How to update tegra19x-mb1-pinmux-p3668-a01.cfg alone for NX

Dear NV_Team,

How to flash NX pinmux configuration file tegra19x-mb1-pinmux-p3668-a01.cfg alone? Not to flash the whole image of NX(sudo ./ -r jetson-xavier-nx-devkit-emmc mmcblk0p1).

hello Ciya.Jiang,

you cannot flash pinmux configuration file alone, please perform whole flash to update board configuration with cfg file.
