You are amazing. Now it is working.

The Pins are labeled on my circuit board. From the REAR (== where the DIN rail is) the 4th PIN is MOSI and the 6th Pin is MISO.
(Sorry just saw the Pinout you linked to: KUNBUS starts their counting from the FRONT)

Noted.

Thank you very much.

So, the Con CAN option is disabled for sure. The MISO line is always high. I already double checked the connection. MISO is on the 5th pin and MOSI is on the 7th pin. I count it based on this : https://revolution.kunbus.com/tutorials/uebersicht-revpi-connect/revpi-con-module-anschliessen-connect/ He...

You mean if you directly connect MISO and MOSI as a loopback test you don't receive the same on the RevPi but on the Raspi 4? Yes that is what I mean. The TX and the RX should have the same value, with the loopback connection. I tested both with ADXL345 Or is there any way to test the spi on RevPi ...

Hi Everyone, I am trying to connect an external SPI sensor on the ConBridge. The spidev0.0 is detected on the device list. Here is the "/boot/config.txt" # For more options and information see # http://rpf.io/configtxt # Some settings may impact device functionality. See link above for det...

Hi everyone,

Nevermind, I did not read about the Watchdog. I solved it.

Thank you everyone

Is it broken or something? I have also RevPi Core3. It works perfectly fine with my current setup. Here is my ...
