Hi,

flash_word_write is a function defined in the flashwrite example in the SDK, this is not related to the use of sd_flash_write & sd_flash_erease. How are you trying to use the functions? Are you using them in a softdevice project?

Best regards,
Jørgen

How do you check that nothing is written to flash? Return code of 0 means that the function call was successful (NRF_SUCCESS). Note that the sd_flash_page_erase and sd_flash_write functions are not blocking, the softdevice will try to schedule the erase/write between BLE events. You should wait for the NRF_EVT_FLASH_OPERATION_SUCCESS event before the operations are completed.

I am checking it with the debugger... the flash adress is FFFFFFFF after erasing.. and  is the same after writing

How can i wait for NRF_EVT_FLASH_OPERATION_SUCCESS  event ?
