@edmcnierney With just days remaining for submission, and having extended the dates already for imaging issues and assistance, it is important to finalize and declare any and all the issues related to bootloader, images etc.
It is very likely that most of us would have considered Marshmallow as android base and developed and tested applications, images based on that, since at the time of tablet distribution, nougat was not available. Any deviation from that at this late juncture might have a cascading effect since the whole build/flash/test process is time consuming and cumbersome. And it is important to perform sanity on any change encountered, be at bootloader or android base level.
XPRIZE has clarified that all the tablets would be upgraded to Nougat if filesystem images are not submitted. If we are free to submit android stock filesystem images( for teams who have considered Android M as the base during development), we should also be allowed to submit stock bootloader images like some of the teams have pointed out. This would prevent any unintended and unknown consequence the bootloader might have for compatibility between Android M and N.
Overall, we are seeking the below clarification from XPRIZE:
- Are we allowed to submit android stock filesystem images for Android M ( system, vendor, boot, recovery ) ? and our userdata.img (of, course)
- Are we allowed to submit android stock bootloader image so as to prevent any unknown compatibility consequence?
- If we are not allowed to submit android stock bootloader, what would happen to a team who have submitted filesystem images for Android M, and during testing at XPRIZE, any boot issues creep in because the tablet would have bootloader for Android N?
We are seeking the above clarifications ASAP because with just days to go, we might not be able to perform full sanity on any submission changes encountered henceforth.
Also, if a poll is conducted within the teams for the choice of android base version, what would happen to a team who have developed and tested images based on a version which is different from the poll results? With just days to go, it may not be possible for any team to include changes and perform sanity completely. Such things should have been considered and published with enough time before submission.
