Hello 15736231627@163.com,
Hard to say, the SDK / FreeRTOS issues have been discussed a few times on the community already.
For example, you may refer to S32K142: lpi2c is not working with freeRTOS integration.
FreeRTOS module issue
We don't have such an example, unfortunately.
Can you share a test project so that we can reproduce the issue?
Do you monitor the SPI bus with a logic analyzer?
What does it mean that the program dies?
What is the return status of non-blocking function?
Thanks,
BR, Daniel
