Ok, the usual #pragma stuff doesn't work but the __attribute__((packed)) works like a charm.

And yes I am working on an onboard OSD (see messages "Protocol for the downlink").

For now I am using a design with a max7456 chip that only allows text. I can already print usual data like speed, altitude, climb rate, etc.

My next goal is to make a graphical OSD with the usual artificial horizon. I think I will be able to publish this next version. The actual version is a mix of open source and not open source stuff and I can't publish it.

You're working on a OSD?

Well, after some research it seems that gcc doesn't like #pragma options but might work with the __attribute__ ((packed)) trick…

I'll have a look tonight…
