Hello,
when I wrote my code and then Debug (click from quickstart panel) I get error in attachments.

Which version of LPCXpresso are you using?

And what target MCU and which debug probe?

And please post your debug log:

https://www.lpcware.com/content/faq/lpcxpresso/debug-log

It would also be worth booting the MCU into ISP mode before starting the debug connection...

[As a slight aside, as you have posted this into the LPC12xx forum, you are probably using a part in this family. In which case, you might also want to read this FAQ - https://www.lpcware.com/content/faq/lpcxpresso/lpc12-watchdog ]

Regards,

And did you follow this FAQ for regaining debug access?

Yes I'am go to Launch configuration and then Debug tag and set Vector catch on true.
Now working.

But I have a bug in my code. If I debug LED blinky it's OK, when Debug my program I have an Error.

#ifdef __USE_CMSIS
#include "LPC122x.h"
#include "IO.h"
//#include "lcd.h"
#endif

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

int k = 0;
uint16_t bits[10];


void I2CInit(){
LPC_SYSCON -> SYSAHBCLKCTRL = (1 << 5);
LPC_I2C -> CONSET = (1 << 6);//config CONSET (MASTER OR SLAVE)
LPC_IOCON -> PIO0_10 = (1 << 2);//SCL config
LPC_IOCON -> PIO0_11 = (1 << 2);       //sdA CONFIG
}

void I2CSend(uint8_t bit){
//LPC_I2C -> CONSET = (1 << 5);
LPC_I2C -> DAT = bit;
}

void DataSet(){
bits[0] = 0xA2; //slave addres
bits[1] = 0x0;//set pointer to zero position in register
bits[2] = 0x2;//set 12hour mode and 7pF quartz
//-************************************************************************
bits[3] = 0x4;//set pointer to a second register
bits[4] = 0;//sekunde
bits[5] = 0x45;//minute
bits[6] = 0x23;//hour
bits[7] = 0x15;//days
bits[8] =0x4;//weekdays
bits[9] = 0x12; //month
bits[10] = 0x11;//year
}


int main(void)
{
DataSet();
I2CInit();
//start condition
LPC_I2C -> CONSET = (1 << 5);
for(k = 0; k <= 2; k++){
I2CSend(bits[k]);
}
//restart condition
LPC_I2C -> CONSET = (1 << 5);
I2CSend(bits[0]);
for(k = 2; k <= 10; k++){
I2CSend(bits[k]);
}
LPC_I2C -> CONSET = (0 << 5) | (1 << 4);

while (1)
{

}
}

In a disassembly viewer I get:

05db2380:   Failed to execute MI command:
          -data-disassemble -s 98247552 -e 98247660 -- 3
          Error message from debugger back end:

Something in your code is causing a HardFault - the PC is 0x5db2380 which is non existing memory.

Having looked more closely at your code, in I2CInit, you are enabling I2S but DISABLING everything else (including flash). You need to OR in the enabling of I2C.

Thank you.

Now I set

LPC_SYSCON -> SYSAHBCLKCTRL |= (1 << 5);
LPC_I2C -> CONSET |= (1 << 6);//config CONSET (MASTER OR SLAVE)
LPC_IOCON -> PIO0_10 |= (1 << 2);//SCL config
LPC_IOCON -> PIO0_11 |= (1 << 2);       //SDA config

It's OK?
