description
Refer to https://github.com/srsran/srsRAN_4G/issues/1247 I have been suspecting Radio interface as issue since I see very flaky and intermittent attach with bladeRF 2.0 micro XA4 with srsenb and srsue.
I thought of benchmarking and ran benchmark_radio program present in srsRAN_4G/build/lib/src/radio/test
First I did it for baldeRF 2.0 micro XA4. I see 2 number of overflows.
With same host machine, I just swapped bladerf with Ettus usrp B210 board and I don't see any overflows. Does it mean that bladeRF 2.0 micro is having some issue interfacing with srsRAN_4G? Please share your own experiences or insights.
