avrdude or AVR studio, which is wrong?
I've got a JTAG-ICE mkII that avrdude can access with USB and AVR studio cannot. Reading previous threads on this subject hasn't resolved the issue for me. It seems to me that...

What could cause this "reset"?

USB vs JTAGICEmkII
USB programming don't like me yet again. I have no idea what changed. "My" computer is a Windows XP box set for automatic updates. I'd mostly been using a JTAGICEmkII to program a...

USBKey with two virtual serial ports
I have some thoroughly untested code that steals heavily from the USBtoSerial demo. For debugging purposes, it would be useful to have another virtual serial port attached to...

SCK between bytes
Between bytes, what is the state of SCK between bytes in SPI. From the atmega168 datasheet, it seems to be CPOL, but, so far as I can tell, it's not explicitly specified....

messages from build scripts
I used the scripts in build-avr-gcc-4.2.2-libc-1.6.2-makeinfo-fixed.tar.gz to build avr-gcc and avr-gdb . Everything seems to have gone well, but a couple messages are a bit...
