Hello Jade,

You are welcome.

''Using another twim, it isn't possible that the I2C communication works with this pinout configuration ?''

It is not possible to use Port2 for TWIM on nRF54L15. The hardware simply does not route any TWIM instance to port2. You can look at this block diagram

This means that TWIM20-TWIM22 can be assigned pins on GPIO port P1, TWIM30 can be assigned pins on GPIO port P0.

Hello,

Thank you very much for your answer!
In fact, this is a pin of a FPC connector to connect to a digital board and it is a custom board so we choose to connect the SDA at the pin 02.01.

Using another twim, it isn't possible that the I2C communication works with this pinout configuration ?

Thank you !

Best regards,

Jade

Hello,

Fatal error -5 is most likely related to your pin mapping. You have assigned P2.01 for SDA.

You have to correct this pin.

Thanks.
