Hi Blair010,
What’s the Jetpack version in use?
How do you configure it in pinmux spreadsheet?
Except for configuring it as GPIO3_PP.00 in “Customer Usage”, do you also configure it as Input/Int PD for your use case?
Jetson.GPIO is designed for 40-pins header, but you also can customize it for your use case.
e.g. if you want to add the support for PP.00, please try to configure it as following.
JETSON_ORIN_NX_PIN_DEFS = [
+ (92, 'PP.00', "tegra234-gpio", 41, 28, 'CAM0_MCLK', 'GP52_CLK1', None, None),
(144, 'PAC.06', "tegra234-gpio", 7, 4, 'GPIO09', 'GP167', None, None),
(112, 'PR.04', "tegra234-gpio", 11, 17, 'UART1_RTS', 'GP72_UART1_RTS_N', None, None),
