I know there is a lot of discussion on this, and I've searched. I am able to program bootloaders with no issues using Windows 7, IDE 1.0.5 (AVRDude 5.11), and Olimex AVRISP MKII. I want to start using MightyCore, which requires 1.6.5+. I've tried several later releases with the version of AVRDude included with that release, and also with 5.11, without success. AVRDude 5.11 gives a syntax error, and later versions give "avrdude : stk500v2_recv_mk2 : error in USB receive", errors.If you know of some combination of the IDE equal to or greater than 1.6.5, and an AVRDude version that will work with it, please let me know. Thanks in advance.
The Olimex AVRISP MKII is trying to look like an MKII using LUFA. Looks like a patch is waiting to be accepted into avrdude. https://savannah.nongnu.org/bugs/index.php?40831The bug report tells what is wrong, so it must have been introduced between avrdude 5.11 and 6.0. At any rate, it does not look like a fix will happen soon. @Chuck is that an Atmel MKII or an Olimex MKII, looking at the bug it sounds like the Atmel one may work (although I could imagine it having timing issues).I have a Dragon ISP, but don't use it because the USB connector is so flimsy. I have been using the Arduino ISP sketch which is an example in the new IDE (1.6.7+).
