I2c Interface

In the IMXRT 1170, we attempt to verify using i2c example code for the CM7 polling method by flashing the board directly, for instance, but with specific Cfg SDL, SDA pins on the J26 port. not receiving the clock-out signal.

I alter the pins, such as J 10 and J 09, which are cfg in the example i2c code. We are still unable to obtain a clock signal after compilation.
WHAT ARE WE TO DO

Hi @sabesh ,

Have you tested the demo lpi2c_polling using two EVK boards? One as master and one as slave.

Here are my test results, since the demo works, it proves that there are SDA/SCL signals on J26Pin10/12.
