Using bootargs to pass the serial settings has been deprecated for a
while. Please use stdout-path instead.
I tried following patch with my SR400ac (I put Archer C5 aside for now).
Hi Rafael
Take a look at for example the bcm911360k.dts
aliases {
serial0 = &uart3;
};
chosen {
stdout-path = "serial0:115200n8";
};
You need an alias to the serial device you want to us, and you should
list the speed, parity, bits etc.
That was actually my first try (just with s/uart3/uart0) and I got the same problem.
Hi Rafael
Try decompiling the generate .dtb file back to a dts and see if it
looks correct.
I decompiled dtb, it looks OK to me, let me paste relevant part:
chosen {
stdout-path = "serial0:115200n8";
bootargs = "earlycon";
};
aliases {
serial0 = "/chipcommonA/serial@0300";
};
memory {
device_type = "memory";
reg = <0x0 0x8000000 0x88000000 0x8000000>;
};
chipcommonA {
compatible = "simple-bus";
ranges = <0x0 0x18000000 0x1000>;
#address-cells = <0x1>;
#size-cells = <0x1>;
serial@0300 {
compatible = "ns16550";
reg = <0x300 0x100>;
interrupts = <0x0 0x55 0x4>;
clocks = <0x2>;
status = "okay";
};
serial@0400 {
compatible = "ns16550";
reg = <0x400 0x100>;
interrupts = <0x0 0x55 0x4>;
clocks = <0x2>;
status = "disabled";
};
};
I got some warnings, but I don't think they are critical:
Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name
Warning (unit_address_vs_reg): Node /chipcommonA has a reg or ranges property, but no unit name
Warning (unit_address_vs_reg): Node /mpcore has a reg or ranges property, but no unit name
