gemini: sl3516: Mainlining of NS 2502
From: Corentin Labbe
Date: Mon Apr 05 2021 - 14:40:07 EST
Hello
I own an Edimax NS 2502, which is a NAS based on StormLinix 3516.
I successfully upgraded it with a recent Linux.
The DTB I use is the following:
/dts-v1/;
#include "gemini.dtsi"
#include <dt-bindings/input/input.h>
/ {
model = "Edimax NS-2502";
compatible = "edimax,ns-2502", "cortina,gemini";
#address-cells = <1>;
#size-cells = <1>;
memory@0 {
/* 128 MB */
device_type = "memory";
reg = <0x00000000 0x8000000>;
};
chosen {
bootargs = "console=ttyS0,19200n8";
stdout-path = &uart0;
};
mdio0: ethernet-phy {
compatible = "virtual,mdio-gpio";
gpios = <&gpio0 22 GPIO_ACTIVE_HIGH>, /* MDC */
<&gpio0 21 GPIO_ACTIVE_HIGH>; /* MDIO */
#address-cells = <1>;
#size-cells = <0>;
phy0: ethernet-phy@1 {
reg = <1>;
device_type = "ethernet-phy";
};
};
soc {
flash@30000000 {
status = "okay";
/* 8MB of flash */
reg = <0x30000000 0x00800000>;
partition@0 {
label = "RedBoot";
reg = <0x00000000 0x00020000>;
read-only;
};
partition@20000 {
label = "kernel";
reg = <0x00020000 0x00700000>;
};
partition@720000 {
label = "VCTL";
reg = <0x00720000 0x00020000>;
read-only;
};
partition@740000 {
label = "CurConf";
reg = <0x00740000 0x000a0000>;
read-only;
};
partition@7e0000 {
label = "FIS";
reg = <0x007e0000 0x00010000>;
read-only;
};
};
syscon: syscon@40000000 {
pinctrl {
/*
* gpio0agrp cover line 0-4
* gpio0bgrp cover line 5
*/
gpio0_default_pins: pinctrl-gpio0 {
mux {
function = "gpio0";
groups = "gpio0agrp",
"gpio0bgrp";
};
};
};
};
gpio0: gpio@4d000000 {
pinctrl-names = "default";
pinctrl-0 = <&gpio0_default_pins>;
};
ethernet@60000000 {
status = "okay";
ethernet-port@0 {
phy-mode = "rgmii";
phy-handle = <&phy0>;
};
ethernet-port@1 {
/* Not used in this platform */
};
};
usb@68000000 {
status = "okay";
};
usb@69000000 {
status = "okay";
};
};
};
This is a bit of copy paste of other DTB.
With it I boot successfully to a shell.
BUT neither ethernet nor USB works.
This is the bootlog:

Inserting an USB dongle give nothing.
As shown, udhcp cannot get an IP.
Setting one at hand does not fix anything, ping fail.
Can someone help me bring up at least ethernet ?
Thanks
