I2C MDB out of phase

Hello NXP community,


I'm having some troubles with I2C MDB Tooldbox implementation using S32144k.


Basicaly I´m sending Write command with address 0xC8 to receive 0x08 address information from this I2C device.

I have this same implementation in S3K144K and another microcontroller.


From NXP the starting of the CLOCK is in PHASE with start of the message sent (address + data), and the I2C device do not reply to my request.


From the other microcontroller with the same implementation and same clock speed, the start of the message sent (address + data) is with 1 clock delay, and I get the information from the I2C device that I was expecting.


I have attached some pictures.


Is there any sort of way to modify/delay the message sent? For example modify low level drivers.



Thank you!
