楼主
我修改了此处波特率为115200
fiq_debugger: fiq-debugger {
compatible = "rockchip,fiq-debugger";
rockchip,serial-id = <2>;
rockchip,wake-irq = <0>;
rockchip,irq-mode-enable = <0>;
rockchip,baudrate = <115200>; /* Only 115200 and 1500000 */
interrupts = <GIC_SPI 116 IRQ_TYPE_LEVEL_HIGH>;
status = "disabled";
};
内核启动执行到:
