yes after softdevice enable, because i enable the softdevice in ble_stack_init. in my case the 11th step in my main is app_timer_init, here is my main structure:

    uint8_t advhandle= BLEHandler::advHandle;

    // Initialize.
    log_init();
    timers_init();
//    power_management_init();
    ble_stack_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init(true);
    conn_params_init();
//    peer_manager_init();
	advertising_start();


    // Start execution.
    NRF_LOG_INFO("Drone is Ready.");
//    application_timers_start();


//    advertising_init(false);

//    Leons Code
//	NRF_LOG_INIT(NULL);
//	NRF_LOG_DEFAULT_BACKENDS_INIT();
//	lfclk_request();
	app_timer_init();

The Softdevice will eventually invoke the error handler if you halt the CPU while it's enabled. Where is step 11 in your code? After Softdevice enable? In any case, I would recommend that you try to get debug logging to work. It makes debugging your code much easier.

Thanks for your suggestion i can build my program for now, but still i can not find the device or it becomes unnamed (i recognize it because the message it sends) and as i debug it, it hit nrf_breakpoint_cond after 11 steps.

There were a couple of typos in your RAM configuration. Try:

RAM (rwx) : ORIGIN = 0x20004000, LENGTH = 0x3C000

This linker error should not be related to the NRF_SDH_BLE_VS_UUID_COUNT setting. Did you update the linker script before this happened? Can you upload it here?

ah ya thank you i forgot to set to 1,

but now i got this problem

"d:/drohnenprojekt-umgebung/gcc-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/bin/ld.exe: _build/nrf52840_xxaa.out section `.data' will not fit in region `RAM'"

"d:/drohnenprojekt-umgebung/gcc-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/bin/ld.exe: region `RAM' overflowed by 4294730225 bytes"

i guess my ram to small what should i do?

I guess that you may have to increment NRF_SDH_BLE_VS_UUID_COUNT in sdk_config.h. The NUS service adds one 128-bits vendor-specific base UUID. NUS init should return 0x4 (NRF_NO_MEM) if that's the case.

I've solved the problem with global error, now as I implement the nus (add custom service) my device is not found, as i debug it the program stop at service_init and go to nrf_breakpoint_cond.

Can you try to place a breakpoint right after the call to nrf_sdh_ble_enable() in ble_stack_init() and check what the returned err_code is? Or does it fail before it reaches this line?

honestly said, I'm using Laird ble654 integrated with NR52840 chip.

[quote userid="4240" url="~/f/nordic-q-a/57787/how-to-define-the-right-ram-or-flash/234573"]Have you set up any debugger integration with Eclipse so you can step through the code? [/quote]

I think I hv JLINKRTT logger. and I already installed it to eclipse but as i debug it it just go to nrf_break_cond after timer_init it didn't go through ble_stack_init here is my structure:

    log_init();
    timers_init();
//    power_management_init();
    ble_stack_init();
    gap_params_init();
    gatt_init();
    advertising_init();
    services_init();
    conn_params_init();
//    peer_manager_init();
	advertising_start();

    // Start execution.
    NRF_LOG_INFO("Drone is Ready.");
/

and LED on board signs these 3 problems:

#define NRF_ERROR_SOFTDEVICE_NOT_ENABLED (NRF_ERROR_BASE_NUM + 2)

#define

NRF_ERROR_NO_MEM (NRF_ERROR_BASE_NUM + 4)

#define NRF_ERROR_INVALID_STATE (NRF_ERROR_BASE_NUM + 8)

Any error passed to the APP_ERROR_CHECK() macro will lead to this. So we need to find out what the error code is and where it was returned. Have you set up any debugger integration with Eclipse so you can step through the code?

hmm I dont think I have, how can I enable it in eclipse?

honestly I dont hav any problem while flashing and debugging but the LED board sign that i have a global error that i don't have enough memory

Is there any other possibilties why i can find my device via smartphone?

that happened after i change the m_adv_uuids[].

Hi,

Do you have debug logging over UART or RTT enabled? The log should inform you if you need to allocate more RAM to the app, and in that case, how much.

Best regards,
