Dear Sir,
We use SPI interface to communicate between two TMS320F28375S CPUs.
It works fine when there is no SCI communication.
When we use SCI to send messages to PC, the SPI RX interruptr will NOT be triggered. We use scope to monitor the SPI H/W signal and can see the SPI signal is feeded into CPU.
But the RX interrupt is NOT triggered.
We check the SPI setting by CCS and they are all good. What kind of possibility will cause this kind of issue?
