Beginner - Need help to evaluate Crossworks

Dear Forum

I purchased an Open1768 an NXP WaveShare LPC1768 to develop a product with Crossworks.

http://www.waveshare.com/wiki/Open1768

Flash Magic is Version 7.45.3128

The platform is supplied with a LPC ISP(mini) adapter. I am using FlashMagic as the programming application.

I create a new project and select

- An executable for NXP LPC1700 and save as LED1

In common project settings I set

- Additional Output Format as hex (needed for FlashMagic)

I confirm target Proc as LPC1768 and Oscillator Frequency as 12MHz

Everything else is default.

After creating project I edit main.c

From

#include <__cross_studio_io.h>
void
main(void)
{
debug_printf("hello world\n");
debug_exit(0);
}

To:

#include <LPC17xx.h>

void
main(void)
{
    LPC_PINCON->PINSEL0 = 0x000000; //Configure the Pins for GPIO;
    LPC_GPIO0->FIODIR   = 0xffffffff; //Configure the PORT pins as OUTPUT
    LPC_GPIO0->FIOCLR = 0xffffff00;     // Make all the Port pins as low
    while(1)
    {
    }
}

I build successfully (Thumb Flash Debug)

Using Flash Magic, I transfer the Hex file to the Open1768 Board.

Transfer is successful with verify.

I press reset but the LED's on P0 Bit [0:3] do not light. They are wired to light when bit is low.

I cannot see what I am doing wrong. I have tried on two boards with two ISP Programmers to no avail.

I would really love to purchase the full licenced version of Crossworks but there seems little support for this CPU in respect to newbies.

Any help would be very appreciated.

Project files are attached

thank you in advance Mark

Set the PP define STARTUP_FROM_RESET and buy a JTAG cable.

Many thanks Michael, you are a champ, The STARTUP_FROM_RESET worked and with my LPC ISP Mini:)

JTag is on its way, as is the purchase of your compiler.

Note: I've searched the help files to no avail. Where is this documented?

Hi Mark,

You can buy any Discovery boards or Nucleo boards they are built with ST-Link for debugging and charging your code.
