Please refer to
https://github.com/Nuand/bladeRF/issues/955
and older issue related to same problem.
https://github.com/Nuand/bladeRF/issues/778
Setup:
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)
srsRAN_4G is latest (23.04 or 23.11)
When sample rate is changed on the fly (even if it is changed to same value), bladeRF 2.0 micro xa4 becomes unstable and gives out errors like:
command used from srsRAN_4G repo: ./lib/src/radio/test/benchmark_radio -s 11.52e6 -f 801.3e6 -t 10 -x -y
or ./lib/src/radio/test/benchmark_radio -s 1.92e6 -f 801.3e6 -t 10 -x -y
srsRAN_4G/lib/src/phy/rf/rf_soapy_imp.c Couldn't write all samples after 100 trials.
TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT
or
host/libraries/libbladeRF/src/streaming/sync.c:336] wait_for_buffer: Timed out waiting for buf_ready after 400 ms
Due to above issue, srsRAN_4G has highly intermittent behaviour in completing network attach when srsUE and srsenb used.

Re: BladeRF 2.0 micro xA4 unstability when sample rate changing
Okay, managed to solve this by manual uploading of the FPGA from python and not installing the auto FPGA loader.

Hi @failrecover,
That is a great news. Can you please share exact steps for python uploading. I don't think I have done anything like that.
I sort of bypassed the issue by having a work around in different way when using bladeRF for srsRAN_4G codebase.
Please check below link:
https://github.com/srsran/srsRAN_4G/issues/1247
But what you have done is general solution.
That would be a great help for all of us.
Regards and Cheers!!
