MISO on oscilloscope is correct but value in the receive buffer is wrong

Hi,

I use the nRF52832 with SDK14 and no softdevice.

The MISO on oscilloscope is correct but value in the receive buffer is wrong (can be any value). Unfortunately I cannot measure directly on the nRF52832 pin, so I measured on the sensor MISO pin but the track get split in between thus I cannot know if the path is damaged.

Thus I tried to drive with the nRF52 the MISO pin high. I did it before the SPI and the sensors are initialized. I measured only 0.2V when high and 0Vwhen low.

Do you think the MISO port on the nRF52 is somehow broken?

Thanks

Hi,

Do you have some schematic that shows how this path looks like?
