Problem is solved. It was related to RAM area assignment. Changed from

\MEMORY
{
  RAM (rwx) :  ORIGIN = 0x200013c8, LENGTH = 0x6c38
}
I changed to
\MEMORY
{
  RAM (rwx) :  ORIGIN = 0x20001fe8, LENGTH = 0x2018
}

I got soln in other thread.

Are you referring to the code in your comment on July 23rd? Or are you referring to a SDK example?

I checked on mbed compiler and voila !!! it is working. I flashed local with/Without Softdevice but is not working after compiling code from SDK. But if i compile the code on mbed compiler and flashed then it starts working. What went wrong from SDK and compling?

Hi, I program the chip with verify option and it gave me "Verify OK" result. So, i think program might have flashed correctly. here are registers status i got from chip.

> reg

PC is not all changing. means chip is not running.

Could you read back the flash of the chip and verify that the hex was written to the correct location and diff the readout with the original hex?

Hi, I am using SDK v12.2. I tried Blinky example. Even that one is also not working. I have posted my code in above post. When i was trying peripharal code that time i was flashed SD as well.

Which SDK version are you using and did you flash the SoftDevice when you tested witht eh ble_app_uart example?

I recommend that you start testing with a simple peripheral example like the blinkey example found in nRF5_SDK_12.2.0_f012efa\examples\peripheral\blinky\pca10028\blank

Hi, Now I am able to flash the hex file to NRF51822. But code is not working on chip. Is there any parameters need to define? I tried Led Blinking and ble_peripheral/uart example. But not working, Any clues? Hete is my code.

#include <stdbool.h>
#include <stdint.h>
#include "nrf_delay.h"
#include "boards.h"

#define LED1    6

/**
 * @brief Function for application main entry.
 */
int main(void)
{
    /* Configure board. */
        NRF_GPIO->PIN_CNF[LED1] |= GPIO_PIN_CNF_PULL_Pullup << GPIO_PIN_CNF_PULL_Pos; // Set pullup
        NRF_GPIO->DIRSET = 1<<LED1;
    /* Toggle LEDs. */
    while (true)
    {
        NRF_GPIO->OUTSET = 1<<LED1;
        nrf_delay_ms(1000);
        NRF_GPIO->OUTCLR = 1<<LED1;
        nrf_delay_ms(1000);

    }
}

Current OpenOCD version is 0.10.0. You should update.
