Xavier nx i2c not working on 5.0.2

[ufukasill]

hello everyone.

i want to do pan tilt camera on xavier nx with 5.0.2 jp
i installed library with perfecly and i tried my servo pan tilt set on jetson nano
there is no problem at the moment
but i tried on xavier nx not working.
for example code giving same as jetson nano but there is no any action on pan tilt set

i think doesnt work any i2c module because xavier dont connect any i2c module.
gpio pins not working on 5.0.1 DP on the past. i waited 5.0.2.
now gpio working and gpio blinking led.

how can i do. this is so important for me !

hello ufukasill,

how you setup the connections to give the power supply?
are you using correct i2c bus, please double check the hardware connections.
thanks

hello ufukasill,

may I know which pin on Xavier NX you’re used to communicate with this device?
please also access Jetson Xavier NX Product Design Guide, and please refer to [Figure 12-1. I2C Connections].
