第一次上电

灰小子

拿到板子快一周了，今天才第一次上电。
为啥呢，主要是在折腾串口工具。EVB-335X-II工控评估板竟然没提供ttl接口。郁闷的要死。
去年双十一更换了电脑，现在电脑不但没有并口接口了，串口也没有了。于是找到原来学习51单片机时的usb转串口工具，找到后，就是各种安装驱动程序阿，折腾了两天，在我的64位win7上也没安装成功。 最终决定放弃。今天得空，直接从核心板上飞线出来串口0的ttl。
于是开始了上电折腾。

天涯浪子123

看来你应该买一条usb转232的线啊！

为么上传不了图片，插入代码也不行。。。

你确定上电前都连接正确吗，我的经验是先找个相似的例子参考下

正确的。板载的linux正常启动了
