S32K342 - LSPI timeout issue

[Indumathi]

Hello Team,

Greetings!!!

We are using LSPI2 and LSPI3 as master for our project.

1. It is observed that when the communication is initiated from LSPI0 due to timeout, the SPI  module module API is returning faulty status. 

2. The registers CR, CFGR1, CCR, CCR1 are not having correct value which is causing issue as well. Attached the screenshot of the registers 

could you please check and let us know what is the issue.

Thanks and Regards,

Indumathi

Hi Indumathi,

I saw that LPSPI0 is configuring to use DMA request.

So, you will need to configure for this, as below:

In Mcl:

In Platform:

I assume that the issue come from interrupt handler of LPSIP0 wasn't handled.

Best regards,

Nhi

Hello Team,

Thanks for tin debugger it is not as expected. it is showing all zeros.

he reply. We are using S32K342 controller and Greenhills compiler. As part of application requirement we have configured LSPI2 as master to connect with external device PMIC. We are using RTD 2.0.0 package.

1. as part of communication the timeout is happening and communication is not initiated.

2. when debugged further it is observed that the registers of LSPI2 module are not updated properly as expected by the program.

Please hep to understand and resolve this issue.

Attaching the EB project configurations for the reference.

Thanks and Regards,
