SDK 10 System and PStorage Callback Issues

[Dave_couling]

I've migrated over my application code. I've noted that SDK10's new modules causes much high RAM consumption than on SDK 6.1. Everything is working however, except for the Flash Settings Module. My code crashes upon trying to load values from Flash. The debugger simply loses track, and app_error_handler() doesn't catch anything.

I noted that my cb_function seems to be called properly receiving the correct PSTORAGE_LOAD_OP_CODE. However I also noted that the sys_evt_dispatch() not called at all. So I not receiving System Events. I properly register for them using:

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

So I'm struggling to figure out why this isn't working, as according to the documentation this hasn't changed much since SDK 6.1. Thanks in advanced for the help guys.

pstorage_load() will call the cb_function with the PSTORAGE_LOAD_OP_CODE directly and not generate a System Event. This is because pstorage_load() does not use the SoftDevice Flash API like pstorage_store and pstorage_clear. It simply returns a pointer to the address where the data is stored in flash without going via the SoftDevice.

Just to add a wrap up comment, the reason my Flash module was failing was during Loading the Source variable size was not set to [PSTORAGE_MIN_BLOCK_SIZE] but instead [2] which did not match. This wasn't an didn't cause any issues in SDK 6.1, but correctly is in SDK 10
