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 about converting the pinmux, GPIO, and pad DTS files to CFG format, see the Pinmux Generation Tool section in the NVIDIA DRIVE OS6.0 Linux PDK Developer Guide.

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