JLink Debug Probe
The J-Link debug probe is a closed-source, commercial hardware probe which supports almost all ARM Cortex-M devices. You need to install the J-Link drivers for this probe to work:
sh
# Ubuntu
wget --post-data "accept_license_agreement=accepted" https://www.segger.com/downloads/jlink/JLink_Linux_x86_64.deb
sudo dpkg -i JLink_Linux_x86_64.deb
# macOS
brew install segger-jlink설치가 완료되면, 다음을 사용하여 서버를 시작합니다.
sh
JLinkGDBServer -if swd -device STM32F765II그런 다음, 권장되는 JLink를 업데이트하고, 통신 중인 장치를 지정하라는 메시지가 표시될 수 있습니다. 특정 장치에 대한 자동조종장치의 문서를 확인하십시오.
Once that's done, the GDB server should be start listening on port 2331, e.g. like so:
sh
Checking target voltage...
Target voltage: 3.28 V
Listening on TCP/IP port 2331
Connecting to target...
Connected to target
Waiting for GDB connection...이제 자동조종장치(별도의 터미널에서)에서 현재 플래시된 정확한 elf 파일로 GDB를 시작할 수 있습니다.
sh
arm-none-eabi-gdb build/px4_fmu-v5_default/px4_fmu-v5_default.elf -ex "target extended-remote :2331"이제 연결되어야 합니다.
To use an IDE instead, see the instructions for Eclipse or VSCode. See the Embedded Debug Tools for more advanced debug options.
Segger JLink EDU Mini Debug Probe
The Segger JLink EDU Mini is an inexpensive and popular SWD debug probe. The probe's connector pinout looks like the image below (connect to this using an ARM 10-pin mini connector like FTSH-105-01-F-DV-K).
The pin mapping to connect the J-Link Edu Mini to Pixhawk Debug Mini is shown below.
| 핀 | 신호 | JLink |
|---|---|---|
| 1 | VREF | 1 |
| 2 | 콘솔 TX | |
| 3 | 콘솔 RX | |
| 4 | SWDIO | 2 |
| 5 | SWDCLK | 4 |
| 6 | GND | 3, 5 |
Note that none of the JLink debug probes have a built in serial connection, so you need to connect the console separately.
