How to start a new project that supports Flash Download and Erase

The above page may help.
Basically, you need to configure the [Debug] and [Utilities] tabs correctly.

But, LPC23xx is old, maybe you should start with some Cortex-M MCU, like LPC17xx/LPC13xx/LPC11xx.

Thank You John, I have followed the instructions given on this webpage completely I think.

I see the following pop up when I try to download to flash.

checked boxes

* use target driver for flash programming
* use Debug Driver
*update target before Debugging

flash download setup

*erase sectors
*program
*verify
*reset and run

At the moment I am also getting this error which I am trying to figure out.

main.c(76): error: #20: identifier "T0_IRQHandler" is undefined

The files in my project at this time are:

LPC2300.s

main.c LCD.h LPC23xx.h stdio.h

strcopy.s
Retarget.c
IRQ.c LPC23xx.h

LCD_4bit.c

Serial.c

I found that I had commented out the following lines in main.c

extern __irq void T0_IRQHandler (void);
extern __irq void ADC_IRQHandler (void);

That got rid of the error I was getting.

Then I have had partial success:

I am able to download to flash.

But I am not able to erase the flash for some reason.

I notice when I download to flash it automatically erases the flash first.

My question now is how can I get the IDE menu option to erase to flash to work.

Also, I have recently bought some newer ARM boards. But I am interested in learning/exploring
how to program ARM7TDMI-S ARM instruction set assembly right now.

Sounds like you can download and debug your LPC23xx; but fails to do a separate erase.
If so, your [Debug] tab configuration is correct; but [Utilities] tab configuration is not.

Hi John, Looked at the Utilities area. Can not see a difference with other projects in this
pop up area. I am happy though that I can download to flash and it erases when I do that.
Thanks for your help, Gary
