ICM-42670P error code -12

Hi

I am during PCBA testing on a board with ICM42670P, where i firstly verified the circuit and fw on a eval kit, but now i am testing on the final PCB, where i don't have access to the SPI connection.

I am using a ICM-42670P connected to a PSOC 6, using 4-wire spi, and I am powering VDD with 3.3V and VDDIO with 3.13V. When debugging the test code I always get 0xff when i try to read a register, which leads to a error code -12 (based of the driver example here: https://github.com/tdk-invn-oss/motion.arduino.ICM42670P/tree/main/src

Then i notice that the eval kit (DK-42760-P) has a pull-down on the MISO line, but all other spi lines where also pulled up. I tried to mimic that on my setup, but that didn't change a think.

Any helps or hints are highly appriciated.

Thanks.
