+# In-circuit debugging using openocd and gdb
+
+## Hardware
+Connect an ST-Link V2 programmer to the SWD pins on the board. The pins that need to be connected are:
+- GND
+- VTref
+- SWDIO
+- SWCLK
+- NRST
+
+Make sure you're using a genuine one for boards that do not have a 3.3V panda power rail. For example, the tres runs at 1.8V, which is not supported by the clones.
+
+## Openocd
+Install openocd. For Ubuntu 24.04, the one in the package manager works fine: `sudo apt install openocd`.
+
+## GDB
+You need `gdb-multiarch`.
+
+Once openocd is running, you can connect from gdb as follows:
+```
+$ gdb-multiarch
+(gdb) target ext :3333
+```
+To reset and break, use `monitor reset halt`.
