Fstorage erase/write event callback function not invoked

[Mk187]

Hi,

 I am using fstorage api and for write and erase operations I am not receiving events. The event callback function is not invoked. I am using SDK 16.0.0.

In the sdk_confic.c the below macros are enabled

NRF_SDH_ENABLED

NRF_FSTORAGE_SD_ENABLED

NRF_SOC_ENABLED

Soft device is enabled in my application. I checked the map file nrf_fstorage.c, nrf_fstorage_sd, nrf_sdh_soc.c, nrf_sdh.c, nrf_sdh_ble.c  are included in the project and compiled. 

What am I missing in the setting? Could you help me to fix this problem?

Thanks.

NRF_SDH_ENABLED

NRF_SDH_SOC_ENABLED

NRF_FSTORAGE_ENABLED

In the above post I got macros wrong

Hi, 

• Have you checked that nrf_fstorage_init() and nrf_fstorage_write() actually returns NRF_SUCCESS?
• Can you share the part where you initialize the fstorage module? 
• Try to increase NRF_FSTORAGE_SD_MAX_WRITE_SIZE and NRF_FSTORAGE_SD_MAX_RETRIES

Thanks, Jared. The above issue is resolved. I was calling fstorage functions when interrupts are disabled. So, fstorage call back function wasn't catching the events.

I have one more question. I am using nrf_fstorage_sd as a backend. so If softdevice is not enabled/initialized then calling fstorage to erase and write function will create any problems? Like throwing exceptions, or nrf_fstorage_is_busy(p_fstorage) always returning true, or write/erase events don't happen.

 Ok, great that you found the solution.

The Softdevice backend can be used as long as the Softdevice is present, the Softdevice doesn't need to be enabled.

Thank you.

I am facing one issue. I am writing to two pages - address 0x77000 and 0x78000. First writing to 0x77000 and then 0x78000. For 0x78000 page write, I am not receiving events. Sometimes erase event happens, but not write. And I don't have any issues with 0x77000 write. I thought the fstorage queue size might be the problem. So I increased the queue size to 16. Still having issues. Can you think of any reason for this behavior?
