i am using winarm i have run the example codes its fine.
i have written an ledblinking code

#include<stdio.h>

#define GPIO_BASE_ADDR    0xE0028000

#define IOSET0         (*(volatile unsigned long *)(GPIO_BASE_ADDR +
0x04))

#define IODIR0         (*(volatile unsigned long *)(GPIO_BASE_ADDR +
0x08))

#define IOCLR0         (*(volatile unsigned long *)(GPIO_BASE_ADDR +
0x0C))

void delay()

{

  int i;

  for(i=0;i<10000;i++){}

}

main()

{

  IODIR0=0x00ff0000;

  while(1)

  {

    IOSET0=0x00ff0000;

    delay();

    IOCLR0=0x00ff0000;

  }

}



i want to run this program on my arm lpc2148???
when i use make all error comes--> no rule to make target error no:2
plz do help???
there is any tutorial from beginning i have read some but everything
explain with the example code given

That is a make file error not a compiler error. Unfortunately you have
removes all the useful information from the message. Post the whole log.

You have fallen in to teh number one most common trap in embedded
systems. The device has hardware timers, it is better to use one of them
for delays, however if you insist on dooing a loop delay, do it
correctly:

 void delay()
{

  volatile int i;

  for(i=0;i<10000;i++){}

}

See:
http://www.embedded.com/columns/beginerscorner/990...
for the reason why your code will break.

no rule to make target
error no:2



this is the error what i get
what should i do.


          OR


Atleast somesay how to compile the above code and get .hex file????

You don't even try the suggestions that have been given here or those I
wrote in the reply to your e-mail. Insteat you write the same question
over and over again into forums and e-mails. Try to give more
information. At least the complete output of make.

That is really no more information that you posted in the first place. I
expected everything emitted to the console from the point you start the
make file to the end. There must be other information?

If not then your make file is invalid, and perhaps you should post that.

That is a different question, you have to get your make file right
first. It has to build the code before it can generate a hex file from
it.

Have you looked that the "ARM-GCC development resources" thread?
http://embdev.net/topic/129986. In particular the "Building bare-metal
ARM with GNU" link.
