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
chosen {
                bootargs = "earlycon=uart8250,mmio32,0xff1a0000 swiotlb=1  ro root=PARTLABEL=rootfs rootfstype=ext4 rootwait overlayroot=device:dev=PARTLABEL=userdata,fstype=ext4,mkfs=1 coherent_pool=1m systemd.gpt_auto=0 cgroup_enable=memory swapaccount=1";
          };

fiq_debugger: fiq-debugger {
                //status = "disabled";
                compatible = "rockchip,fiq-debugger";
                rockchip,serial-id = <2>;
                rockchip,signal-irq = <182>;
                rockchip,wake-irq = <0>;
                rockchip,irq-mode-enable = <1>;  /* If enable uart uses irq instead of fiq */
                rockchip,baudrate = <1500000>;  /* Only 115200 and 1500000 */
                pinctrl-names = "default";
                pinctrl-0 = <&uart2c_xfer>;
                status = "okay";
        };

&uart2 {
        status = "okay";
};

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
