S32K148-Q176 FreeRTOS Lpspi Communication

[carolineliu_wiw]

Hello!

I'm working with s32k148-q176 EVB and trying to test lpspi communication based on FreeRTOS. I find the example project "freertos_s32k148". then I change its code. Altough i can build this project with no problems, the lpspi communication does not work.

Here is rots_start function in rtos.c file.

Here is my Task function.

Here is related function.

Here is the Debug window.

The varibles status_slave and status_master are equal to 2. 

2 means, lpspi transfer is status busy.

I have no idea how to solve it.

Can anyone help？

Hello,

Are you calling LPSPI_DRV_MasterInit and LPSPI_DRV_SlaveInit ?

Thanks,

I also having a problem in which LPSPI_DRV_MasterInit and LPSPI_DRV_SlaveInit  both intialized and frertos stop at default isr when masterTransferBlocking or any spi transfer function is called from the any task. since i have intialized wdog it will retart the controller every time.

Hi,

Maybe you can try to reset the interrupts priority of SPI.
