SYSFS GPIO Number of ORIN NANO gpio PCC.03, PX.07 Question

Hello,

I’m developing a camera with Jetson, but I’m using gpio for ZOOM control when controlling the autofocus motor, but I don’t know the sysfs gpio number, so I’m trying to ask a question.

ORIN NANO ZOOM A+ (No PIN Header #)
Jetson NANO used GPIO06, and the SYSFS GPIO number indicated on the PIN MUX Excel Sheet was PI.00, and number 64 was used according to GPIO3_PI.00 = 8(I) * 8 + 0(00) = 64
ORIN NANO uses PCC.03, through which you need to interrogate the SYSFS GPIO number.
ORIN NANO ZOOM A- (No PIN Header #)
Jetson NANO uses UART0_CTS, and the SYSFS GPIO number shown on the PIN MUX Excel Sheet is PD.04, and according to GPIO3_PI.00 = GPIO3_PD.04 = 3(D) * 8 + 4(04) = 28, 28 should be used.
ORIN NANO used PX.07, through which you need to interrogate the SYSFS GPIO number.

When I looked for the Jetson Orin NX, Nano pinmux config template Excel file, it was as follows.
ORIN NANO ZOOM A+ uses PCC.03, and I need to know the SYSFS GPIO number corresponding to it. What is the SYSFS GPIO number for PCC.03?

ORIN NANO ZOOM A- uses PX.07, and I need to know the SYSFS GPIO number corresponding to it. What is the SYSFS GPIO number for PX.07?


Thank you.

Hi yhlee1,

You could refer to the following instruction for the calculation of GPIO number in sysfs.
