Usb to swd. In this tutorial, we will use OpenOCD as the program on the host to send commands and communicate using SWD. After that updates could be easily flashed trough the same port with a standard USB-C cable. When I understood your explanation correctly then I have to use a usb connector with a usb-dfu compatible microprocessor for uploading new software + a swd interface for debugging which needs an adapter ST-Link or J-Link. We want to carry the SWDIO and CLK signals using the USB-C cable. Install ST-Link Software Thomson Semiconductor gives away free development software. We can use SWD to add a bootloader and then program through the USB port. We’ll use an FT2232H as the bridge to translate signals from the USB port to the SWD interface. The project is currently at the concept stage. 0 to UART/FIFO IC with a capability of being configured in a variety of industry standard serial/parallel interfaces: USB to SWD Schematic for FTDI FT232H -> SWD dongle. So you have a SWD debugger which is sending infos to your computer via USB, you want to read those USB messages in your application, right? Do you have an API provided with the SWD debugger? Which one is it? I like the idea to have a single USB-C connector which can be used for USB 2. Sep 17, 2023 · This guarantees a stable connection, allowing programming exclusively via the USB Type-C port, eliminating the need for full board access. JTAG/SWD Debugger Programmer with Micro USB Interface This is an additional option for other products, should not be ordered separately. Once I proved out that this all worked, I made the case to the hardware team and we switched to a USB-C connector and implemented SWD over USB-C. Aug 16, 2025 · The circuit has a USB-C port, but it's only used for 5V power; it doesn't use the USB protocol. I want to implement SWD (and potentially UART lines) over a type A to C USB cable to talk to the NRF52832 on our board. Learn how to make flashing your ARM-based MCU easy by using OpenOCD debugger with an FT2232H adapter.

Ezurio USB - SWD Programming Kit (453-00062-K1) is a Multi-function debugging & programming tool for a wide range of Ezurio modules & devices based on Nordic Semiconductor silicon. Mar 2, 2025 · Since we were about to do a new design iteration, I started investigating using SWD over USB-C at home. I want to make a custom USB-C to ST-link cable for debugging and flashing the USB DFU bootloader over SWD. In my case I want to use the USB-C connector for client software updates with Prieto's boards — programmed, amusingly, using another board that provides SPI rather than SWD over its USB connection — proved entirely successful, allowing Prieto and colleagues to debug their boards without having to find space in the design for additional dedicated connectors. The tutorial uses OpenOCD, an open-source debugging tool, with an FT2232H USB-to-serial bridge to communicate with MCUs via SWD. A USB to JTAG and SWD adapter for use with OpenOCD - HarmonInstruments/JTAG_SWD SWDPD-Debug-Probe-over-TypeC Board with online and offline firmware flashing via SWD, power control via PD and communication via USB. 54mm pitch) JTAG cable to a slimmer 2x5 (0. Tested with OpenOCD 0. Built dongle. 6") + 20 cm (8") JTAG cable SWD is an alternative to JTAG method for accessing the On-Chip Debug Access Port that allows low-level access to system resources such as system bus, memory, IO, even single stepping the code execution - a must-have for an Embedded Systems Developer and/or Analyst. SWD uses an ARM CPU standard bi-directional wire protocol, defined in How to implement SWD lines on Type A to C USB cable Ask Question Asked 7 years, 10 months ago Modified 7 years, 10 months ago Debugging and flashing via one mini-usb connector and that's what I want. 6V range Dimensions 50x40 mm (2x1. It's essentially an enhanced version of the ST-Link V2. FEATURES Plug-in adapter for ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-TINY, ARM-USB-TINY-H that allows ARM processors to be programmed/debugged via Serial Wire Debug (SWD) Tested and working with OpenOCD and Rowley Crossworks Compatible with targets that operate in 1. This adapter board is designed for adapting a 'classic' 2x10 (0. I'd like to be able to program my microcontroller (STM32G031G8) through the USB-C connector using a modified USB-C cable. Introduction The STM32 Nucleo-64 boards based on the MB1136 reference board (NUCLEO-F030R8, NUCLEO-F070RB, NUCLEO-F072RB, NUCLEO-F091RC, NUCLEO-F103RB, NUCLEO-F302R8, NUCLEO-F303RE, NUCLEO-F334R8, NUCLEO-F401RE, NUCLEO-F410RB, NUCLEO-F411RE, NUCLEO-F446RE, NUCLEO-L010RB, NUCLEO-L053R8, NUCLEO-L073RZ, NUCLEO-L152RE, NUCLEO-L452RE, NUCLEO-L476RG) provide an affordable and flexible way for users The Raspberry Pi Debug Probe is a USB-to-debug kit that provides the necessary hardware for solderless, plug-and-play debugging. 1"/2. Using this design, pin wires are replaced with a Type-C cable for the SWCLK and SWDIO lines. Can we improve the ST-Link programmer by introducing a USB Type-C interface for computer connections? Further, can it be adapted for projects that have a USB Type-C port? This project realizes these concepts. STM32 chips are more sophisticated than STM8 and SWD provide a powerful debugging interface. The star topology enables some parts of the system to be powered down, while others can still be accessed over JTAG; a daisy chain requires all JTAG interfaces to be powered. It also supports longer cables (1-2 meters) between the programmer and the target device. It's helpful for using products like the JTAGulator or SEGGER J-Link with tiny boards that use the 10-pin SWD programming connector.

With USB-C DAM (Debug Accessory Mode) this is possible. I've seen a few posts about this, but they are all old, and maybe don't apply to USB-C We have a device that already uses USB-C for battery charging. :) Jun 22, 2025 · Have you ever wanted to debug your microcontroller over USB-C? I’m talking full SWD (JTAG), not just USB-printfs! If you already have a USB-C connector, there’s no need to have additional connectors (or Tag-connect pads) which take up space! The Ezurio USB-SWD Programming kit is the ideal accompaniment for your product development process that utilises Ezurio’s range of Nordic Semiconductor based modules and products. SWD is a 2-pin alternative to the traditional 5-pin JTAG, saving MCU pins. Jul 25, 2020 · STM and NXP have different methods for this. Have you ever wanted to debug your microcontroller over USB-C? I’m talking full SWD (JTAG), not just USB-printfs! If you already have a USB-C connector, there’s no need to have additional connectors (or Tag-connect pads) which take up space! In this talk, I’ll cover how to do things the "USB standard way" with all the bells and whistles as well as the YOLO, no additional components, way JTAG/SWD Debugger Programmer with Micro USB Interface This is an additional option for other products, should not be ordered separately. cfg \ However, you're not going to escape needing an SWD programmer or similar on-board, as that smaller microcontroller, which effectively converts USB to a protocol the primary processor can understand, needs to be programmed itself to be able to do that kind of conversion on the fly, so you'll need an SWD programmer to begin with anyway. Other two-wire interfaces exist, such as Serial Wire Debug (SWD) and Spy-Bi-Wire (SBW). 27mm pitch) SWD Cable. Please purchase together with the NRF51822 Boards. Serial Wire Debug (SWD) is a 2-pin (SWDIO/SWCLK) electrical alternative JTAG interface that has the same JTAG protocol on top. 10 and Atmel ATSAM4E, ft232h-module-swd. NXP uses something called " openSDA," which converts USB to a combination of SPI and UART for the NXP chipset, while STM uses ST-LINK to convert to USB to their SWIM (single-wire interface module) protocol for their chips. Currently, we only want to sink power only with no USB data. I like the idea to have a single USB-C connector which can be used for USB 2. . We don't expect to be able to just plug this into a computer to flash. Technical specifications may change in the future. This guarantees a stable connection FTDI FT232h is a single chip USB 2. To communicate with our target chip, we need a program on the host and hardware as a bridge between the host and the chip. 05"/1. 0 and also gives access to SWD (single wire debugging) both on the same USB-C connector. cfg is from OpenOCD git: openocd -f ft232h-module-swd. We can look inside the registers inside the processor and change bits in memory from our PC. 65V to 3. jxjy, 6knnw, x7pq, 9vtt, x4jga, hzqfn, wwgl, atp2r, ed2e, 9irn,
