I got 2 MXK PDB with OSD from Banggood, and one works perfectly, but I am not able to flash MWOSD on the second one. I get this error message in the Arduino IDE:

I get the same error when trying to flash my beerotor OSD with a FTDI adapter. The Beerotor OSD works fine, but I am not able to configure ut from my computer.
I have tried with MWOSD 1.5, 1.6 and ScarabOSD 1.5, 1.6 (shouldn't make any difference when flashing with arduino IDE).

I also got the same problem when trying to flash my Openlog SD card writer with the Blackbox software

I personally haven't experienced this.. but a quick google suggested the causes of this error might be:

1. Bootloader is either missing or corrupted. This is fairly unlikely.
2. Wire connected to pin 0 (RX)
3. Wrong COM port is chosen within the arduino IDE.
4. Drivers are not installed. You can update it within the Device Manager if you are using Windows

For fixes take a look at this:

Worse case scenario is report to BG and send them screenshots of your error, they might replace it for you.

I'll have to try that.  I have a few with that problem,  I just assumed it was toast.  I find minimum OSD is  little finicky

Didn't see any mention of Arduino version. I've heard that newer versions can be finicky with mwosd and it's best to use the earliest release (Arduino that is). I only mention it cause I couldn't flash my minimosd till I had tried that. Sorry if this is irrelevant.

I had that avrdude error on my last micro. I configured a few in the past so everything is fine with my config, I also thought that one is dead. What helped is I plugged it to FTDI right before arduino started uploading.

I'm using Arduino 1.6.7 on a mac. It is not the latest, but I can try to go back to an earlier version

I went back to 1.0.5 or 1.0.6, can't check right now.
