Introduction

CoLinkEx is a hardware-debugging adapter, which supports SW debugging and supports ARM Cortex M

devices, it supports debugging in CooCox software and Keil RealView MDK. Main features of LPC1343-HB

module. In addition, ColinkEx can supply target board with 3.3V or 5V via JTAG connector

1. Features of CoLinkEX adapter:

Support JTAG and SW interfaces for Cortex-M microcontrollers

Supported in Coocox IDE (COIDE) and Keil RealView MDK (with plugin)

USB-B connector

Support firmware upgrade via USB

Standard 20-pin JTAG connector

Can supply target board with 3.3V or 5V via JTAG connector

4 LEDs for status of programmer

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.

Signal

TYPE

Description

3V3 OUT

Power

3V3 output for supply target board from voltage

regulator of CoLinkEx. Voltage on this pin available,

if “3V3”jumper is closed

2,3,11,17

This pin is not connected in CoLinkEx

TDI

output

JTAG data input of target CPU. It is

recommended that this pin is pulled to a

defined state on the target board. Typically

connected to TDI of the target CPU.

TMS

output

JTAG mode set input of target CPU. This pin

should be pulled up on the target. Typically

connected to TMS of the target CPU

TCK

output

JTAG clock signal to target CPU. It is

recommended that this pin is pulled to a

defined state of the target board. Typically

connected to TCK of the target CPU

TDO

Input

JTAG data output from target CPU. Typically

connected to TDO of the target CPU.

RESET

output

Target CPU reset signal. Typically connected

to the RESET pin of the target CPU, which is

typically called "nRST", "nRESET" or "RESET".

5V OUT

Power

This pin can be used to supply power to the

target hardware. Voltage on this pin available, if

“3V3”jumper is closed

4,6,8,10,12,14,16

GND

Ground

These pins connected to GND in CoLinkEx.

They should also be connected to GND in the

target system

TYPE

Description

3V3 OUT

Power

3V3 output for supply target board from voltage

regulator of CoLinkEx. Voltage on this pin available,

if “3V3”jumper is closed

SWDIO

Input/Output

Single bi-directional data pin. A pull-up

resistor is required. ARM recommends 100

kOhms

SWCLK

Output

Clock signal to target CPU.

It is recommended that this pin is pulled to a

defined state on the target board. Typically

connected to TCK of target CPU.

SWO

Output

Serial Wire Output trace port. (Optional, not

required for SWD communication.)

4,6,8,10,12,1

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

CoLinkEx JTAG/SWD adapter www.bravekit.com

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
