SHT3x sensor not responding on Xavier NX

installed sht3x i2c sensor on board. created dts entry and loaded driver in kernel, (i2c@c240000)

i2cdetect sees nothing at i2c1 (0x44), the driver bails out with -121 in other words the board behaves as if the sensor did not exist at all.

i2c debugger sees i2c packets but they are all address NAKs

Any clue greatly appreciated. kernel is 5.10.192.
Older versions of our software running in 4.9 could reach the device by simply writing to /dev/i2c-1 with device 0x44

If device NAKs that tell the HW problem. It could be the power/reset … for the device.

Thanks
