I am using S32K311 for my project.
I have configured LPSPI0 as Master to use with a Slave.
Pins

Peripherals

Port - configured with no issues

Model: Reused example model SPI Asynchronous Interrupt Transfer S32CT, modified so that an LED Blinks after a successful job instead.

This is what's inside the Initialize Block

There were issues building the model with regards to Lpspi_Ip_LPSPI_1_IRQHandler and Lpspi_Ip_LPSPI_2_IRQHandler.
I disabled those interrupts and enabled for LPSPI0 in S32CT - Platform component

Then I was able to build with no issues, but when I flashed the program, I don't see expected output. I previously used S32K312 EVB and was able to check data being sent on the scope but now, I only see a solid 5V going out on MOSI line.
Attached the mex file below.
Please let me know what other steps I might be missing. Let me know if you need any additional info.
Also, I am a new user of S32CT and if there are any resources to understand the S32CT in a detailed and better way, that would be very helpful.
Thank you!
