Hi,

This time I encounter a problem when I'm trying to initialize debug,

Error is below:
Error Stopping at main.
Reason: Target request Failed: Function "main" not defined.

I'm creating my project from example projects of "mcb1700.code.bundle.lpc1769.lpcxpresso" and I'm just exchanging source files and header files with my sources and headers.

So, I wonder whether the mistake caused by creating project or writing codes?

Thanks in advance,

Best Regards,

It's 'creating project' :eek:

Obviously you are mixing old / new projects / files. It's a good idea to use examples to learn, but I prefer to create a new LPCXpresso project for own projects. So you are sure that you are using CMSIS2.0 and semihosting...

I'm importimg both CMSIS project and an example project from same example bundle.

Actually I tried to create my own project but I couldn't succeded :( So, I tried this way because it seemed easier.

No, I think I mislead you. Original Example is working well. And I want to use that example as template for my project. So, I'm deleting source files and header files of that example and replace with my own files. And than I got that error message.

Did you remove the source file containing main(). All C programs must have a main().

Yes I removed but my file also have main itself, but I think GNU debugger cannot see it :(

If clean and rebuild doesn't work, you've obviously changed something important :eek:

But, I tried this with different example projects and I change nothing except source code files and header files :(

I attached my source codes and header files, can anyone chech if problem is with my codes ?

Where is your cr_startup_lpc176x.c file :confused: Deleted :eek::eek:

Adding cr_startup_lpc176x.c,

disabling WDT_Init

//WDTInit();

and changing write / read buffers to real buffers seems to work here

//uint8_t * write_buf;
//uint8_t * read_buf;

uint8_t write_buf[50];
uint8_t read_buf[50];

Yes it works :) Thank you Zero :)

I thought that cr_startup is not necessary when I use cmsis, so this shows that I thougth wrong :p

But now I wonder that why do I disable wdt_init? how can I use wdt?

Debugger can't stop WDT, so just disable it during testing.

If you release your project enable it and use it to reset your LPC:

LPC_WDT->MOD = WDEN | WDRESET;
