S32K146EVB Board LPI2C unable to Test

[Nibesh]

Hello @VaneB I am unable to test LPI2C Example code.
I have checked the datasheet, the PTA2 and PTA3 pin is not connected (DNP).
So do I have to short with 0ohms Resistor.

Hi @Nibesh 

Which software are you using (SDK or RTDs)?

Hello @VaneB 
I am testing both RTM and S32DS Example Code.
I am using S32Design Studio IDE for it..

Hi @Nibesh 

Some hardware changes are required to run the LPI2C SLAVE/MASTER example. 

R146 (PTC0) and R147(PTA6) are placed by default, remove and place R544 (PTE11) and R543 (PTE10) for I2C functionality with FLEXIO or R542 (PTA2) and R541 (PTA3) for LPI2C. Also, it is mentioned in the examples documentation that two pull-up resistors should be connected, one between VCC(J3.7) and SDA pin(J1.1) and the second one between VCC(J3.7) and SCL pin(J1.4).

Please make the HW changes according to any of the mentioned options.

Note: the first HW recommendations are based on the following schematic: S32K146EVB-Q144 Evaluation Board Schematics.
