We are Using MQX RTOS for our custom board based on MK60DN512ZLVQ10 series of Kinetis ARM Cortex-M MCUs. We have developed our application based on MQX 3.7 RTOS for our custom board and its working fine But we need to migrate from MQX3.7 to MQX 18.104.22.168. We have ported from MQX3.7 to MQX 22.214.171.124 and our application to MQX 126.96.36.199.
We are facing issue with the SPI communication.
There are 3 devices on the SPI channels and two are working fine.
For the third device, the Receive FIFO Drain Flag never seems to set on receiving the byte from the slave device. I am able to see the received byte in the RXFRn registers.
Our code is working fine on the MQX3.7 but is facing problems on MQX 188.8.131.52.
Can you please suggest any ideas due to which we might be facing this problem?
