bad file: config.yaml

[hdtuanss]

Hi,

Thank you for your nice work.

I'm running NR-Scope in Ubuntu 22.04 together with USRP B210 and having this issue:

~/NR-Scope/build$ sudo ./nrscope/src/nrscan
Active RF plugins: libsrsran_rf_uhd.so libsrsran_rf_zmq.so
Inactive RF plugins:
terminate called after throwing an instance of 'YAML::BadFile'
  what():  bad file: config.yaml
Aborted

This is the config file in nrscope/src

Could you please take a look?

Thank you.

Hi, could you run at build/nrscope/src, and if you are not using an external clock, could you just set rf_args: "type=b200" in config.yaml (i.e., remove clock=internal)?

Hi,
I ran at build/nrscope/src and it worked.

Thank you!

Thanks for trying our tool! As a complement to Xuyang's response, I have the following comments.
In the CMakeLists.txt in the root directory, there are two lines of code that will copy the config.yaml file from /nrscope/config/ to the build directory, when you run the make command:

configure_file(${PROJECT_SOURCE_DIR}/nrscope/config/config.yaml
${CMAKE_CURRENT_BINARY_DIR}/nrscope/src/config.yaml)

So you can edit your config file at /nrscope/config/ and run make again to apply the new changes to the build directory. The code will try to search config.yaml in the directory that you run the nrscope command, so either copy the config file to where you want to run the command or just run the command at build/nrscope/src.

Thank you for your answer, it can run well now
