Pinmux.dtsi & gpio.dtsi issue

Hi Sir,
I am using r36.4.3 on AGX Orin.
According to the on-line document, after pinmux.dtsi & gpio.dtsi are generated by using spreadsheet, we need to flash them into the device.

My questions:

  1. Are they included inside any dts file ? But I didn’t see any clue in flash.sh and disassembling tegra234-p3737-0000+p3701-0000-0005-nv.dtb can’t tell the difference.

  2. They don’t appear as dtbo files assigned in /boot/extlinux/extlinux.conf either.

Could you provide more information about where they are processed ?

Thanks.

Jimmy

PInmux file and gpio dtsi files are actually put as separate files under your Linux_for_Tegra/bootloader/generic/BCT directory.

Hi Wayne,
Thanks for the prompt reply.

We do know the path of these two dtsi files.
What I mean is, we would like to know how they are processed.
Are they include in some other dts file ?
Are they compiled as dtbo files ?

Somehow we didn’t find any dtb or dtbo files including the changes to pinmux & gpio, inside the device.

They are not included in any kernel dts or dtbo. They are a input file for the MB1 binary which would be handled during flash process.
