Why some pins should have GPIO function but not marked in TX2 pinmux document?

Dear JDSchroeder,
Thanks a lot.

We will have a try.

Dear JDSchroeder,

The Jetson-TX2i-TX2-4GB-Template wasn’t updated in Jetson-TX2-Series-Pinmux-Template-v101.zip. Could you also update it? Our product uses TX2-4GB module.

Dear JerryChang,

Thanks for your explanation.
I am still not clear about the difference between pinmux_config(tegra186-mb1-bct-pinmux-quill-p3310-1000-c03.cfg) and bootloader_dtb(tegra186-quill-p3310-1000-c03-00-base.dtb). I know some pin can configure by either pinmux_config or bootloader_dtb, which file finally make sense?

I generate a tegra18x-jetson-tx2-config-template-gpio-default.dtsi file, but how could I make this dtsi configuration work? I have tried many method, but seem not work.

Hi JDSchroeder,

Please help us update the pinmux document of tx2-4G.

hello garretzou,

you’ll need to check Jetson TX2 Boot Flow for reference,
in short, bootloader (MB1) load the cfg file for firmware initialization.
dtb file were loaded while kernel initialize, it’ll also overwrite several configurations.
thanks
