I'm using M95M02 EEPROM with SPC57 MCU development board. And i've been trying to get a data out from SPI and the data seems corrupted for some reason. I used the same device with an arduino to verify and it works fine so there's no issue withe the EEPROM. I'm using the write enable instruction and i'm reading the status register. The status register should be 0x02 which i get from the arduino perfectly fine, but when I use SPC57 I get this. Same happened with ISM330DLC gyroscope. Any way I can get this fixed?0693W00000HqbFeQAJ.png

    Hello,

    the MISO is driven by the EEPROM and not by the micro.

    However, did you try to use a different pin of the micro ?

    SPI (MISO) is configurable on several pins.
