Use nrf_fstorage_sd with nrf_sdh_ble_enable

[Automne]

Hi, I'm using SDK15.2.0 and A nRF52832 for my project.

I followed the "flash_fstorage" example give by Nordic, to write in the flash memory in my project. 

When I run my program the function nrf_fstorage_erase(&fstorage, address, 1, NULL); and nrf_fstorage_write(&fstorage, address, &data, sizeof(data), NULL); work perfectly but after I had called nrf_sdh_ble_enable(), the functions nrf_fstorage_erase() and nrf_fstorage_write() don't work anymore even if I don't use BLE.

The SVCALL is never called to write or erase the flash, I still stuck in nrf_fstorage_is_busy().

Do I need to change some priorities in sdk_config.h ?

Thanks, Automne

I double check, when the ble_stack is enable, I call nrf_fstorage_write(), the data are write properly in the flash but the SVCALL doesn't send me back the event NRF_FSTORAGE_EVT_WRITE_RESULT. That why I still stuck in nrf_fstorage_is_busy().

It's the same with nrf_fstorage_erase().

Thanks, Automne

Hi, 

Just to make sure, are you initializing Fstorage with the Softdevice backend (p_fs_api = &nrf_fstorage_sd;), and not nrf_fstorage_nvmc?

Thanks,

Hi Vidar,

I'm initializing p_fs_api with &nrf_fstorage_sd.

LOG ( INFO - NONE - 0 - SoftDevice is present.        INFO - NONE - 0 - Initializing nrf_fstorage_sd implementation)

Thanks, Automne

Hi,

I quickly modified the ble_app_hrs to use fstorage for writing one word to flash every time the battery_level_meas_timeout_handler() gets called, see attached. Can you try and see if it works for you, and if it does, try to see what you are doing differently? Note that nrf_fstorage_is_busy() may become "blocking" if called from an interrupt context, hence prevent fstorage from receiving flash events from the softdevice.

Thanks, you example is working, I'm investigating.
