Latest status of Buttonless secure DFU in SDK 13.0

[sam wagner]

Hi,

I just got the email about SDK13.0 official release. The list of changes in this release include "Secure DFU improvements". What does it mean? Is Buttonless Secure DFU completely supported in this release?

Regards, Sam

Hi, As Bootloader address is not changed,Can I update bootloader+SD+APP from SDK 12.0.2 to SDK 13.0.0?

@Srikar: What do you mean by "As Bootloader address is not changed" ? It is changed in our current example in SDK v13.

I don't see any problem update bootloader+SD+APP from SDK 12.0.2 to SDK 13.0.0.

@Hung Bui,Means Bootloader IROM starting address 0x78000 and size 0x6000 is same in SDK 13.0 and 12.0.2. In my case DFU update (secure BL+SD+APP) from 12.02 to 13.0 is failing even other private keys are same but DFU updates are working for without issues from 12.0.2 to 12.0.2 and 13.0 to 13.0 .

Could you open a new case and give all description there ? please try to test with only BL+SD first.

Hi, Has there been any progress on this issue with SDK 13? I see that you had indicated something happening in the March or April time frame. Like Sam, we would like to support sharing bonding between the app and the DFU.
