fstorage write& Erase Interrupt not Triggered when BLE Init Called

[GSV R&D]

I have written a word (32 bites) in 0xFF000 using nrf_fstorage_write(),  When BLEInit(), nrf_fstorage_evt() callback not trigged, 

BLE_Sleept()

nrf_storage_write()

BLE_wakeup()

Hello,

The Softdevice reserves access to the NVMC peripheral so you can't write directly to its registers directly. Doing so will trigger a fault exception, see Memory isolation and runtime protection.  So, to prevent the system from halting, you need to select the SoftDevice backend for fstorage and remove the write accesses to "NRF_NVMC" in your code.

Hi,

Sorry for the delay, Thank you for your reply. I have changed the code as follows: 

nrf_fstorage_api_t * p_fs_api;
p_fs_api = &nrf_fstorage_nvmc;  -- I have changed to  p_fs_api = &nrf_fstorage_sd; 
iDebug("fs Init started.");
nrf_fstorage_init(&my_instance,/*fstorage instance,previously defined. */
p_fs_api, /* Name of the backend. */
NULL /* Optional parameter, backend-dependant. */
);

But I could not see any improvement.

Can you share , if i have missed any point that you have given

I cannot tell what the program flow is based on the code snippet you posted. Can you upload a minimal version of your project so I can try to run it here?

Have you performed any debugging to see if the program gets stuck or crashes?
