[quote user="hu-yang"]Is it possible to upgrade when the network core image size small than 256-8=248KB? [/quote]

Yes, that is correct. I had the flash size wrong in my previous comment. 😃

Hi,

Thanks for your reply. AS nRf5340 datasheet shows flash size is 256KB, and ram size is 64KB. Is it possible to upgrade when the network core image size small than 256-8=248KB?

There seems to be extra flash memory capacity for application to use.

Since your approach is to update both the cores at the same time, this method is possible, i.e. changing (or upgrading) from one to another, as long as you have enough memory.

We would recommend using external flash to support this configuration to ensure that you'll be able to upgrade the application core with a larger application instead of splitting the application core flash.

Also if the network core image size > (64KB(network core flash size)-8KB(network core bootloader))=56KB for the full BLE stack on network core it will not be possible to upgrade to full BLE stack.

Hi,

Sorry for the delay. This is because it's the vacation period here and many are on vacation. Still waiting for a response.

Hi priyanka:

Is there any answers?

Hi,

Both of them are two options and there is no option of one being better than the other (since you mentioned upgrade). It should be possible to use both but I have asked internally regarding this and will get back to you with an answer.
