I2C Module Sends 3 times the address

Hi NXP Team,

I'm developing a custom board using S32K358 on MBDT.

I want to establish an I2C communication between the ECU (Master) and a slave device (such EE).

When i use this block to read some bytes on EE

I found out with the oscilloscope that it sends 3 times the SlaveAddress... after that the eeprom responds with its byte but on free master the variable master_i2c_recv is always 0.. so i don't really know if it's working properly.

 

What could be the problem? Is it correct that the block sends 3 times the slave address?

 

Thanks,

Simon
