Remotely updating firmware
« on: August 02, 2019, 05:58:04 PM »
I have a project that will put BRX-based devices out in the field where I'm not going to be able to physically reach them. I've got a process that updates the program code remotely but I'm concerned that I'm going to get locked in to whatever firmware version the system ships with.

1. What are the restrictions about loading programs across different firmware versions? I'm guessing this is a no-no?
2. Is there any kind of mechanism to allow firmware to be updated remotely? I have no VPN access to these devices but they'll all have an SDCard and I can command them to do stuff remotely.

Newer firmware is fine. Downgrading is potentially bad. If you target a local development system with the oldest firmware you have in the field, DmD will prevent you from using features unsupported by that version.

There is currently no SDCard mechanism for firmware update.
