s110/s120 and blank .ld files

[bishop]

Hello! I'm trying to program nrf51822 like a BLE device. I'm using QT Creator + GNU Compiler + Open OCD + STlink(debugger) to create and program. If I choose "gcc_nrf51_blank_xxaa.ld" like linker script file, I can to debug and to blink leds. But If I choose "gcc_nrf51_s110_xxaa.ld" I can't to blink leds, and can't to debug my program. Can you tell me what the differ between "gcc_nrf51_blank_xxaa.ld" and "gcc_nrf51_s110_xxaa.ld". And what I must to do if I want to create BLE device?

blank is used with bare nRF51 chip (it runs as a pure ARM Cortex M0), s110 used when S110 soft device (BLE stack) is programmed in flash memory.

To create a BLE device start with ble_app_template in SDK examples dir.

-c

Thanks for answer. Can you tell me, how can I program s110 soft device in flash memory? I'm trying this:

1. From examples I get "ble_app_template_s110_xxaa.hex" file.

2. Tries to program flash with it via open ocd.

3. Resets chip.

Nothing happens.

I modifyed example(main.c file) like this (led has pin9):

...
    void func_mig()
    {
        nrf_delay_ms(500);
        nrf_gpio_pin_set(9);
        nrf_delay_ms(500);
        nrf_gpio_pin_clear(9);
        nrf_delay_ms(500);
    }
    
    /**@brief Function for application main entry.
     */
    int main(void)
    {
        nrf_gpio_cfg_output(9);
        func_mig();
        nrf_delay_ms(2000);
        func_mig();
        func_mig();
        // Initialize
        leds_init();
        timers_init();
    ...

But if I programs this code with blank .ld files, I can toggle on/off with Leds.
