Pinmux-dts2cfg.py errors with default pinmux

[rgalliath]

When using the default pinmux spreadsheet (V1.08) to generate a pinmux configuration for a TX2i I get the following errors when running pinmux-dts2cf.py.

python pinmux-dts2cfg.py --pinmux addr_info.txt gpio_addr_info.txt por_val.txt --mandatory_pinmux_file mandatory_pinmux.txt tegra18x-jetson-default-template-pinmux.dtsi tegra18x-jetson-default-template-gpio-default.dtsi 1.0 > ../../../bootloader/t186ref/BCT/tegra186-mb1-bct-pinmux-quill-p3489-1000-a00.cfg

hello rgalliath ,

please check the readme file, you should remove --mandatory_pinmux_file options for confirmation.
thanks

Hi Jerry,

Thanks that worked. Could you explain what the purpose of the mandatory_pinmux.txt file is? All the readme says is:

Mandatory pinmux information file entry should follow below format for an entry.

If we are not supposed to be using this option, why is it included in the Adaptation and Bring-Up guide?

hello rgalliath,

it’s an information for PinMux configuration for the bring-up process.
the mandatory (must have) configurations will be like hardcoded, such that mandatory configurations cannot be changed.
for example, this mandatory configurations used specific for IOs in PinMux configurations, such as I2C SCL/SDA pins should be in input enable mode.
thanks
