nrf9160 flash

[amelio]

Hello, I would like to know if the nrf9160 flash can be loaded locally and not via wireless. We have a lot of devices with data to preload and is unviable to download the data from network as it takes 40 minutes for each device

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?

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

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?
