Sorry, I forgot to press enter between the uploads, and the naming wasn't too good either, but spi_test.zip should contain the SPI master:

Thanks Simon

I do not see the master side, but only the salve in this example.

The reason I linked to the sample samples/sensor/adxl362, is because it seems to use SPI CS and the SPI driver. It may seem like the sample doesn't use the SPI driver, is because it is not the top layer, however if you look at the image under NCS Tutorial part 3-->Use the sensor drivers-->How it works-->The call stack, you can see that it does.

However, a colleague just made an SPIM sample using SPI CS, he made an SPIS sample as well that you could test it with. I'll upload both.

Hi Simon,

How don't know how this sample helps me. This sample based on a different driver not SPI.

My claim is that SPI CS is not working in version 1.41 but it is working in version 1.3.1.

I don't have any sensors with SPI at hand right now that I can test with, but have you looked at the sensor samples in ncs\v1.4.1\zephyr\samples\sensor, and use them as a reference how to go about it. E.g. look at samples/sensor/adxl362, which comes with an nrf52832dk overlay file as well.

Best regards,

Simon

Aah, okay. I was too quick. I'll look into it.

Hi Simon

Thanks for your reply.

The loopback application is working. I already tested it in the past. This simple application uses MISO and MOSI lines only.

It does not use GPIO as CS line. The problem is with the CS line as I wrote in my original ticket.

I just tested an SPI loopback example in NCS v1.4.1 using SPI3 and nRF91 DK. It worked without problems, can you test it out and see if it works for you?
