Completely wipe flash?

[q]

Hi,

Does the erase target in the makefile completely erase the flash? I'm having strange errors when trying to read the flash (i.e. I can't read anything from flash, even though I could a couple days ago.). I want to make sure the problem is with my code and not some unexpected error with the fds library (encountering an error while a file is open, creating multiple files with same ID, ect.).

Thanks SDK13 nrf52832 pca10040

You have not said what OS etc you are using, but on Windows you can use

Nrfjprog to erase the whole MCU

Thanks Bjørn

BTW.

I think @q changed their question.

But in case they want to erase the whole of flash memory they can use

nrfjprog --erase

Re: Makefile .

make flash does not erase all flash, it only does the pages needed for the application
