Do you want to make a blinker?
Or a constant light?

If you want to make a blinker:

Setup (IOport);
REPEAT
SetBit (Led, 1);
Wait (200);
SetBit (Led, 0);
Wait (300)
UNTIL PigsCanFly;

It's up to you to fill in the procedures Setup, SetBit and PigsCanFly.

OK, I'm an old guy, but when I learned programming the Z80, I read the Z80 technical user manual, plus all datasheets for the support and the peripheral circuitry several times. Same for the 8086, PIC 16Cxx, AVR, Z8 and now the ARMs.

I guess you do the same. Look for sometjing like 'reset condition'. The datasheet holds it all. And if it doesn't, let me know, I know a few NXP engineers. :0)

After reading the datasheet you *KNOW* the chip. You *Know* what it can and what it might be able to do more. If the Arm is your first micro processor, go spend a few weeks in the datasheets. If you've done other processors before, just skim through the PDF files. In essence the ARM and the PIC are similar. The Arm is just a little bit more powerful. ;o)

Hi,I tried and looked it in crossworks simulator in debug mode.The instructions work as expected, but when I flash it in processor it does not do anything.

Here’s my set of conjectures:

1. You don’t have a JTAG adapter so you can’t debug the application on the hardware.

2. You loaded the program using Flash Magic.

3. You did not read the startup code.

4. You did not read the FAQs on our helpdesk.

5. You did not read the package documentation.

Fixing (1) will bring you the most benefit. If you don’t fix (1) there is little hope of fixing other problems quickly.

Hi Aamir

As I see, you are really beginner, let's say level 0 or less.

Some points

- as told earlier read the PDF, or some ARM documents. Currently there are several ARM core version existing.

- which type of ARM do you start with? Manufacturer, device ...? The startup code must match the device. You use CrossWorks probably the startup code is added by linker. But linker must know which device do you use. Startup code is there to get the ARM to execute the 'main'.

- By the way where the compiler/linker placed the code FLASH or RAM?
becasue simulator does not care where the code is. it will be executed. But in microcontroller the code must be in right place. Usually it is FLASH, but code compiled for RAM can't be placed in flash.

- Finally what you have loaded into microcontroler? You have presented only C program. CrossWorks must have generated some executable/binary/hex file.

- Last thing is your board, try to hard-wire the P0.5/P0.6 pins to get the power on always. I can't even imagine how the controller can run when it is not powered.

1 : I have already ordered CrossConnect USB JTAG last monday, hoefully will recieve it soon.

So you don’t have any eyes to debug this with.

2 : I loaded it using MikroElektronika USB ARMprog (does it make any difference??) The Instalation guys of my company use same and I have to make the working for this flash loader even if there is any difference??.

There probably is no difference.

3 : I have not read the start upcode, but what should I do with it even if I read????

You will be enlightened. Search for startup problems and how to fix it. And pre-processor defines. Or read the source code that is placed into the project under the System Files folder.

4 : OK I will read FIQs from your helpdesk (rowley support page r8???).

Not FIQs, FAQs.

5 : I have read the documentation, but I will do it again if you have this impression.

If you had read the documentation, you would know what was wrong and how to fix it. Start with the source code and read the FAQs.

Aamir, I was going to suggest that you take an existing IDE like LPCXpresso
et al. and check the demo projects for the CPU you are targeting. These are
proven pieces of code. Then, modify main() to fit your needs. ARM is not the
most straightforward architecture to get started, although it is a powerful
machine once you get used to it.

If you already have a working demo from a (past?) colleague, take the source
code and check the startup file (hint: exception vectors, thumb instruction
set, odd/even addresses, etc.). This may give you a first indication.

Getting started from scratch would take a significant amount of time and
frustration to get to a simple "while(1);" without the right tools.

 1 : I have already ordered CrossConnect USB JTAG last monday, hoefully will recieve it         soon.   So you don’t have any eyes to debug this with.  2 : I loaded it using MikroElektronika USB ARMprog (does it make any difference??) The Instalation guys of my company use same and I have to make the working for this flash loader even if there is any difference??.  There probably is no difference.  3 : I have not read the start upcode, but what should I do with it even if I read????  You will be enlightened.  Search for startup problems and how to fix it.  And pre-processor defines.  Or read the source code that is placed into the project under the System Files folder.  4 : OK I will read FIQs from your helpdesk (rowley support page r8???).  Not FIQs, FAQs.  5 : I have read the documentation, but I will do it again if you have this impression.  If you had read the documentation, you would know what was wrong and how to fix
it.  Start with the source code and read the FAQs.  -- Paul.   Start a New Thread
