我看到有3128的dts文件，关于rk818部分，有以下的设置：
&rk818 {
gpios =,;
對你來說應該沒有影響,
估計是 RK3128 + DDR2 與 RK3128 + DDR3 的差異
^^^^^^^^^^^ ^^^^^^^^^^^
FirePrime FirePrimeS+ 你好，麻烦问一下，是否电源正常以后，3288芯片电路和USB-OTG电路焊接好，用那个烧写固件程序就应该能够识别的这个设备啊，我也是自己做的板子，3288+RK808B，现在想烧写U-boot，烧写固件工具识别不到设备什么原因呢？麻烦指导一下吧。 你好，请问下你的问题解决没有，你用RK818有没有遇到待机重启的问题呢？ 你好，请问下你的问题解决没有，你用RK818有没有遇到待机重启的问题呢？ rk818配置如下, 已验证可以解决无法开机的问题, 希望有帮助.

}; 请问楼主的问题解决了吗，我做了一个RK3368+RK818-1的 也是系统进入到RECVRY就不运行了，跟楼主的现象一致，跪求解决办法搞了几天了。 立豕殳 发表于 2018-12-14 18:45
