CMSIS DAP/DAPLink Emulator Simulator STM32 Debugger Downloader Keil JTAG/SWD/Serial Port/U Disk Drag Drop Super JLINK/STLINK

1.Description:

It is a CMSIS DAP Simulator.CMSIS DAP emulator is an emulator with open source hardware and software,which is easy to use.

2.Feature:

1).The burning speed is fast,without losing the firmware.

2).No copyright risk,rich functions,can better meet the needs of electronic engineers for daily development,debugging and downloading.

3).The price is low,and the appearance is simple and exquisite.

4).Support JTAG/SWD interface.

5).Support virtual serial port.This emulator can be used as an emulator,but also as a serial tool,instead of ch340,cp2102,pl2303.

6).Support U-disk drag and drop burning.

3.Parameter:

1).Product Name:CMSIS DAP Simulator

2).Debug Interface:JTAG,SWD,virtual serial port

3).Development Environment:Keil/MDK,IAR,OpenOCD

4).Target Chip:All chips based on Cortex-M core,such as STM32,NRF51/52,etc.

5).Operating System:Windows,Linux,Mac

6).Input Voltage:5V (USB power supply)

7).Output Voltage:3.3V/5V

8).Work Temperature:-25℃~85℃

9).Work Humidity:5%~95%RH

10).Size:74*25*16mm

4.JTAG/SWD Interface:

1).JTAG interface:With OpenOCD,it can support debugging of almost all SoC chips worldwide,such as ARM Cortex-A series,DSP,FPGA,MIPS,etc.

2).SWD interface:Mainstream PC debugging software,including keil,IAR,and openocd,all support single-step debugging and downloading using the SWD interface.

5.Common Problem:

1).Question:When the programming fails,it prompts RDDI-DAP ERROR,what should I do?

Answer:Due to the faster programming speed of the emulator,crosstalk will occur between the signals between the Dupont cables.Please try to change to a shorter Dupont cable,or pull apart the closely connected Dupont cables.You can also try to reduce the programming speed.Generally it can be resolved normally.

2).Question:The target cannot be detected,and it prompts communication failure,what should I do?

Answer:Please first check whether the hardware wiring is correct (GND,CLK,I0,3V3),and then check whether the power supply of the target board is normal.If the target board is powered by the emulator,since the maximum output current of USB is only 500mA,please check whether it is possible to supply power to the target board.insufficient.

3).Question:What chips does CMSIS-DAP/DAPLink currently support for debugging and programming?

Answer:The typical use scenario is to program and debug the microcontroller.In theory,the cores of the Cortex-M series can be programmed and debugged using DAP.Typical chips are the full range of STM32 chips,the full series of GD32,and the nRF51/52 series.

4).Question:Can the DAP simulator be used for debugging under 1inux?

Answer:1 Inux,you can use openocd with DAP emulator for debugging.Openocd is currently the most popular and powerful open source debugger in the world.On the host computer,because openocd is cross-platform,you can also use openocd under windows.Writing appropriate configuration scripts can realize the debugging and burning of the chip.

6.Steps for Usage:

1).Connect the emulator to the target board.

2).Connect the emulator to the PC.After the emulator is connected to the PC normally,a virtual serial port and USB-HID device will appear in the device manager of the computer.

3).Configure the development environment.

4).Download the firmware to the target board.
