Hello, I am configuring the pinmux spreadsheet, but I have encountered a problem and need your help，thank you!
I don’t know the configuration principles of “Customer Usage”, “Pin Direction”, “Req. Initial State”, “LPDR Enable”, and “Req. Deep Sleep State”. Where can I find them？
hello Yolomei,
this depends-on your own design purpose, it’s the pin configuration of mb1-bct.
hello Yolomei,
those pin were default defined as GPIO, so, you’ll need to click the button on top-right to [Generate DT File] after customization.
you should copy those generated dtsi file to JetPack installation path,
for example,
~/nvidia/nvidia_sdk/JetPack_<version>_Linux_<platform>/Linux_for_Tegra/
and…
you should see python file, $OUT/Linux_for_Tegra/kernel/pinmux/t186/pinmux-dts2cfg.py it is used to convert them into cfg format.
after that,
please have full flashing to update the board configuration.
please see-also developer guide, Pinmux Changes for reference,
thanks
what you really want to check?
this is I2C7_CLK instead of audio pins you’re mentioned in comment #4.
please check TX2 TRM for [8.31.7 PADCTL Audio Registers].
Yes, this is a problem I accidentally saw after configuring the audio, so please ask.
Theoretically, shouldn’t the register values I see be consistent with those in the cfg file.
hello Yolomei,
cfg file is the init settings, it’s able to alter by kernel controls.
How do you use this command? I don’t quite understand. If you refresh completely, you should use the following command：
sudo ./flash.sh jetson-tx2 mmcblk0p1
hello Yolomei,
please see-also developer guide, Pinmux Changes for reference,
it’s python script file, pinmux-dts2cfg.py to convert dtsi into cfg file format for image flashing.
So I can only use the following command to permanently refresh the pinmux file
sudo ./flash.sh jetson-tx2 mmcblk0p1
hello Yolomei,
that’s correct. you must perform full flash to update the cfg file
Ok, thank you!!
