Firmware Updates

[travisgoodspeed]

Firmware updates come in an encrypted form, but they are decrypted by the radio during the loading process. md380-dfu should be able to send the encrypted update, letting the radio take care of the decryption.

Close this issue when the md380dfu can flash firmware

I may have something for this, but I learned everything I know about USB, DFU, and a fair amount of python in getting it to work, so I have little confidence my code is worth opening a pull request for. I also made lots of changes in working to understand everything.

But, it does work! (on my machine and radio).
I also have PCAPs of the original upgrade.exe pushing new firmware to the radio I can share on request.

Thanks @mach327, I confirm that your fork works to reflash the radio. I've been using the DFU bootloader for development, but this will conveniently remove that as a requirement.

Re-assigning this issue to myself for merging, which should be finished tonight or tomorrow.
