Setup Details

last compiled version of Srsran 23.10.1 Benetel 1.0.4

Srsran Config:

is_prach_cp_enabled: 1               
compr_method_ul: bfp                  
compr_bitwidth_ul: 9                  
compr_method_dl: bfp                  
compr_bitwidth_dl: 9                  
compr_method_prach: bfp
compr_bitwidth_prach: 9

Benetel Config: short Sequence for Prach. short Sequence Compression: both are trialed. static_compressed O-RU expects O-DU will send the C,U Plane packets without udCompHdr and BFP9 compressed dynamic_compressed O-RU expects O-DU will send the C,U Plane packets with udCompHdr and BFP9 compressed

Actual Behaviour

Srsran Exited with below Error:

/home/accelleran/srsRAN_Project/lib/ofh/receiver/../support/prach_context_repository.h:121: void srsran::ofh::prach_context::write_iq(unsigned int, unsigned int, unsigned int, srsran::span<const std::complex<float> >):                                                                                        
Assertion `symbol < nof_symbols' failed - Invalid symbol index.                                       
Aborted

Steps to reproduce the problem

setting Srsran and Benetel with above settings.
