Why is the lpspi_loopback example failing?

alex_duh — Tue, 18 Aug 2020 20:43:38 GMT

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 ,

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
