TMS. The four JTAG connections from the FT2232H to our ESP32-WROVER module are a carbon copy of what is shown in ESP32-WROVER-KIT_SCH3, with the exception of the exception of the S_TDI arrangement shown in the JTAG section of that schematic. ESP-Prog is one of Espressif’s development and debugging tools, with functions including automatic firmware downloading, serial communication, and JTAG online debugging. This is thanks to FT2232H chip that has two USB channels, as loading of application directly with JTAG is not yet implemented. FT2232H also features USB-to-JTAG interface which is available on channel A of the chip, while USB-to-serial is on channel B. The FT2232HL is dual high-speed USB to UART/FIFO device, and similar FTDI devices are used on many boards as UART to USB converters. I'm about to buy a JTAG debugger. In JTAG Debugging the ESP32 with FT2232 and OpenOCD I have used a FTDI FT2232 breakout board to JTAG debug with OpenOCD. 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. the line with “before” is the original PID and VID. - FTDI 2232HL module with USB connector starting at 8$ on ebay and no paid software is required.
