Configuring the Pinmux and GPIO

The pinmux configuration file provides pinmux and GPIO configuration information. The typical format for this data is register address and data, as a pair. MB1 allows writes to the pinmux and GPIO address range from the pinmux configuration table.

The pinmux configuration file is available at:

<top>/drive-foundation/platform-config/t23x/
automotive/bct/<board>/pinmux/tegra194-mb1-bct-pinmux-gpio-
<board>-<sku_id>-<rev>-t<a|b|c>.cfg

For example:

tegra194-mb1-bct-pinmux-gpio-e3550-0001-b01-ta.cfg

For information on converting the pinmux, GPIO, and pad DTS files to CFG format, see the Pinmux Generation Tool chapter in the NVIDIA DRIVE OS 5.1 Linux PDK Development Guide.

For definitions of the <board>-<sku_id>-<rev>-t<a|b|c>, see the Release Notes.
