Yes, the Trident will be running the same cockpit software. There will be changes in configuration and capabilities, since the hardware has changed a bit (handled with a platform abstraction layer in the code), but the code powering the logic and functions is the same. We have the intention of keeping it that way as well.
So far, I did an initial port in a very manual manner, taking a base DietPi image and manually customizing and installing all of the software/dependencies and writing modified scripts for firmware build/upload and whatnot. I’m currently working on the platform abstraction layer and reworking how we handle functions like building and uploading firmware, communicate with the MCU, etc. such that there is a standard path for getting the OpenROV software running on any computer module (will make it much easier for people to extend on and make images for other boards besides the Pi).
The initial go at this infrastructure should be ready for consumption soon. I’ll be sure to let people know when there is a relevant set of dev images available.
