Hi,

I bought LPCXpresso LPC1769 last week, but I have a problem with debbug my simple program:

#ifdef __USE_CMSIS
#include "LPC17xx.h"
#endif

#include <cr_section_macros.h>
#include <NXP/crp.h>

__CRP const unsigned int CRP_WORD = CRP_NO_CRP ;

int main(void) {

LPC_GPIO0->FIODIR = 0xFFFFFFFF;
LPC_GPIO0->FIOSET = 0xFFFFFFFF;

volatile static int i = 0 ;

while(1) {
i++ ;
}

return 0 ;

}

[B]Debbug message:

Cannot halt processor
02: Failed on connect: Ep(04). Cannot halt processor.
Emu(0): Conn&Reset. Was: None. DpID: 2BA01477. Info: WIN64HS12[/B]

What is wrong? What can I do?

Hi tarik1985, it is very simple, but ... First, you study hardly datasheet of LPC1769. It has about 800 pages, but It is funny ;)) Then study this PDF about LPCXpresso .

Good luck ;)

I have quite the same problem as masterboy has. My error message is:

Cannot halt processor
02: Failed on connect: Ep(04). Cannot halt processor.
Emu(0): Conn&Reset. Was: None. DpID: 2BA01477. Info: LPCLINK_1_1

I work with:

[LIST]
[*]LPCXpresso v5.1.0 [Build 2048] [2013-02-05] for Linux
[*]MCU: LPC1788
[*]project built by wizard: dummy C project for LPC177x_8x with CMSISv1p30_LPC177x_8x library (V1.3 (Jun 16, 2011))
[*]custom board with Cortex 10-pin header; schematic checked and seems to be correct
[/LIST]
I have not succeed to write any code into MCU, so it is still brand new.

What can be the source of the problem?

It's either hardware or software :rolleyes:

Did you use UART bootloader (and FlashMagic) to check your brand new board :confused:

Check it again, and again, and again until you find your mistake. Check power, check termination (esp RESET and ISP), check signal routing.

P2.10 (ISP mode pin) was floating and that was the cause.
Thank you for your help!
