I have an Orin AGX 64GB Developer Kit. Using the Jetson.GPIO library I am able to control only some of the GPIOs.
Specifically, the GPIOs that are connected through the TI TXB0108 level translators on the carrier board are stuck at 1.6V (though they do wiggle by a few mV when I toggle the signals in SW).
The GPIOs that are connected directly to the SoC and those connected through the SN74LVC4T245 buffer are controllable through SW just fine.
I am referring to the notes related to Table 3-4 - (40-Pin Expansion Header Pin Description) in the document - NVIDIA Jetson AGX Orin Developer Kit
Carrier Board Specification - SP-10900-001_v1.0.
Would appreciate any help. Are there any HW jumpers that I need to select on the board to get these signals to work? (like in the Xavier AGX).
