Hi

We are using some TX2nx pins and cannot find the GPIO pin number to access.
Is there a way to get the GPIO # of Tx2nx pins?

  1. Is GPIO# of GPIO_12 (I2S3_dout) PC2?
  2. what is the GPIO # of below pins?
    pin name SoDIMM
    GPIO_13 228
    SPI1_CS1 97
    SPI1_MISO 108
    GPIO_07 206
    GPIO_01 118
    SPI1_MOSI 104
    GPIO_11 216
    GPIO_09 211

Thank you,

hello HuiW,

you may check developer guide for an example, To check the GPIO number.
thanks

Hi JerryChang,

Thank you for your prompt support.

The first step of the GPIO change is to search the pin in Pinmux table and gets GPIO3_PBB.00.

And tx2nx pinmux is not released, we don’t know the pins I listed applied to what GPIO.

Could you show the pins I listed applied to which GPIO?
Or could you share tx2nx pinmux?

Thank you,

Pinmux sheet is released in DLC: Jetson Download Center | NVIDIA Developer

Hi Trumany,

Thank you for your prompt support.

Plus, is TX2nx’s “value of $(BOARD)” ready for using flash command to update sdk?

sudo ./flash.sh ${BOARD} mmcblk0p1

Thank you,

hello HuiW,

it is the latest JetPack SDK release, JetPack-4.5.1 to added support for using Jetson TX2 NX module with reference carrier board included in Jetson Xavier NX Developer Kit.
you may use SDK Manager for flashing Jetson TX2 NX module on a Jetson Xavier NX Developer Kit reference carrier board.
there’s flash configure file, jetson-xavier-nx-devkit-tx2-nx.conf to enable JetPack-4.5.1 for flashing TX2 NX.
thanks
