What is Erase & write in Nrf Connect doing

[Michal]

Hi,

I am working with Nrf Connect's programmer application and I was wondering what button `Erase & write` is actually doing. Is it erasing all memory on nrf or maybe only pages that will be programmed - like `nrfjprog --program .hex --sector-erase` ?

Thanks,

Michal

Hi Michal, 

'Erase & write' clears the written memory and programs the files added to the File Memory Layout. It dosn't erall all the the memory.
