Migrating from SDK11 TO SDK17

[YuvalShavit]

Hi, 

I migrated my software from SDK11 TO SDK17

(Changed the BL + SD + APP)

Now i want to upgrade to (SDK17) old units (with SDK11) in the field.

Do you have any advise how to do that ?!

(i Tried many hours asking the AI but failed so far....

The AI said to migrate it in 2 phases - the BL and SD toghther and declare them as APP (because of size problems) , but i didn't sucseed doing that)

Hope there is a way to do that.....

No idea what AI was hallucinating here.

The memory layout - especially the bootloader location and reserved sector count - need to match exactly to you old application. Don't remember whether that is possible in the first place and will likely need manual configuration.

The other condition is that new SD+new BL must fit in the slot space for the app. Could be rather tight in the NRF52832 depending on which SD you intended to use.
