Olimex ARM-USB-OCD¶
3-IN-1 fast USB ARM/ESP32 JTAG, USB-to-RS232 virtual port and power supply 5-9-12VDC device (supported by OpenOCD ARM debugger software). Vendor information…
Configuration¶
You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):
[env:myenv]
platform = ...
board = ...
debug_tool = olimex-arm-usb-ocd
If you would like to use this tool for firmware uploading, please change upload protocol:
[env:myenv]
platform = ...
board = ...
debug_tool = olimex-arm-usb-ocd
upload_protocol = olimex-arm-usb-ocd
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.
