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[].

Logging over UART should be enabled by default. Are you working with a Nordic development kit?

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?

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

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)

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?

Hi

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.

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?
