Hi everybody, I am new to all this and need some help. I got a APM 2.8 and wanted to flash firmware APM copter 3.5.5. Quad. No matter what version or computer I am using, I am always getting
Upload succeeded but verify failed: exp D3 got C3 at 146
What I have done so far:
MP 2.0.24 on Ubuntu 16.04 runs great but the error above mentioned
MP 1.3.53 on Ubuntu 16.04 running with mono runs great same error
MP 1.3.55 on Windows 7 (Virtual Machine) runs great same error
At the very first beginning I added sbus support by flashing which worked fine.
Also tried to flash other firmware e.g. plane, does not work either. Now I am stuck! Does anybody have any idea what could be wrong? Thanks for some help
Its been a while since I’ve played around with ArduCopter / Pixhawk / APM, but I thought APM could only update to 3.2.1 max (I think partly due to size) and hardware capability. If you do a search on latest firmware APM 2.8 can update to you’ll find a few references to this. Good Luck!
nvpowerdoc was right. APM 2.8 does not support the latest arducopter versions. Copter 3.2.1 is the latest firmware supported by the 2 series boards (due to the massive size of the code)
You can either use Mission Planner (download it from the ArduPilot Website) - it will find the latest firmware available for the 2.8 board
or go to http://ardupilot.org/copter/docs/common-downloads_firmware.html - where you will find anything to know
Thanks for the tips, but MP detects automaticly that the board is outdated and downloads the latest firmware for the APM 2.8. But I also tried to download it manually and install it via custom. Same error!
