micro-ROS Agent on Raspberry 5 with /dev/AMA0 does not work

還沒有人認領這個 Issue。

Hello,

I have setup a micro ROS Agent on a Raspberry PI 5 and connected to microROS client with UART. The UART on the PI is connected to Pin14/Pin15 (Rx/Tx) with /dev/AMA0. Which does not work. I get no connection to client.

If I connect a FTDI USB-UART serial adapter the USB port and connect the agent to port /dev/ttyUSB0 it does work as expected.

The UART AMA0 connection to my PC does work, which I have tested with the minicom terminal and hTerm

This is my setup
- Hardware description: Raspberry Pi 5
- RTOS: Ubuntu 24.04
- Installation type: micro-ROS Agent
- Version or commit hash: micro-ROS iron

Does anyone have an idea why it does not work with the onboard UART. Are there any special settings I need to make?

many thanks in advanced

首先檢查 Raspberry Pi 5 的板載 UART 設定中的 /dev/AMA0，並將其與 /dev/ttyUSB0 上正常運作的 FTDI 設定進行比較。查看報告中的 Ubuntu 24.04 和 micro-ROS Iron 設定，然後驗證 Agent 是否能夠透過板載 UART 建立連線，而無需變更用戶端。
