Open KTAG J-Link B8 ADD tokens file.

Check out how to solder KTAG’s PCB.

Solder the PCB; make sure circuit board of PCB is well welded like that in the picture.


Connect the PCB to a laptop’s USB port to charge. If the PCB board is not charging, its software will not work properly.


Next come to KTAG J-Link software installation.

Double click Setup JlinkARM to start the installation.

Click “Yes”.

Click “Next”.

Click “Next”.

Select Add shortcuts to desktop, click “Next”.

Click “Next”.

Click “Finish”.


The KTAG tokens are limited, but there is a way to add tokens for free:

Copy KTAG BIN File and paste it on the desktop.

Delete the extra JFLASH ARM V4.24c.

Connect the USB cable of KTAG tool to the computer. Since there is no KTAG software in this PC, the driver won’t be installed but that’s ok. We only need the USB cable to charge the PCB.

Open “Computer Management”.

Click “Universal Serial Bus Controller” and look for “J-link driver” in the submenu. This means the J-link driver is installed.



Select “Options”.

Click “CPU”, Select “Device” and then the CPU type that you are going to remap.

Select “Auto detection” and click “OK”.


Select “Options” and click “target interface”.

Select “Auto selection” and click “OK”.


Click “File” and choose “Open data file”.

Select “KTAG software” and click “Open”.

Click “OK”.

Select “Target”.

If you get an update message, you can decide whether to update the software or not. Here we will accept the upgrade.

Select “Target” again, and then Auto after the upgrade is finished.

JFlash programming will then start automatically and the KTAG tokens will be added when the programming is complete.
