No problem, I think it is just me who is easily confused :)

I guess our documentation can be a bit lacking regarding this. If you want to store that amount of data though, you'd certainly need external flash. Have a look at this. nrfutil device would also be the recommended approach, instead of nrfjprog, though the docs also get into that part.

Does this help clear things up?

Hi,

sorry for being not so clear. What I refer to is the external flash used to store application data, not the firmware. In our case those data are made up of a quite large amount of configuration items (images and audio files), around 5-6 MB. We would to store them , if possible, during the initial setup of device in our factory. I read some posts saying that a possible way to do that is using the cmd nrfjprog but not sure if this is the right way..

I hope now my request is more clear.

Thanks

Hi,

Could you expand a bit on this? I am not sure what you mean here. Flash is just a local concept, although you can fill the flash using wireless. Are you talking about flashing the devices? Is this info device specific?
