Questions for I2C pins


I’m trying the bring-up a custom board based on Xavier AGX and Jetpack 4.6.2.

For the I2C_GP3 bus (CAM_I2C), this bus is enabled by default but in the custom HW the I2Ctools are unable to read/write (only getting timeouts), something seems to be causing a problem in the lines.

For the pins in this I2C bus (F53 and E53):

Is it possible to use those pins as standard GPIOs?
Is there a way to set internal pullups resistors on those pins by modifying the device-tree?

hello greivin.fallas,

please check pinmux spreadsheets, you should have change the pinmux configuration applied by the software.
