迅为的4412开发板怎么样？请实际使用过的同学给个建议吧

Posted 2023-04-12

到目前，只有讯为的4412开发板资料多，并且还有很多视频教程，本人觉得其实资料比开发板更重要，虽然友善之臂、友坚的也不错，但是它们并不适合初学者来学习，因为资料很少，买回来只能当个平板电脑使。所以要是想学习的话就选讯为的吧。 参考技术A 很棒的，技术有优势，资料很全，售后也给力 参考技术B 讯为 友善的 都用过，只能做学习板，都有很多问题。讯为的虽说有个电源管理芯片，还不如友善的dcdc处理的好，至少人家散热比你强。liunx的话，讯为自己都没好好测试。 参考技术C 讯为的iTop-4412板子，资料最多。datasheet也是开放的，注意！这个4412的datasheet有很多版本，你网上找到的可能是公版，讯为售后给你的是最新配套的版本。

总体上来讲，三星的2440的开发板资料最全，很适合新手。但如果考虑到性能强的4412，建议讯为。 参考技术D 初学者 不推荐用这款。肯定要用资料最全的

请教：用迅为4412开发板开机时卡在Android静止画面

我使用迅为的4412板子

 

发现开机的时候会有机会卡在Android静止画面
使用RS232接机器log后比较正常与无法开机进入的log
发现缺少执行了以下内容
因此想请教各为这段缺少的内容是执行什么样的函式呢
