Please replace the files in the necessary places:

1) mibspi_v0.c in the path: C:\ti\mmwave_mcuplus_sdk_04_04_01_02\mcu_plus_sdk_awr294x_09_00_00_15\source\drivers\mibspi\v0\mibspi_v0.c
2) mibspi_v0.syscfg.js in the path : C:\ti\mmwave_mcuplus_sdk_04_04_01_02\mcu_plus_sdk_awr294x_09_00_00_15\source\drivers\.meta\mibspi\v0\mibspi_v0.syscfg.js

Then you can rebuild the driver and the application.
