I generated blink led .bin file on Linux and FreeBSD. I can flash any o= f them from FreeBSD using bossac, and Linux .bin file works, FreeBSD one do= esn't (the led is always lit). I checked the commands Arduino IDE is using = on Linux and FreeBSD, and they are the same. I tried this with arm-none-eab= i-gcc versions 4.9, 5.3 and 6.2. As all those versions are failing, maybe i= t's not GCC but binutils or something like that (just a wild guess). I woul= d be really grateful if someone could tell me how to pinpoint the error eve= n more.

I was able to successfully program my Due's with FreeBSD-compiled projects a couple of times -- generally simple ones that just connected and tested the serial plotter/monitor. However, we do differ from upstream a bit in that upstream seems to be sticking to arm-none-eabi-gcc 4.8.3 -- I kind of wonder if we're missing some flags in compilation/linking, but that wouldn't really explain why my simple tests worked out. =3D(
