I just installed trial version of VisualGDB and followed the tutorial “Creating Advanced ESP32 Projects with ESP-IDF” at https://visualgdb.com/tutorials/esp32/esp-idf/. As I dont have any JTAG debugger device, I set “Builtin GDB simulator” for debugging. As I hit Start in VS2019, I get error < ^error,msg=”Don’t know how to run. Try \”help target\”.” >. Is there any guide about very basics of using VGDB, how to run without debugging, how to see “Embedded-friendly Memory View”, “Real-time Watch and Dynamic Analysis” etc. for some one very new like me?
For most of the targets (including ESP32), the built-in gdb simulator is not sufficient to run any meaningful code and can only be used to test that gdb can load the image and parse the symbols. Generally, we would advise getting one of the boards supported by VisualGDB (see our ESP32 tutorials).
