色々試行錯誤してようやくできたでまとめて置く。
Step1.ソフトのインストール
$ sudo apt-get install bison automake autoconf flex git gcc
$ sudo apt-get install gcc-avr binutils-avr avr-libc
$ wget http://download.savannah.gnu.org/releases/avrdude/avrdude-6.3.tar.gz
$ ./configure --prefix=/opt/avrdude --enable-linuxgpio
Step2.ソースの修正
なせかprintf("%ud",gpio) という部分で 数字d となって 文字列が正しく出ない問題があるので
linuxgpioのソース上にある %ud を全て %d に書き換える。
Step3. avrdude.confの修正
下図のようなピン配置にした場合、
まずソース内に入っているavrdude.confを開き、「linuxgpio」で検索して、以下の様に編集する。
------------------------------------------------------------
programmer
id = "linuxgpio";
desc = "Use the Linux sysfs interface to bitbang GPIO lines";
type = "linuxgpio";
reset = 12;
sck = 16;
mosi = 20;
miso = 21;
;
------------------------------------------------------------
avrマイコンを書き込む用のピンアサイン |
電源は3.3VとGNDを使う事。
(5Vでも良いが、RPI自身が3.3V/5Vトレラントでないので注意しておくと良い)

もしDigisparkを使う場合は最後の行に以下の内容も追記しておく。

Step4.ビルド&インストール
$ make
$ sudo make install
Step5.配線
Digispark ATTiny85の場合は、
D0―MOSI
D1―MISO
D2―SCK
D5―RESET
Digispark pro ATTiny167の場合は、
PA2―MISO
PA4―MOSI
PA5―SCK
PB7―RESET
接続する時の注意ですが、MISO/MOSIはクロス接続にすること。
ストレート接続すると、TX-TX、RX-TXみたいな具合になって通信できません。
Step6.動作確認結果
$ sudo avrdude -c linuxgpio -pt167
avrdude: AVR device initialized and ready to accept instructions

以上まとめでした。
