Where to check NRF_EVT_FLASH_OPERATION_SUCCESS?

[Justin]

Hi Tech Team,

I am using nRF52832 chip and the recent soft device(SD). I want to implement my own file storage and thus using sd_flash_write () andsd_flash_page_erase functionalities of soft device.

I want to check for the success of read or erase? From documentation I understand that the events NRF_EVT_FLASH_OPERATION_SUCCESS and failure events will be generated depending upon the operation. I want to understand where this events will be generated and how to check it? Pointing to any example code would help a lot.

Thanks,

Justin

Hi Justin

Please take a look at the flash_fstorage example and the fstorage_evt_handler function (line 169).

Best regards,

Simon

Hi Simonr,

Thanks for your reply. 

My intention is not to use fstorage or any sdk level API. I wan tto use SD level sd_flash_write() and sd_flash_page_erase functionalities and thus incorporating NRF_EVT_FLASH_OPERATION_SUCCESS and NRF_EVT_FLASH_OPERATION_ERROR.

Please point me to the example or implementation of these events.

Thanks,

Justin John

Hi Justin

The flash_fstorage example will use the SoftDevice level functions sd_flash_write() and sd_flash_page_erase() functions if the SoftDevice is present by way of the nrf_fstorage_sd.c and nrf_fstorage_sd.h files. You can modify the example to call the sd_flash functions directly as well if you'd like. In that case, you can take a look at the nrf_fstorage_sd.c and nrf_fstorage_sd.h files to see how these functions are implemented.

Best regards,

Simon
