Flash write/read in nrf52840

[rajAsthana]

I want to write a data stream coming over UART into flash memory of the nrf52840 & echo it back after writing it to flash .

Please suggest from where i can start ?

Thanks

Hi,

I would suggest that you start by looking at the Flash Data Storage Example in the SKD. This provides a command-line interface that you can use to write and read data to and from flash.

Best regards,

Jorgen, The problem with the examples is that they skip the hardest part - finding where one can write. The example just puts the start address at the last page. What good is that? How about a method that one can use to find the start of free flash in case one needs more than 1024 bytes? For me that has been a real blocker as I have yet to find any documentation on how to do that.
