Hi Prabhakar, > I prepared a setup on SMARC2 RZ/G3S and I can confirm it is working This is good news! > (but this is failing on SMARC RZ/G2L I'll look further into this) This not so much. Hmmm, are you verifying against the same I2C device on the carrier board? If you compare against different I2C devices on the module board, the culprit might be the I2C device. > For the SMARC2 RZ/G3S to make sure the I2C GPIO pins behave as > opendrain I have the below patch for pinctrl Do you really need this patch? The GPIO lines are wired to SCL/SDA which are already pulled up. Search for R118 in the module schematics. All the best, Wolfram
