Jetson Nano how to use UART on /ttyTHS1

When I use systemctl stop nvgetty systemctl disable nvgetty to restart the device, I still cannot receive data.

Even if I use echo “Hello, ttyTHS1” > /dev/ttyTHS1, I cannot receive data. What is the problem? Other settings are normal.

There is no problem when I use /dev/ttyTHS1 to send data, but I cannot receive data.

Hi 19980108,

Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?

Have you enabled HW flow control for ttyTHS1? (i.e. do you connect RTS/CTS)

Please share the dmesg and full device tree for further check.

[    1.152401] 70006040.serial: ttyTHS1 at MMIO 0x70006040 (irq = 64, base_baud = 0) is a TEGRA_UART

Can you short TX/RX and verify the loopback test with the following command?

$ sudo su
# stty -F /dev/ttyTHS1 115200 raw -echo
# cat /dev/ttyTHS1 &
# echo "test" > /dev/ttyTHS1

Have you enabled HW flow control for ttyTHS1? (i.e. do you connect RTS/CTS)

no

Unable to obtain test content

Are you using the devkit or custom board for Jetson Nano?

devkit

Could you share the full steps how you verify it locally?
(including the screenshot or block diagram of your connection setup)

I’m currently unsure whether it’s a hardware issue or a system issue. If neither of these is the problem, can I establish communication with a Pico W?
I’m connected to the GPIO4 & 5 on the Pico W. It can receive data, but the Jetson Nano isn’t receiving the data being sent.
That’s the situation at the moment.

It seem a MCU from Raspberry Pi. We don’t have this module to verify it locally.

We would suggest verifying loopback test before connecting to external UART device.
Please share the detailed steps how you setup/connect to reproduce the loopback test does not work issue.
