how to define the right RAM or FLASH?

[Andhika]

HI 

I'm writing a programm the using a nus as its service, because nus is a custom service there is something that need to be changed, I followed the tutorial about making a custom service and that being said that we need to change the RAM, but my starting RAM is actually bigger than the ram from the tutorial so it should be save right? but problem is I can not find the divece as i scan it with my smartphone.

basically fisrt I'm using ble_template as my base for establishing connection and then add the nus custom service according the tutorial.

my guest is that the problem lies in starting ram. is there any possibility to know tha right starting ram in eclipse?

best regards,

Andhika

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.

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[].

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.

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?

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?

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

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

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.

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.

[Andhika]

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();
