Re: [avr-gcc-list] Does anyone know how to write avrdude configuration file effectively ?

Sorry, the documentation for this might really be outdated.

These are parameters from various sections of the Atmel XML part
description file, which are required in order to talk with Atmel tools
(STK500, STK600, AVRISPmkII, JTAG ICE mkII, AVR Dragon).

Some of them map to the datasheet (like the "delay" parameter here),
most others are internal to the STK500v2 (in this case) firmware.

Unfortunately, there's currently no one-stop method to generate these
from the XML file.  Some of the parameter blocks (like the debugWire
parameters or the high-voltage programming ones) can be generated with
xslt, using .xsl "style sheets" from the tools/ subdirectory, others
(like STK500v2 ISP parameters) are unfortunately still created by
copy&pasting an existing entry, and then manually verify against the
XML file section.
