UM232H¶
The UM232H is a USB-to-serial/FIFO development module in the FTDI product range which utilizes the FT232H USB Hi-Speed (480Mb/s) single-port bridge chip to handle the USB signaling and protocols. Official reference can be found here
Configuration¶
You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):
[env:myenv]
platform = ...
board = ...
debug_tool = um232h
If you would like to use this tool for firmware uploading, please change upload protocol:
[env:myenv]
platform = ...
board = ...
debug_tool = um232h
upload_protocol = um232h

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. |
Wiring Connections¶
Please read 4. UM232H Pin Out and Signal Descriptions section for details.
| UM232H Pin | Board JTAG Pin | Description |
|---|---|---|
| GND | GND | Digital ground |
| AD0 | TCK | JTAG Return Test Clock |
| AD1 | TDI | Test Data In |
| AD2 | TDO | Test Data Out |
| AD3 | TMS | Test Mode State |
| RST# | RESET | Connect this pin to the (active low) reset input of the target CPU (EN for ESP32) |
You will also need to connect VIO to V3V and USB to 5V0 of UM232H to power the FTDI chip and board. See UM232H Datasheet
