ESP-Prog¶
ESP-Prog is one of Espressif’s development and debugging tools, with functions including automatic firmware downloading, serial communication, and JTAG online debugging. ESP-Prog’s automatic firmware downloading and serial communication functions are supported on both the ESP8266 and ESP32 platforms, while the JTAG online debugging is supported only on the ESP32 platform. Vendor information…
Configuration¶
You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):
[env:myenv]
platform = ...
board = ...
debug_tool = esp-prog
If you would like to use this tool for firmware uploading, please change upload protocol:
[env:myenv]
platform = ...
board = ...
debug_tool = esp-prog
upload_protocol = esp-prog
More options:
Drivers¶
- Windows:
See https://community.platformio.org/t/esp32-pio-unified-debugger/4541/20
- Mac:
macOS contains default FTDIUSBSerialDriver driver which conflicts with debug tools which are based on this chip. FTDI Chip company recommends removing this default driver from a system. Everything should work after system rebooting. See detailed instruction in official application note (Page 16, Section 4: Uninstalling FTDI Drivers on OS X) AN134: FTDI Drivers Installation guide for MAC OS X
- Linux:
Please install “udev” rules 99-platformio-udev.rules. If you already installed them before, please check that your rules are up-to-date or repeat steps.
