环境
APM2 MacOS10.9 使用brew安装avrdude
avrdude用法整理
常用参数
- -C 使用配置文件，举例例如
-C/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/etc/avrdude.conf这个conf是在网上下载的avrdude中包含的。 - -v verbose模式没什么可说的
- -c 指定烧写器型号，例如usbtiny
- -e 擦除rom，注意也会擦掉bootloader
-U 执行命令，包括烧录、设定fuse、执行指令等等。
具体说一下fuse参数 -U memtype:op:filename[:format]- -Uefuse:w:0xFD:m 设定extend fuse
- -Uhfuse:w:0xD8:m 设定fuse high位置
- -Ulfuse:w:0xFF:m 设定fuse low位置
- -Ulock:w:0x3F:m 解锁bootloader区域
- -Ulock:w:0x0f:m 锁bootlodaer区域
- -Uflash:w:~/stk500boot_v2_mega2560.hex:i 烧rom

以下是整理好的命令
第一步解锁bootloader area，第二步设定熔丝位
