Secure DFU serial bootloader

[Erwin v. H.]

I'm busy implementing a (serial) DFU host, but sofar i'm unable to send a proper init packet.

The bootloader keeps returning an invalid signature error

If i open a .dat file with HxD is the visible data also in the order that it has to be send or do i have to modify this?

Yours sincerely,

Erwin

Hi,

What version of the DFU bootloader is on the DFU target, based on what version of the SDK?

How do you generate the DFU update package?

Are you using Secure DFU, and have you signed the update using the correct private key?

Regards,
Terje

Dear,

Do you have any idea how i can continue.

As is said i currently always get a signature error after sending the init packet.

Do i have to search it in the method of sending or in a mismatch of signature/private key between the generated package and bootloader?

Regards,

Erwin
