Is it possible to flash bone80 onto Debian 8

Just got into infinite trouble - need to use industrial temp boards for production and I thought I could
flash the bone80 production image onto these machines, but no joy.
They use Linux beaglebone 4.4.68-ti-r110 #1 SMP Wed Jun 21 04:31:35 UTC 2017 armv7l GNU/Linux
and the flashing process doesn’t even start.
Is this a hardware incompatibility or software problem?

I cannot use the existing image because I have a need to allow users to dynamically change the ip address of a
machine depending on installation parameters and this is really difficult to script with connman, unlike the old network
manager. Replacing connman has not worked - some critical files are overwritten.

Yes, documented here

Regards,

So remove connman.

And use /etc/network/interfaces like you used to…
