Sep 27, 2020Debugging the ESP32 in PlatformIO (using JTAG)When Serial.printf(); is not enough Sometimes you need to dig deeper if a peripheral or function on the ESP32 doesn’t work. The underlying FreeRTOS components and internals of the ESP32 can make it impossible to debug via a serial port. In that case, you can utilise the ESP32’s JTAG interface. This allows you to monitor…Programming2 min read
