Why is the lpspi_loopback example failing?

I'm running the lpspi_loopback example program on an RT1060, and have wired together pins J24-4 and J24-5 (MISO & MOSI), but the masterRxData[] array is filled with zeroes and the test fails. Have I overlooked any configurations or settings?

Hi Alex Duh,

  Thanks for your information.

  Do you following this board settings?

Board settings
==============
Remove the resistor R334 and weld 0Ω resistor to R278,R280.

This is very important.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Best Regards,

Kerry

Hi  Alex Duh ,

   Which RT1060 code you are running now, the SDK?

  I didn't find lpspi_loopback example in the newest SDK.

So, I suggest you download the newest SDK, and test the SDK lpspi code, it works OK.

The SDK can be downloaded from this link:

Welcome | MCUXpresso SDK Builder 

Wish it helps you!

If you still have questions about it, please kindly let me know.

Best Regards,

Kerry
