USBD with FreeRTOS not work

RE: USBD with FreeRTOS not work

I checked the code, SoftDevice still does not work.
The application crashes to err_code = nrf_sdh_ble_enable (& ram_start);

where error code = 4

NRF_LOG_WARNING("Change the RAM start location from 0x%x to 0x%x.",
app_ram_start_link, *p_app_ram_start);

I change ram start address from 0x20002A98 to 0x20002AB8 (*p_app_ram_start)

and now it worked!!! =))

Maybe someone will come in handy this solution.

And thanks for the sample code! =))

Please remember to set NRF_SDH_DISPATCH_MODEL to 2 in the sdk_config.h for the example above to work.

Thank you! I will check as soon as possible. Now I have USB working with RTOS, but does not work BLE, I hope an example of your code will help solve the problem

Hi, this is part from pre 15.1 repository.

First of all you have to change nrf_drv_power.c file a little. We could not do it, but it helps to write clean code next:

ret_code_t nrf_drv_power_init(nrf_drv_power_config_t const * p_config)
{
#ifdef SOFTDEVICE_PRESENT
+    if (m_initialized)
+    {
+        return NRF_ERROR_MODULE_ALREADY_INITIALIZED;
+    }
    if (nrf_sdh_is_enabled())
    {
        return NRF_ERROR_INVALID_STATE;
    }
#endif

Then the main.c goes:

devzone.nordicsemi.com/.../4150.main.c

Do I understand correctly that I should initialize everything in the same way as in individual examples, but in the same project?
Do I need to call the app_usbd_event_queue_process () function?
The application falls into error when you call this function

Can you give a piece of sample code? Only main.c file

How to solve this problem? What methods of USB need polling for working with FreeRTOS?[/quote]

This is not a problem. See the description of NRF_SDH_DISPATCH_MODEL_POOLING:

/**@brief   SoftDevice events are polled manually using @ref nrf_sdh_evts_poll().
 *
 * @note    In this mode, a user application can also implement SD_EVT_IRQHandler() to receive a
 *          notification about incoming events.
 */
 #define NRF_SDH_DISPATCH_MODEL_POLLING    2

This is not an USB requirement - it is an SDH implementation in FreeRTOS. This configuration is required for SDH module to remove interrupt implementation. It means that after that you may use pool to check the SD status or you may implement your own interrupt implementation. This is something that is done inside nrf_sdh_freertos.c.

We are going to provide an example with SoftDevice, together with USBD and working using FreeRTOS.

Sure. Here: http://rgho.st/7PcBJKX2Q

And my libraries for project: http://rgho.st/private/8mhvk2yXk/e0a5f691880aaa4ff4f71db085b0ba93

Inside the project assembly with FreeRTOS, without FreeRTOS and bootloader.

At the same time the question about Bootloader:

why does not the part of the periphery work in the bootloader (BLE, USB, Timer)?

USB - The controller restarts when the function app_usbd_event_queue_process() is called (only when cable connected).

Timer - The controller restarts when triggered interrupt from the timer.

BLE - When BLE stack initialization (ble_stack_init()), it gets into the svc_handler () of which there is no implementation of the handler.

The initialization is the same as in the main program, I use the same files from my libraries nRF5x_LIB15

Is it possible to attach the project to this case? we can make it private case if you think it is necessary to share the code?
