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

まだ誰も着手していません。

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

まず、Raspberry Pi 5 のオンボード UART 設定で /dev/AMA0 を確認し、/dev/ttyUSB0 の動作している FTDI 設定と比較します。次に、報告されている Ubuntu 24.04 と micro-ROS Iron のセットアップを確認し、クライアントを変更せずに Agent がオンボード UART 経由で接続を確立できることを検証します。
