The FT2232 can program a JTAG device or flash ROM in seconds, … > > Any ideas on how I can make this work? The FT2232 board has two USB-2-Serial ports. openocd -c "source [find load-jt_usb5.cfg]" -c "program STM3210C-EVAL_FW_V1.1.0.hex" Setup for TMS570LS3137. PRO_CPU: PC=0x40000400 (active) APP_CPU: PC=0x40000400 The OpenOCD setup for TMS570LS3137 board. BUT, as with any other open-source tool, you … Asynchronous serial UART interface option with full hardware handshaking and modem interface signals. esp32 interrupt mask on Info : Target halted. Asynchronous UART; JTAG; I2C; SPI; Parallel FIFO; The board includes two linear regulators offering either 3.3V or 2.5V IO. Note that the JTAGkey2 (FTDI based) setup includes a special command to process TDO on the falling edge. `1______VRef____3.3V` ** Verify Started ** BUT, as with any other open-source tool, you … — To make sure, type the ct2232. In JTAG Debugging the ESP32 with FT2232 and OpenOCD I have used a FTDI FT2232 breakout board to JTAG debug with OpenOCD. Info : Target halted. Erich. Compared to what I get with native J-Link this is really slow (but I won’t complain as OpenOCD is more of a hobby/free solution anyway). For this, connect pin 0 and 1 of the CDBUS plus GND: With this, I have both a debug connection plus a serial connection available. For a more convenient connection between the FTDI board and the ESP32 JTAG signals, I’m considering building an adapter board on top of the FTDI eval board with a mini 10-pin JTAG connector. I spent some more time experimenting with my two JTAG interfaces (one of them also FTDI based) connected to my ESP-32 WROVER. Thanks for the information about the resistors, I’m going to add them to my next design/iteration. With 200 kHz I get a download speed of 30.282 KiB/s, with 1000 kHz it was 30.345 kiB/s. PRO_CPU: PC=0x40000400 (active) APP_CPU: PC=0x40000400 **OPENOCD Configuration File Changes:** 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. No special setup needed for this. Licensed under GNU GPL v2 ** Verify Started ** The FT2232H is a USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC. JTAG is the original transport supported by OpenOCD, and most of the OpenOCD commands support it. PRO_CPU: PC=0x4009171A (active) APP_CPU: PC=0x40000400 I bought my FT2232H MiniMod for $20.00 USD. Or JTAG debugging might not operate at all afterwards. Warn : Flash driver of drom does not support free_driver_priv() Info : Using flash size 16384 KB PRO_CPU: PC=0x4009171A (active) APP_CPU: PC=0x40000400 `ftdi_tdo_sample_edge falling` Info : clock speed 14000 kHz It is ideal for development purposes to quickly prove functionality of adding USB to a … ** Programming Started ** Switch to choose between SPI/JTAG and I²C/SWD modes Indicator lights to aid debugging There’s no real need for Tigard-specific tools, and the board will work with standard tools and libraries including USB serial drivers, OpenOCD and UrJTAG for JTAG, Flashrom, PyFtdi/PySpiFlash, LibMPSSE, and other tools for the SPI interface, as well as LibMPSSE and PyFtdi/PyI2CFlash for the I2C interfaces. Out of stock. I’m using the NXP MCUXpresso IDE because this project is with the NXP K22FX512 microcontroller (the ESP32 is a slave of the K22 device). Selecting OpenOCD as your debugging tool with an adapter like FT2232H is a very good choice when you don’t have much budget to work with. Future Technology Devices International FT2232H Datasheet: Building your own bootloader gateway to ESP. Info : esp32: Debug controller 1 was reset (pwrstat=0x5F, after clear 0x0F). Hi Yvan, See the original article here. In “Eclipse JTAG Debugging the ESP32 with a SEGGER J-Link” I used a SEGGER J-Link to debug an ESP32 device with JTAG. Its drop-in compatibility with different tools eliminates the need for Tigard-specific tools to interface with any targets. shutdown command invoked Change ), You are commenting using your Twitter account. The FT2232HL is available around $10 from different web stores or from AliExpress: I’m using an Adafruit adapter board (Adafruit #2094) to make the connection between the FTDI and the JTAG pins.
