Building the old (insecure Bootloader) under SDK 12

[Roger Clark]

Can someone tell me the best way to build the old bootloader under SDK 12.

Looking in the examples, in SDK12, there is now only the bootloader_secure example

SDK 11 has the old version, but I'm not sure if I can use it with SDK12

BTW. I will try to get compile the secure version, but as I'm only in early testing, I'm not really to concerned about secure DFU and don't want to waste time on it if its possible to go back to the old insecure version

I don't see any problem building the old bootloader in SDK v12. You just need to copy all the files missing on SDK v12 from SDK v11.

If you use the same Softdevice, then the bootloader compiled on SDK v11 should also work with application compiled on SDK v12.

Note that the secure bootloader from SDK v12 is not backward compatible with the legacy bootloader. For future proof, i would suggest you to use the new bootloader instead of the old one.

Thanks

I have started building the secure bootloader, and I will persevere with it for a while, but its good to know, I can go back to the old version if necessary
