However only one of these channels is used as a serial port, while the other is used as JTAG. When the OS loads FTDI serial port driver, it does so for both channels of FT2232 chip. On macOS, using FT2232 for JTAG and serial port at the same time needs some additional steps. 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.
