标题: 强烈请求发布一个默认打开 UART3 串口的 RK-3288刷机包！
本帖最后由 xmllmx 于 2016-4-28 11:10 编辑

反复修改编译刷机尝试，4.4 默认版、4.4pad版，5.1版，打补丁，修改dts，刷 kernel.img 和 resource.img。无一成功！

均不出现 /dev/ttyS3 !

翻遍了论坛中所有与此问题有关的帖子，虽然版主大人一再确认没有问题，但没有一个能解决问题。帖子中提问的朋友至今也没有一个人是反馈获得成功了的。

因此，强烈请求版主大人发布一个默认打开 UART3 串口的 RK-3288刷机包！以便我们刷机之后就可以使用 UART3 串口。

我们是购买了 rk-3288 的客户。

有没有办法，像Beaglebone Black那样，只需在用户层修改一下配置，就能实现引脚功能的动态配置呢？

唉，我这里也是这个问题，使用uart口实在是麻烦，我们在为之后正式产品选型，如果还是那么麻烦的话，之后只能不使用firefly的产品了

&uart_bb {

};

&uart_gps {
      status = "okay";
      dma-names = "!tx", "!rx";
      pinctrl-0 = <&uart3_xfer &uart3_cts>;
};

这样就能打开啊。我都试过是可以的

这个和硬件没关系把，你软件改好才有/dev/ttyS3出来，如果没有的话你要检查一下你的内核是否成功烧写进去。
可以看一下内核时间cat /proc/version ，是否和生成的内核时间一致。如果不一致有可能是boot.img里面带有以前的kernel，这就要重新烧写一个不带内核的boot.img

作者: syjh7370628 时间: 2016-5-16 01:41
楼主问题解决了吗？我也遇到同样的问题，原来烧写的默认版 Android SDK (firefly-rk3288_android4.4_git_20141211.tar.gz )按照wiki修改之后可以调用ttyS3，后来由于项目需要换了个pad版本的，修改后串口3就找不到了。。

作者: 牛头 时间: 2016-5-16 09:38
感谢你的建议，合理的建议我们会采纳的。

作者: xq98 时间: 2016-6-16 06:06
这个固件有了么？
我这里也弄不成，正如7楼所说的。实际上我怎么改kernel和resource烧到板子上，它根本就不执行新的。

我只用的是Firefly-RK3288_Android4.4_201602251453，在此基础上加改过的kernel和resource.不执行我改过的kernel和resource。还是老的。

这样要能改好才怪呢！

不知道哪里的问题。

作者: zxx686131 时间: 2016-7-27 17:19
你编译时候所使用的dts ，比如make xxxxx.img 那就是对应 xxxxx.dts里面去找
