Softdevice 7.0/7.1 hangs on sd_softdevice_enable

I am still having other issues with SD7, I am not getting the BLE_EVT_TX_COMPLETE event anymore either which breaks my custom service. However, this question is answered and so I will open another thread for my other problems.

I must say, upgrading from one version to another is quite aggravating...

No, I can't seem to set a breakpoint anywhere. No matter what I do, it falls into this trap if I have the debugger attached.

I will try more tomorrow, at least my code can run again. Thanks for all your help!

Were you able to break at the beginning of main or in the Reset function at all ? There is a different between SD6 and SD7. It crashes when I first tried SD7 moving from SD6. So I compared the sample code between both versions and found that init is different. Also bond manage is replaced by device manager.
Important, must do a clean before recompile in SD7.

Ok, that does seem to fix the issue. However, I cannot attach the debugger at all now. If I use your code and just power on the board, things work fine. But if I try to attach the debugger (even with no breakpoints), it will still get caught in this same spot and hang.

I checked, the old init function still would not work even without the debugger attached. This was also not the same behavior I had in SD6. At least there, I could run with the debugger attached (and generally had issues when I tried to place a breakpoint). Is there something different in SD7 that prevents the debugger from working?

This is the new init sequence for SD7

static void ble_stack_init(void)
{
    uint32_t err_code;

    // Initialize the SoftDevice handler module.
    SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, true);

    // Enable BLE stack

    ble_enable_params_t ble_enable_params;
    memset(&ble_enable_params, 0, sizeof(ble_enable_params));
    ble_enable_params.gatts_enable_params.service_changed = IS_SRVC_CHANGED_CHARACT_PRESENT;
    err_code = sd_ble_enable(&ble_enable_params);
    APP_ERROR_CHECK(err_code);

    // Register with the SoftDevice handler module for BLE events.
    err_code = softdevice_ble_evt_handler_set(ble_evt_dispatch);
    APP_ERROR_CHECK(err_code);

    // Register with the SoftDevice handler module for BLE events.
    err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
    APP_ERROR_CHECK(err_code);
}
