SPI async comms between 2 nRF52dk boards using zephir (nRF Connect SDK v1.8.0)

Sorry this took some time, I needed to do some digging on my end. You are right, the CONFIG_SPI_1=y was no longer required as of NCS v1.7.0, so it makes sense that v1.8.0 returned this error. I also took the time to test this on my end. Using the SPI_TEST and SPIS_TEST example projects from my colleague Sigurd's Github repo available here. By making some small changes to the prj.conf files and setting the pins to available ones on my DK I was able to get two nRF52840 DKs running an SPI test as expected.

Any update? Thanks

The error only happens after adding CONFIG_SPI_1=y to prj.conf file. This is a ceteris paribus test.

Have you added this config in the Kconfig file or the prj.conf file? The CMake error seems to come from C:/v1.8.0/v1.8.0/zephyr/cmake/kconfig.cmake:270. What is located at this line?

Best regards,

Simon

Hi Simon,

Thanks for your help. Adding that line to the prj.conf file will cause the CMake script to fail:

  
  CMake Error at C:/v1.8.0/v1.8.0/zephyr/cmake/kconfig.cmake:270 (message):
    command failed with return code: 1
  Call Stack (most recent call first):

    CMakeLists.txt:27 (find_package)
  
  
  
  error: cmake failed
  create_nordic_project.py failed (1)

I could not find that option listed in the Kconfig documentation:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index-all.html

Could you check that line?

It looks like you haven't enabled the SPI 1 instance in your prj.conf. Please set CONFIG_SPI_1=y to enable this.

Best regards,

Simon
