bootloader_secure related

[air]

 Hello,

 

I am using nrf51822 / SDK v12.3 / SD 130.

I want to change the FW of the sold product to a new FW.

The bootloader address / length of the two are the same, and the secure key (*.pem) is different.

 

I’m trying the process(FW 1 -> FW 2-> FW 3).

 - FW 1 : FW of the sold product

 - FW 2 : hw / fw / some signature information ignore in dfu_req_handling.c  and FW 3 secure key add

 - FW 3 : FW to be changed

 

DFU  to FW 2 works, but it seems to show a secure key related error in the DFU to FW 3 process.

Here, I ask if there is any way to pass without referring to the secure key information.

 

 Thnaks.

Hi,

but it seems to show a secure key related error in the DFU to FW 3 process.

What is the error? Please provide the log. 

You should use the same pair of the key for the boolader and updated package.
