BootloadHID & ATmega324pa
Posted: Fri Nov 11, 2011 2:11 pm
Hi, I'm unable to get this combination working, any suggestions please?
I was able to run the HIDkeys example on the same hardware
bootloadHID.2010-07-29
Fuses BOOTSZ[0.1] = 00 set to 4kB bootloader by default, BOOTRST vector = 1 so the code should start in boot vector
In the makefile
In bootloader config I set that the loader starts up everytime
D+ pin is also connected to the INT0 pin DP2
in the Usbconfig.h I have set some defines to make sure the INT0 vector is set right
There's the same unanswered thread here http://forums.obdev.at/viewtopic.php?f=8&t=5708
I've also followed this thread where they says that I should compile code for non-P variants of chips, but there's no non-P variant for ATmega324

Any idea and suggestion very appreciated.
Thanks
