【一起玩esp8266】板子收到，上电测试 [复制链接]

上周一直在出差，这周才拿到板子，今天上电试了一下，发现有问题，应该是固件刷的有问题。每次复位后显示的信息都不对，如下图：

然后是敲命令，有的命令可以，有的命令就不行。
比如
>>> import os
>>> os.listdir()
显示的就是乱的，如图

升级最新固件后还是一样的，固件检测是false：
>>> import esp
>>> esp.check_fw()
size: 527496
md5: 55bbc75678b4bbb269ecb3e59e821ebf
False

现在卡在这里了，还在继续研究………………

先擦除Flash，然后在刷固件就正常了。

用这种方法进行到安装pip的时候会报错，换了一台电脑也是一样的情况，如下：

看起来像是网络问题，下载不了需要的文件，重新运行试试，或者需要一个网络代理。

也可以安装最新版的python2，它已经带有pip了。
