Saturday Frights and Sunday Lights/Kernel Building for the BBAI-64

Hello…Me Again and Again,

Um, I see a file in some directory that I keep coming across: k3-j721e-beagleboneai64-pinmux.dtsi.

That .dtsi file is the file I am discussing. From what I understand, I was thinking that maybe some files would be available for peripheral access.

Can I look to that file in the future for peripheral access like GPIO, I2C, and/or PWM?

I am trying to only access i2c, gpio, and pwm.

I know everyone has their sights on building and people are busy. I completely understand. This is why I keep reaching out in case someone sees this pleading for access.

BONE_PIN(P8_10, default, P8_10(PIN_INPUT, 7)) is the GPIO needed and I can change it (so I think) to O instead of I.

I2C2 will be needed and is available. I saw it already ready for consuming.

P.S. I do not understand u-boot and the build of arm64 with regards to u-boot either. Are there some scripts to view that are directed at the firmware and/or u-boot building for arm64?
