Firmware Update = "FAIL: lost synchronisation with the bootloader"

Playing with the 3DR modems I thought I'd get the firmware updated.  I got a few error messages though.

System is connected to the internet.  Both the ground and air radios give the same problem.  Trying 1.3->1.5 upgrade.  Mission Planner is updated using the auto update.

.

Is there a stand-alone firmware updater?  Tying the updater into Mission Planner and doing autoupdates is NOT a good method.  For a dev unit like this we really need more control and less ties to other potential problems.

Error log from Mission Planner console...

So I think I fixed things to the next step...

I downloaded the latest snapshot from sdcc.sourceforge.net

After extracting that I copied the "bin" directory from the archive to /usr/share/sdcc/bin/

.

But now I get another error when compiling...

--------------------------------------------------------------------

jake@PPZcomp:~/SiK/Firmware$ make all


% build bootloader for hm_trp
make[1]: Entering directory `/home/jake/SiK/Firmware'
AS bootloader/crtstart.asm
CC bootloader/bootloader.c

bootloader/flash.h:45: syntax error: token -> '__at' ; column 11
make[1]: *** [obj/hm_trp/bootloader.hm_trp/bootloader.rel] Error 1
make[1]: Leaving directory `/home/jake/SiK/Firmware'
make: *** [build.bootloader.hm_trp] Error

-----------------------------------------------------------

I just needed a little more time to fix the previous problem, but this error is kind of stumping me and I don't really know where to start on this.  Any help appreciated!

I don't know if you just updated the github readme or if I just noticed it, but thanks.  I see there's a few more things I may need.
