how do you attach to a running program? I am using lpcxpresso 6.1.4 and the target is a lpc1113/302.

In FAQ there is a topic on this and when i go to edit launch config, the debugger tab is different. There is no target tab and no place to change the attach setting.

what am I missing?

You have chosen a "C/C++ Application" instead of the "C/C++ (NXP Semiconductors) MCU Application", which is why you see a different configuration.

The simplest way to create this is:
1. Delete your existing launch configuration
2. Create a new C/C++ (NXP Semiconductors)..." launch configuration

And edit it as described in the FAQ. We will update the FAQ to make this more obvious,

Great that works.

I'm using the secondary bootloader to load another program. Now that I load the debug session, I find I'm in the NMI handler. I put a while(1) at the start of my main but i don't get that far.

So how do I trace- find out where I go wrong in the cr_startup_lpc11 startup code?

Hi internav,
Please put breakpoint in the function ResetISR(void) in file cr_startup_lpc11.c . The debug using step by step approach.

Hi,

I don't see how this will work. The code is loaded in flash with secondary bootloader. so i power up and attach with emulator, and i'm already dead.

Hi internav,
Could you please explain in details about your program flow? I think it is not there in your post. I suppose you are jumping to secondary bootloader after some time.
Any way for better help and support please post details.

Hi,

My mistake, the flash was corrupt.

Now with the secondary bootloader and my program in flash, I can attach and debug.

But now the uart interrupt routine returns to neverland. If my program is linked with the default script, ir runs fine in standalone mode. With my script, it returns wrong. here are the script files. The code begins at 0x2000 and the bootloader has been changed from the normal 0x1000 to 0x2000 for the redirection.

added later:

I am using the system tick and that interrupt works fine. Neither the systick or uart isrs are used in the bootloader.

tell me what other details you want.
