Bought a new printed circuit board for the Maxi (courtesy eletoponline365), reassembled Maxi cam w/new board, bench tested from USB and from 12v thru identical buck converter used on bike, all good, installed to bike and tested some more. Key only, key on-delay-start engine-key off, key on quick start, all good. Took bike out for test ride, stopped a few times (off/on), cam never missed a beat.
Problem solved, right? No.
A few days (and a few rains) later, went for a ride and exact same problem: First 3min. clips corrupt (3 of 'em), then recording perfectly until stop/start. 1st clip corrupt, others fine. Stop/start, 1st clip corrupt, others fine.
Since I got no response to any of this, I have to assume I'm the only one here on DCT having this problem with the new Mobius Maxi. When new PCB worked perfectly, assumed the USB port was at fault, but that's not the case. Cam is getting power properly, LEDs act as they should, and it is recording. Best guess is that corruption is caused by missing end-of-file (EOF) marker, thus corruption.
If anybody has any suggestions, I'm all ears (as Ross Perot once said).
