To carry on with debugging environment setup, proceed to section Run OpenOCD. Now ESP-WROVER-KIT’s JTAG interface should be available to the OpenOCD. The other interface is routed to ESP32’s serial port (UART) used for upload of application to ESP32’s flash. The /dev/ttyUSBn interface with lower number is used for JTAG communication. If you see similar result and you are a member of plugdev group, then the set up is complete. To do so, select “Dual RS232-HS (Interface 0) and reinstall attached driver to the “WinUSB (v6xxxxx)”, see picture ls -l /dev/ttyUSB*Ĭrw-rw-r- 1 root plugdev 188, 0 Jul 10 19:07 /dev/ttyUSB0Ĭrw-rw-r- 1 root plugdev 188, 1 Jul 10 19:07 /dev/ttyUSB1

Original “FTDIBUS (vxxxx)” driver of this device should be replaced with “WinUSB (v6xxxxx)”. The first device (Dual RS232-HS (Interface 0)) is connected to the JTAG port of the ESP32. The driver name would be “FTDIBUS (vxxxx)” and USB ID: 0403 6010.Ĭonfiguration of JTAG USB driver in Zadig tool 

In Zadig tool go to “Options” and check “List All Devices”.Ĭheck the list of devices that should contain two ESP-WROVER-KIT specific USB entries: “Dual RS232-HS (Interface 0)” and “Dual RS232-HS (Interface 1)”. If they do not install automatically, then download them from and install manually.ĭownload Zadig tool (Zadig_X.X.exe) from and run it. Wait until USB ports of ESP-WROVER-KIT are recognized by Windows and drives are installed.

Using standard USB A / micro USB B cable connect ESP-WROVER-KIT to the computer. The following instructions can also be used for other FT2232 based JTAG adapters.
