2.1. LEDs description.
CoLinkEx programmer have four LEDs for status indication
PWR – show status of programmer power supply
Connect – status of connection to USB
BUSY – this LED is ON if programmer in debug mode
ERROR – this LED is ON if any error is occur
3. JTAG interface
CoLinkEx have a standard JTAG connector. The JTAG connector is a 20 way Insulation
Displacement Connector (IDC) keyed box header (2.54mm male) that mates with IDC
sockets mounted on a ribbon cable
The following table lists the CoLinkEx JTAG pinout.

7. How to supply target board from CoLinkEx
With CoLinkEx adapter, you can supply target board with 3.3V/400mA or 5V/400mA via JTAG connector.
7.1. Power supply with 3.3V
For using this function, you must close “3V3” jumper. In this case, 3.3V from on-board voltage
regulator will be connected to pin 1 of JTAG connector. On target board 3.3V power supply bus
must be connected to pin 1 of JTAG connector.
7.2. Power supply with 5V
For using this function, you must close “5V” jumper. In this case, 5V from USB will be connected
to pin 19 of JTAG connector. On target board, 5V power supply bus must be connected to pin 19
of JTAG connector.

8. Installation of CoLinkEx
8.1. Install the Driver of CoLinkEx
You can download driver from http://www.coocox.org/Colinkex.htm
Do the operations shown in the following picture

8.2. Connect CoLinkEx to PC
When you connect CoLinkEx to PC, it will ask you to install the driver to system for the new detected
devices. Then you may need to specify the path for CoLinkEx Driver. After you installed the driver, in the
device manager, you will found CooCox（COM x）under Port and CooCox CoLinkEx Debug Interface
under USB Controller. If there is a “?” in front of the two devices, it means that the driver have not been
installed to the system or install failed; if there isn’t CooCox Port, it means that your CoLinkEx firmware
and driver is old version.
9. Update the firmware
You can download firmware from http://www.coocox.org/Colinkex.htm
How to update the firmware:
9.1. Short-circuit JP1 (activation of USB bootloader)
9.2. Connect CoLinkEx to the PC. Wait for the PC enumerates the removable disk whose label is
"CRP2 ENABLD" or "CRP DISABLD". If it does not, you could press the reset button (BP1) for
several times or power on again.
9.3. Delete the firmware.bin file in removable disk
9.4. Copy the downloaded firmware: ColinkEx_firmware_v0.4.bin into the removable disk
9.5. Disconnect JP1, power on again, then CoLinkEx will work normally

10.2. How to use CoLinkEx in CoFlash
Open CoFlash, select a chip, e.g. (LPC11C14x301 from NXP), then select CoLinkEx in the adapter; modify
the Port, Max Clock for the adapter if you need. You can refer to the following picture
Switch to Download page to execute Download, Erase, Verify, Blank Check, etc

10.3. How to use CoLinkEx in MDK
Before using CoLinkEx in Keil MDK you must install «CoLinkEx plugin for MDK» from
http://www.coocox.org/Colinkex.htm
Open MDK Project, Click Target options to configure the project
“Debug -> Use”, open the configuration dialog and selects "CooCox Debugger".

16
Click "Settings", and then select the “CoLinkEx” as the adapter. You can also modify the Port, Max Clock
for the adapter, Reset, Cache, Trace or Semihosting Options, etc.
Switch to Flash Download to set the flash options and the flash algorithm.

Then, if you debug your program in flash, you also have to configure "Utilities" by selecting "CooCox
Debugger" for Flash Programming
Now you can use CoLinkEx to download and debug in MDK
