Hi Bjorn, I saw your new answer. First I try the New DFU function in sdk12.3 because my project is nRF51. I think this New Dfu is very good. and I think I will stop to try implement old dfu into my old project.

Thank you very much.

On second thought I think you should use the S110 Dual Bank Bootloader from SDK v10.0.0, see my edited answer.

Ok, I will think about how to move sd310 project to sdk 12.3.

Thanks

Hi Vincent,

the bootloader with signing from SDK v10.0.0 was an experimental implementation and is not intended for use in a final product.

The production-ready implementation of our Secure DFU bootloader was added in SDK v12.3.0, but this SDK does not support the S310 (The last SDK that supports it is SDK v10.0.0).

Migrating the S310 project to SDK v12.3.0 should be possible, but it will involve compiling the S130 secure bootloader project againt the S310 headers and the API has changed a lot from the S310(based on the S110 v8.0.0 API) so there might be a lot of conflicts.

I think the easiest solution is to use the Legacy S110 Dual Bank Bootloader from SDK v10.0.0 and compile that against the S310 headers. You wont be able to sign the firmware images, but its by far the path of least resistance. How to add Legacy DFU support to your S310 application is explained on this Infocenter page.
