Yikes Invalid device signature.Double check connections and try again, or use -F to over

为什么要烧bootloader

自己DIY的arduino nano板子,是无法直接用UART进行程序烧录的,需要先用ICSP给板子烧录bootloader。
其流程为:
Yikes Invalid device signature.Double check connections and try again, or use -F to over_第1张图片

但是烧录bootloader时报错如下

Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check.

然后点击 文件->首选项->显示详细输出->编译查看详细报错如下

Arduino:1.6.5 (Windows 8.1), 板:"Arduino Nano, ATmega328"

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x15

avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x15



avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x14



avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x01

上传出错。查看页面 http://www.arduino.cc/en/Guide/Troubleshooting#upload 获取建议。

avrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0x10

avrdude: initialization failed, rc=-1

         Double check connections and try again, or use -F to override

         this check.



avrdude: stk500_disable(): unknown response=0x12

各种调试都没找出错误,是芯片烧坏了

给一块现成的arduino nano烧录没有问题,但是给自己的arduino nano烧录会报错,而且电路也检查了没有问题,那么就是芯片烧坏了。

然后发现是芯片焊接时吹太久烧坏了,背面都起泡了。
换个新的芯片,先把锡膏烧融,然后快速贴上去芯片,再烧录bootloader就好了。
