LAUNCHXL-F28379D: LAUNCHXL-F28379D: SPI communication between two f28379D launchpads

hi everyone

I am a beginner in the CCS area and I need help. I am trying to communicate between two f28379D launchpads with SPI. I want to send data from master to slave. However, the problem is coming. Everything is great in the master. I observed the waveform in the master with an oscilloscope. 

but I am unable to receive the data on the slave side.
