Dec 5, 2018 · FYI, many pins are GPIO, and the specific function depends on device tree. Some other pins may be dedicated as a UART (special function I/O, SFIO) and not designed to be GPIO. Even cases where a pin is dedicated to a non-GPIO function there may be device tree settings related to the controller of that pin, e.g., power rails.

Jan 14, 2025 · You can refer to Jetson/L4T/peripheral/ - eLinux.org for the UART mapping on Xavier NX. There’re 3 UART interface available on Xavier NX, but one is used for debug purpose by default. I would suggest you using USB serial console cable or UART expansion modules like SC16IC7x2/MAX14830 from I2C/SPI interface for more UART interfaces.

Oct 1, 2024 · Hi dear developers, I am using Jetson Xavier NX Developer Kit with the following Jetpack version: nvidia-l4t-core 32.6.1-20210726122859 # R32 (release), REVISION: 6.1, GCID: 27863751, BOARD: t186ref, EABI: aarch64, DATE: Mon Jul 26 19:36:31 UTC 2021 I am facing a problem using the UART from pins 8 and 10 (BOARD mode). My setup is very simple: I am trying a loopback for self test. I used a ...

Feb 12, 2021 · Hello! I’m trying to use gpio uart pins on jetson AGX devkit (JetPack 4.4.1). All operations i made in python3 with pyserial. I tried 2 schemas: I connected pins with rs232 (6(GND) - gnd, 8(TX) - RX, 10(RX) - TX), then connected rs232 to usb serial adapter(rs232-usb) and connect in to usb on same jetson. So i got 2 ports: /dev/ttyUSB0 and /dev/ttyTHS0. I can send data from usb0 to ths0 and ...

Mar 1, 2021 · Hello, I’m trying to connect my Pixhawk to the Xavier NX using the UART Ports on J14. I have verified that the connection works using an UART to USB adapter, but to keep all USB ports open for other hardware, I want to connect it directly to the UART Port. I also have a Jetson TX2 where I can “cat” on “/dev/ttyTHS1” and see the output. On the Xavier it doesn’t show anything. Does ...

Jul 14, 2021 · I dont understand what is the problem. Here is a tutorial about using UART on Jetson Nano. It might be helpful to follow the steps like tutorial. JetsonHacks – 11 Oct 19 Jetson Nano - UART - JetsonHacks. The UART on the NVIDIA Jetson Nano Developer Kit GPIO Header is simple to use, but there is a trick you should know before starting.

May 9, 2017 · You would use an ordinary serial console program such as minicom (or my favorite gtkterm) from a host PC (most serial console programs have a logging option).

Aug 2, 2019 · How to transmit and receive data through the uart pins. I want to connect the FPGA through UART pins and make communication in between. TomNVIDIA August 2, 2019, 4:11pm

Apr 6, 2021 · I’m currently plugging in my uart to pins 1ground, 4rx, and 5tx. I’m trying to write to a serial port using “/dev/ttyTHS2” as the port. I’m writing to the port but the arduino connected can’t read anything. Am I doing an…

Nov 20, 2017 · Note that GPIO pins can be configured to do more than one function (but only one function at a time). You may see references to the device tree…this is how a GPIO pin can be set to different functionality when that pin is capable of doing more than one function.
