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

还没有人认领这个 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

首先检查 Raspberry Pi 5 的板载 UART 配置中的 /dev/AMA0，并将其与 /dev/ttyUSB0 上正常工作的 FTDI 配置进行比较。查看报告中的 Ubuntu 24.04 和 micro-ROS Iron 设置，然后验证 Agent 是否能够通过板载 UART 建立连接，而无需更改客户端。
