[Simulavr-devel] [PATCH 10/13] The beginnings of an AVR XML file to AVR

[Simulavr-devel] [PATCH 10/13] The beginnings of an AVR XML file to AVR device class converter |
|
Date: |
Tue, 3 Mar 2009 23:46:25 +0100 |
If one applies this patch, one needs to call avr-fab.py from
within the src/fab directory, with the Atmel .xml files in place.
For now, it will create only two, incomplete small AVR device classes,
for the tiny2313 and the tiny15l.
