Ontario-based EZ32 is making ready a crowdfunding marketing campaign for a compact instrument that mixes an Espressif ESP32-S3 with a small field-programmable gate array (FPGA) to ship wi-fi debugging and serial bus entry capabilities — whereas doubling as a helpful growth board: the ESP32JTAG.
“ESP32JTAG is the Swiss military knife-style instrument for embedded {hardware} engineers,” claims EZ32’s Andrew Li of the corporate’s upcoming system. “It combines a number of important debugging and growth instruments right into a single system. With assist for MCU [Microcontroller Unit] on-chip debugging (OCD), FPGA growth, logic evaluation, UART terminal entry, and extra — all working concurrently — it successfully replaces a number of USB dongles whereas providing higher efficiency.”

The tiny gadget is constructed round an Espressif ESP32-S3-WROOM-1 module, giving it two Tensilica Xtensa LX7 cores operating at 266MHz, 8MB of pseuo-static RAM (PSRAM), and 16MB of flash storage. Linked to that is an FPGA with 5k gates and 1Mb of RAM, which powers each the versatile debugging capabilities — JTAG and Serial Wire Debug (SWD), UART with WebUART assist, a 16-channel logic analyzer, goal voltage monitoring, and reset management — and permits the system to double as a both a microcontroller or FPGA growth board.
The Espressif module additionally offers Wi-Fi and Bluetooth connectivity, permitting for wi-fi debugging — whereas an on-board 1.83″ LCD panel offers standing stories and the gadget’s IP deal with, permitting the built-in internet interface, operating atop the FreeRTOS real-time working system, to be simply discovered. Stated interface permits for on-the-fly system configuration, over-the-air firmware updates, and standing monitoring, with quick access to documentation.

The present iteration of the ESP32JTAG runs openocd-on-esp32, blackmagic-debug, openFPGALoader, and CMSIS-DAP (DAPLink), Li has confirmed. He has additionally pledged to launch schematics, a invoice of supplies, “and extra” beneath an unspecified open {hardware} licence within the close to future.
Extra data is obtainable on the ESP32JTAG Crowd Provide web page, the place events can signal as much as be notified when the crowdfunding marketing campaign goes dwell.
