Flexio_spi_ip_fault in s32k344 lpspi_flexio_ip_transfer_s32k344

[lluo]

Hi,

I am trying to run the demo project lpspi_flexio_ip_transfer_s32k344 on S32K3X4EVB-Q257 . I didn't make any change. As for the hardware connection, I followed the instruction as shown in the description.txt file. 

The code got stuck in the following line:

while (FLEXIO_SPI_IP_IDLE != Flexio_Spi_Ip_GetStatus(SLAVE_EXTERNAL_DEVICE.Instance));

I found there was a fault called Flexio_spi_ip_fault happens as shown in the attached image. Do you probably know why this happens? 

Thank you in advance.

I am also having same issue when I configure 2 FlexIOs to for SPI communication similar to the example lpspi_flexio_ip_transfer_s32k344. I am using the s32k3x4evb q172 board and have followed the instruction provided in description.txt

I also faced issues in running the SPI transfer example which has not been solved yet,

My colleague will communicate with you in your post.

Hi

Which version of S32K3 RTD are you testing?

Since you are using S32K3X4EVB-Q257, do you use Pinmatrix to connect the SPI pins as mentioned in description.txt?

Best Regards,
Robin

Hi, Robin,

Thank you for your reply. We soldered extra wires on the board as shown in the circled area in the attached screenshot. And I am using s32 design studio 3.5. The S32K RTD  that I am using is RTD 4.0.0 D2311. Today I've tried to run the demo and it is working, though I still have no idea why the fault happened yesterday.

If you encounter the problem again, please tell me how to reproduce the problem so that I can test and check the cause.
