*** Please note that this reply is generated by LLM automatically ***
Based on the provided context, the question appears to be asking about the Module Pin 513 on the Jetson Orin Nano Developer Kit Carrier Board Specification (SP-11324-001_v1.3) and its relation to the M.2 Key E Expansion Slot (J10) Module Pin 128, which is labeled as GPIO5 WiFi Disable GPIO.
From the context, we can see that the Jetson Orin Nano carrier board includes a M.2, Key E Slot Mini-PCIe Expansion slot (J10) that provides interface options for WiFi/BT, including PCIe (x1), USB 2.0, UART, I2S, and I2C optional.
The Module Pin 128 on the M.2 Key E Expansion Slot (J10) is labeled as GPIO5 WiFi Disable GPIO. This suggests that this pin is used to control the WiFi functionality on the M.2 module.
On the other hand, the command cat /sys/kernel/debug/gpio shows that GPIO316 to GPIO511 are available on the system. However, there is no direct information about Module Pin 513 in the provided context.
It is possible that Module Pin 513 is not a valid pin on the Jetson Orin Nano Developer Kit Carrier Board Specification (SP-11324-001_v1.3). The pin numbering on the carrier board may not match the GPIO numbering on the system.
In comparison, the M.2 Key E Expansion Slot (J10) Module Pin 128 is a valid pin that is used to control the WiFi functionality on the M.2 module. However, without more information about Module Pin 513, it is difficult to determine its exact function or relation to the M.2 Key E Expansion Slot (J10) Module Pin 128.
In summary, the M.2 Key E Expansion Slot (J10) Module Pin 128 is used to control the WiFi functionality on the M.2 module, while the information about Module Pin 513 is not available in the provided context.

Hi boxletters,
Are you using the devkit or custom board for Orin Nano?
What’s the Jetpack version in use? Jetpack 5.1.3?
Sorry that I’m not clear about your question here.
Do you want to get the pin state for the following GPIO?
If so, you can either measuring it from scope or reading it through sysfs.
Orin Nano ，Jetpack 5.1.3，
how to read it through sysfs.
cat /sys/kernel/debug/gpio,
it give gpio-316～gpio-511，
but not gpio128
i want to get M.2 Key E Expansion Slot for wifi module
Module Pin 128 GPIO5 Wi-Fi Disable
i try to use another Orin Nano developer kit
wifi work well
i use intel ax200 to replace rtl8822ce ,ax200 also work
So I want to know which WiFi module do you suggest for Orin Nano developer kit whether Jetpack 5.1.3 or not Jetpack 6.2.1,where can I find the WiFi module list for recommended about Orin Nano developer kit
Please run the following command to check its gpio number first.
# cat /sys/kernel/debug/gpio|grep PCC.02
gpio-330 (PCC.02 )
Then, you can run the following command to export this pin and check its state
# echo 330 > /sys/class/gpio/export
# cat > /sys/class/gpio/PCC.02/direction
# cat > /sys/class/gpio/PCC.02/value
When I excute sudo echo 330 > /sys/class/gpio/export
It return /sys/class/gpio/export:permission denied.

login as root user and try execute
Please run sudo su first.

128 GPIO5 GPIO5
it also give the same answer
but cat /sys/kernel/debug/gpio
gpiochip1: GPIOs 316-347, parent: platform/c2f0000.gpio, tegra234-gpio-aon:
gpio-316 (PAA.00 )
gpiochip0: GPIOs 348-511, parent: platform/2200000.gpio, tegra234-gpio:
gpio-348 (PA.00 |fixed-regulators:reg) out lo
there is no pin 128
Which pin do you want to control? PAA.00 or PA.00?
It is PCC.02.
Jetson Orin Nano Developer Kit Carrier Board Specification
2.4 M.2 Key E Expansion Slot
Wi-Fi Disable
I just want to konw the status of pin (Wi-Fi Disable ),may be the Module Pin #128 Output 3.3V to disable WiFi module,but I don’t konw equivalent pin.
It is PCC.02.Can you offer related documents
In Jetson Orin Nano Developer Kit Carrier Board Specification:
PIN56 of J10(M.2 Key E Expansion Slot) is for Wi-Fi Disable.
Please also check the following part in pinmux spreadsheet to get the module pin#128 with PCC.02 .
is this document?cat /sys/kernel/debug/gpio
Why don’t directly show pin 128?why Linux use GPIOs 316-347 to replace original pin?why we should take long time to finger out which pin ?just display from pin1 as the document
Sorry that I can not open the link you shared.
PIN128 is from the perspective of the module itself.
They are enumerated by the Linux.
It is how GPIO pins work between schematic/pinmux/linux sysfs node. If you run sudo gpioinfo, then it will be another set of value.
Please note that it is a Linux system rather than the simple MCU architecture.
