DFU-Implement. crashes after exec. of ble_dfu_init()

[Uwe]

My problem: The run of my 1. DFU - Implementation delivers an error code after executing the line "err_code = ble_dfu_init(&m_dfus, &dfus_init);". For my opinion this is caused by reservice_uuid.type = 0. The parameter of my application are the following:

nRF52832, S132, SDK11.

The function is called in the suggested order in the function static void services_init(void):

memset(&dfus_init, 0, sizeof(dfus_init));

dfus_init.evt_handler   = dfu_app_on_dfu_evt;
dfus_init.error_handler = NULL;
dfus_init.evt_handler   = dfu_app_on_dfu_evt;
dfus_init.revision      = DFU_REVISION;

err_code = ble_dfu_init(&m_dfus, &dfus_init);
APP_ERROR_CHECK(err_code);                                 --> RESET

The initialization and advertising of an second own service works fine. What did I do wrong?

The function sd_ble_enable(&ble_enable_params,&app_ram_base) with a false initialized second parameter -&app_ram_base- caused the problem. With the definiton of app_ram_base = APP_RAM_BASE (add. 0x20001900 length 0x00000004) the fault disappered.

Hi Uwe, I assume you have managed to solve the issue ? Note that you should always check for the returned err_code as it will point out what cause the issue. app_ram_base should be modify according to the configuration of the application for example number of central link, peripheral link, bandwidth, etc. If it doesn't match, you should check the value returned value of app_ram_base when calling sd_ble_enable().
