ARMflash PROGRAMMER

Along with complementary software, ARMflash programmer represents an irreplaceable tool for allthose working with ARM microcontrollers. By means of this programmer, it is possible to program

almost all ARM microcontrollers including those embedded (soldered) on the printed board. The

ARMflash programmer is connected to the microcontroller via four lines:

P0.0 - TX (transmitter output);

P0.1 - RX (receiver input);

P0.14 - ENT (enter programming mode); and

RESET (external reset).

These lines are contained within a flat cable ending with a female IDC-10 connector. When creat-ing a target device, the appropriate 10-pin IDC male connector with the spacing of 2.54 mm

between pins should be soldered on it. Connector pins should be connected to the microcontroller

pins the position of which varies depending on the microcontroller’s type and package. There are

several examples of connection schematics provided at the end of this manual. During operation,

the ARMflash programmer may be inactive or active.

Programmer is inactive

A multiplexer within the pro-

grammer connects the micro-

controller pins to peripheral

components on the printed

board via flat cable. In thisway, the microcontroller

directly controls the operation

of device without affecting the

operation of the programmer.

Accordingly, even the IDC-10

female connector is connect-

ed, the ARMflash program-mer does not affect the oper-

ation of device.

Programmer is active

By clicking the WRITE option,

the multiplexer within pro-

grammer disconnects the

microcontroller pins from the

rest of on-board electronics. It

allows programming of the

microcontroller using TX, RX,

ENT and RESET signals.

When programming process

is completed, the ARMflashautomatically changes its

state and becomes inactive.

If the target board has its own 5V power supply, it can also be used for powering the ARMflash program-mer. In this case, it is necessary to open ARMflash programmer plastic case and remove the jumper forpower supply selection. Otherwise, if the target board does not have its own power supply source, the

jumper should be left on. In this case the programmer is powered via programmer USB cable which con-

nects the programmer to a PC. Any other power supply on the target board must be suspended.

This figure illustrates the position of jumper when the program-

mer is powered via USB cable.

This figure illustrates the programmer without jumper for power sup-

ply selection. In this case the programmer is powered by the target

board which has its own power supply.

start the installation from your hard drive. A welcome

window will appear on your screen. Click Next to pro-ceed with the installation process.

Step 2: License Agreement

Prior to starting the installation, please review the License

terms. To accept these, select the option I accept theterms in the License Agreement and click Next.

Step 3: Choose Components

For the sake of simplicity, this step of installation offers

you only one component to select. Just click Next.

Note: Make sure that the ARMflash programmer is not connected to PC during the ARMflash software installation.

Step 4: Choose Install Location

Now you should specify the folder to install the program in.

If you want to install the program in a folder different from

default, click Browse and select another folder on harddisc. Then click Next. If you choose the default folder, theprogram will be installed on the following destination:

C:\Program Files\Mikroelektronika\ARMFLASH

Step 5: Installation Details

The ARMflash installation will start in this step and itsprogress will be shown on the screen. If you are inter-

ested in details about the installation click the Showdetails button.

Step 6: Finish

You will be notified by the window, as shown in Figure on

the right, that Windows has successfully installed the

ARMflash. Click Finish to complete the installation process.

ARMflash SOFTWARE

Step 1: Run the ARMflashprogrammer

Run the ARMflash from your PC. Click the Device optionand select the appropriate microcontroller to program.

ARMflash will automatically set parameters for workingwith the specified microcontroller.

Step 2: Load HEX file

Click the Load option which opens the window shown inFigure on the right. Select the appropriate executable file

(has extension .HEX in its name) and click the Openoption. In this way, the file will be loaded into programmer

buffer. On the basis of control bits stored in the HEX file,

the ARMflash will do all necessary settings.

Step 3: Write a program

Click the Write option in the upper right corner of theworking window to start programming the microcon-

troller. The programming progress will be shown in the

right bottom corner of the working window.

Alternatively, you can use the ARMflash programmer from the command line.This way, you will be enabled to use the ARMflash programmer from someother software, compiler etc. Here is the list of command line parameters:

-w Write to ARM

-v Verify

-e Erase ARM

-r Read from ARM

-p ARM name (for example: LPC2148, LPC2214...)

-f File name (must be enclosed with " “)

-b Blank check

-q Close ARMflash after programming

armflash.exe -w -pARMLPC2148 -v -f"C:\somefile.hex"

This will program the ARM microcontroller using C:\somefile.hex. Imme-

diately after write, it will verify loaded file.

armflash.exe -r -pARMLPC2148

This will read the ARM program memory.

armflash.exe -e -pARMLPC2148

This will erase program from the ARM microcontroller.

PROGRAMMER’S OPERATION

Programming an ARM microcontroller is performed using signals TX, RX, ENT and RESET from the

ARMflash programmer. These are brought to the P0.0, P0.1, P0.14 and RESET pins. Additionally,the microcontroller pins VCC and GND must be supplied with 3.3V power supply voltage. In order

to enable programming to run without errors, make sure that the programming pins are not connect-

ed to other electronic components during programming. Otherwise, during normal operation, these

pins must be connected to other components as per project.

Since the microcontroller is soldered on

the printed board (with no use of sock-

et), it is necessary to enable switching

over between the programmer and

other components using jumpers. For

this reason, it is important not to forget

to solder an IDC-10 male connector

during device design.

ARMflash PROGRAMMER CONNECTION

During programming, an IDC-10 female connector should be plugged in the on-board IDC-10 male

connector. This connection enables the programming signals to be transferred from the programmer

to the microcontroller. Pay attention to the orientation of the female IDC-10 connector. It has to be

properly oriented in order to make this programming work. Refer to the Figure below.

The ARM microcontroller power supply voltage is +3.3V. As it is

not provided by the programmer, it is necessary to provide an on-

board regulator marked as REG in the Figure above. If your

ARMflash programmer is not supplied over USB cable, it is nec-essary to provide additional +5V power supply for its operation.

Figure on the right illustrates an IDC-10 connector’s pinout. Pins

on the left side of the connector are used for connection to the

microcontroller, whereas the pins on the right side are used for

connection to other components.

Connection schematic for the on-board IDC-10 male connector and 44-pin ARM microcontroller

such as LPC2103. These microcontrollers need additional 1.8V power supply which must be provid-

ed on-board.

The following examples illustrates the connection between 44, 48, 64 and 144-pin ARM microcon-

troller and IDC-10 male connector.

During normal operation, its pins must be connected using jumpers as shown in Figure below. In this way,

the microcontroller pins are connected to the rest of on-board electronics. Note that only three middle pairs

of pins (P0.0, P0.1 and P0.14) of the IDC-10 male connector are connected using jumpers. You must not

connect end pairs of pins as connecting power supply pins (VCC +3.3V and VCC +5V) can damage the

device, whereas connecting the RESET and GND pins can cause the device to malfunction.
