The system console allows low-level access to the system, debug output and analysis of the system boot process. The most convenient way to connect it is by using a Dronecode probe, but a plain FTDI cable can be used as well.
:::tip The console should be used for debugging if the system won't boot. The MAVLink Shell may otherwise be more suitable, as it is much easier to set up and can be used for many of the same tasks. :::
The console is made available through a (board-specific) UART that can be connected to a computer USB port using a 3.3V FTDI cable. This allows the console to be accessed using a terminal application.
Pixhawk controller manufacturers are expected to expose the console UART and SWD (JTAG) debug interfaces through a dedicated debug port that complies with the Pixhawk Connector Standard. Unfortunately some boards predate this standard or a non-compliant.
:::note Developers targeting a number of different boards may wish to use a debug adapter to simplify connecting multiple boards. For example, the Dronecode probe comes with connectors for the Pixhawk Debug Port and several other boards. :::
Connect the 6-pos JST SH 1:1 cable to the Dronecode probe or connect the individual pins of the cable to a FTDI cable like this:
The system console can be accessed through the Dronecode probe or an FTDI cable. Both options are explained in the section below.

3DR Pixhawk v1 Flight Controller (also applies to mRo Pixhawk, Holybro pix32)
连接控制台连接后，请使用您选择的默认串口工具或下面描述的默认工具：
在 Ubuntu 上安装 screen （mac os 已经安装了它）：
| Pixracer / Pixhawk v3 | - | FTDI | - |
|---|---|---|---|
| 2 | + 5v (红色) | N/C | |
| 2 | UART7 Tx | 5 | FTDI RX （黄色） |
| 3 | UART7 Rx | 4 | FTDI TX （橙色） |
| 4（黑） | SWDIO | N/C | |
| 6 | SWCLK | N/C | |
| 6 | GND | 1 | FTDI GND (黑色) |
After the console connection is wired up, use the default serial port tool of your choice or the defaults described below:
下载 PuTTY 并启动它。
sudo apt-get install screen- 串口：pixhawk v1/pixracer 使用 57600 波特率
- 串口：骁龙飞控使用115200波特率
Connect screen at BAUDRATE baud, 8 data bits, 1 stop bit to the right serial port (use ls /dev/tty* and watch what changes when unplugging / replugging the USB device). Common names are /dev/ttyUSB0 and /dev/ttyACM0 for Linux and /dev/tty.usbserial-ABCBD for Mac OS.
screen /dev/ttyXXX BAUDRATE 8N1Download PuTTY and start it.
Then select 'serial connection' and set the port parameters to:
- 57600 波特率
- 8 数据位
- 1 个停止位
