Firefly-RK3399J linux buildroot degug串口问题

Firefly-RK3399J编译出来 linux buildroot本后后，启动后uboot的degug串口有打印信息，但是进入kernel后串口就无打印信息了，只打印了内核一部分打印信息就停止了，HDMI界面一直打印。后来以为是dts禁止了，但是打开后还是不可以，烧录官方的固件是可以的，dts和系统log如下
dts代码

          };

已解决，
&uart2 {
      status = "disabled";
}
在设备上关闭uart本身串口功能后，debug口才可以用

在这个rk3399-linux.dtsi设备树文件中.

宇智波流浪 发表于 2020-11-26 16:53:30

大佬啊 已经成功解决，多谢！！！！

oopsmartin 发表于 2020-11-27 11:45:17

能请教一下，uboot怎么改将默认打印的串口从uart2改为uart1吗

chnchmhgw 发表于 2020-12-9 11:00:08

很赞，解决了我在firefly-rk3399-aiojd4开发板编译common-sdk版本编译的问题，多谢
