Other Parts Discussed in Thread: CC3220SF, CC3235SF, CC3230SF
Tool/software: Code Composer Studio
I used the spislave sample code with TI-RTOS and compiled by CCSv9.2. The issue is it can send transaction.txBuf via SPI_transfer(slaveSpi, &transaction), but cannot receive transaction.rxBuf.(no any data be received). I used spimaster sample code, both of transaction.txBuf and transaction.rxBuf work well. (I used cc3235sf as SPI master connected with cc3220sf as slave last week. It has the same issue on cc3220sf that spislave sample code cannot receive transaction.rxBuf)
