Hello,

We are trying to use the project example "lpi2c_master_s32k144" and we can not see the i2c signal with the oscilloscope in this line.

We are using an external pull-up for the scl and sda connected to 3.3 volts. 

We tried also with 5 volts.

Thanks in advance.

Hello @adrimen3668,

The J2.19, J2.20 are not routed to PTA2/PTA3 by default.

Use J1.1, J1.3 instead.
