Resistors to remove on RT1160 for SPI

Hello,

I have EVK-MIMXRT1060 
I want to confirm the resistor R406 I have circled is the correct one to remove for LPSPI?

Is there a SPI loopback example (sanity type test) on this board?

Regards,
Lee.

I can confirm I got the SPI board to board transfer working.

1. I needed to use a shorter wire between the 2 boards (avoid using multiple wires joined together).
2. It worked for me using the 
evkmimxrt1160_UART_cmsis_lpspi_int_b2b_transfer_master_cm7 + slave_cm7

I have some observations which I'll raise in a different topic.

Hi @neo2,

From the SDK LPSPI project readme.txt, you also can know: 

Board settings
==============
Remove 0Ω resistors R404,R406,R408.


You need to Remove 0Ω resistors R404,R406,R408, and use two boards one as master and another as slave to test the spi code. remove the resistors, it will remove the LPSPI pins to connect to other modules.

Wish it helps you!

If you still have questions about it.

Best Regards,

kerry
