Here's what I'm running:
MinimOSD w/ ArduCAMOSD_19_MAV10.hex
APM2 w/ 2.6
It _sort of_ works...in that it works fine, but in areas where there is NO overlay activity, there are garbage characters overlaid.
When I power up the OSD, at first I get a clear video feed, then as soon as OSD starts to boot, I see this garbage anywhere there isn't OSD generated overlay. Everything else works fine.
I've re-updated the firmware, and even tried dumping on the newest .mcm charset I could find, which made no difference. I'm NTSC but I've tried the settings for both w/ no difference.
I've searched around a bit and can't seem to find any posts about this occuring w/ other folks.
whohooo, finaly, I was able to get it work when I load new firmware and charset from the https://github.com/night-ghost/minimosd-extra.
Actually in the new firmware is not possible disable OSD by screen switching so I load my previous firmware (MinimOsd_Extra_Copter_R800.hex) and it works now great again...
