So i update the firmware for DAPLink

0253_SAM3U2C_MKIT_DK_DONGLE_NRF5X_0X5000.BIN to break this limit of license.

No, the nRF5x-DK is for Nordic devices only. It is not licensed to flash any other manufacturer. This CMSIS-DAP JTAG is the alternative not limited to Nordic. It comes with software to flash softdevice et al... can also be used with any MCU supported by the OpenOCD or the IDE you are using. Both SWD and JTag mode are supported.

hi, I have another question:

After switching to the firmware of supporting CMSIS-DAP. Can I use this nrf51-DK as CMSIS-DAP debugger or flash the external MCU(eg: STM32F103 etc.) by P20, just the like the following:

hi, hongtao:

After switching to the firmware of 0253_sam3u2c_mkit_dk_dongle_nrf5x_0x5000.bin, i can get DAP-LINK, not J-Link. but I cannot get MBED CMSIS-DAP, the mbed virtual com and mbed usb are fine. I have installed the CMSIS-DAP driver for windows XP several times. it cannot work still.

Another CMSIS-DAP debug probe.

IBDAP from armstart.com

Fully Open source CMSIS-DAP implementation in GNU gcc and make.

Here's another tutorial how to program nRF51822 using OpenOCD under Windows, Linux and Mac:

Yes, that how I entered in Mbed mode, but there is no info on CMSIS-DAP debugging. BTW, will nRFgo support CMSIS-DAP? programming?

Yes, I got some very useful info there, thanks.

After taking a half day work, I finally make it works. It is very exciting to know that CMSIS-DAP works so well.

First, you need download the CMSIS-DAP driver here:
After install the driver, you will find 3 devices in your PC, they are a MBED USB Drive, a MBED CMSIS-DAP, and a virtual COM:
Config the Keil debug tool to CMSIS-DAP:
Be sure to set your CMSIS-DAP to SWD mode, otherwise your CMSIS-DAP is inactive with gray color.
Copy the nrf51xxx.flm file from "C:\Keil\ARM\Pack\NordicSemiconductor\nRF_DeviceFamilyPack\1.1.4\Flash" to C:\Keil\ARM\Flash", And load the flash algorithm file by manual.

And then you go! the CMSIS-DAP works very similar to JLINK, it is also offers a virtual COM for UART debug. Except you can't use it with nRFgo.

Enjoy!

Hi,

If you check out the user guide for the nRF51-DK, there's a chapter there which describes how to switch out the firmware on the debugger IC.

It's basically to hold in button "IF BOOT/RESET", then plug in the USB cable. A drive called "BOOTLOADER" should appear, and you can drag the .bin file over to this drive.

The binary file for the CMSIS-DAP is located here: www.nordicsemi.com/.../21120532

If you want to switch back to JLINK, just download the .bin for that and repeat the process: www.nordicsemi.com/.../30216378

Cheers, Håkon

This blog post is more orientated toward gang programming, but there is information about debugging as well: Blog post
