Can I get the maximum no of words can be written to flash by using sd_ble _flash_write API function in nrf52

Hi,

I want to write calibration and configuration datas in to flash and read it back. By using sd_ble _flash_write API function , I can write up to 520 words(520* 4 bytes) . When I increased the size to 1000 or above the datas are not written in to flash. Can anyone knows what is the maximum no of word length we can pass it in sd_ble _flash_write API function . In infocenter.nordicsemi.com/ it states that I can txit up to 1024 word for nrf52. But I am not able to txit that many word.

What flash start location are you using when you are trying to write 1024 words? I don't think you can exceed a page boundary with a write, so the start location has to be at the start of a page.
