We are using Nvidia TX2 SOM with L4T28.2.1.
We are facing an issue in PM I2C.
We are connecting Temperature sensor with PM I2C. We facing an I2C error while reading the temperature value at atmosphere temperature 7-8*C.
For testing purpose we have changed the temperature sensor from PM I2C to GEN I2C and tested the same. In this condition temperature sensor is working fine in (-25C to 25C).
We doubt drive strength of the PM I2C might be the reason for the issue. While surfing the datasheet we came across the registers 0X0C30202C and 0X0C302034.
We updated our results below,
Register Address 0X0C30202C 0X0C302034
Default Value 0x00F00100 0x00F00100 I2c Read error at atmosphere temperature 7-8C
Tested Value 0x00000000 0x00000000 I2c Read error at atmosphere temperature 7-8C
Can you please suggest the right value or method to increase the drive strength of PM I2C?
