RV1126 sdk v2.2.0 ethernet doesn't work on A201

RV1126

Hello,

The “new” rv1126_rv1109_v2.2.0_20210825 sdk doesn’t work fully with A201 board.
1) the rv1126-aybering.dts file is missing. This can be fixed by copying rv1126-aybering.dts and BoardConfig-aybering.dts to the right locations. However, the aybering “gmac” node does not compile.
Therefore, the ethernet port on A201 board doesn’t work.

The compilation errors are:

Reference to non-existing node or label “rgmiim1_pins” and
Reference to non-existing node or label “clck_out“ethernetm1_pins”

By using the “gmac”node from the rv1126-38x38-emmc.dts” file the repository compiles (and the camera for example works,tested) but ethernet obviosly doesn’t.

看下1.8 版本的 dts和 2.2的区别. 先不要直接copy

I managed to solve the issue using the following “gmac” node:

&gmac {
phy-mode = “rgmii”;
clock_in_out = “input”;

snps,reset-gpio = <&gpio3 RK_PA0 GPIO_ACTIVE_LOW>;
snps,reset-active-low;
/ Reset time is 20ms, 100ms for rtl8211f /
snps,reset-delays-us = undefined

assigned-clocks = <&cru CLK_GMAC_SRC>, <&cru CLK_GMAC_TX_RX>, <&cru CLK_GMAC_ETHERNET_OUT>;
assigned-clock-parents = <&cru CLK_GMAC_SRC_M1>, <&cru RGMII_MODE_CLK>;
assigned-clock-rates = <125000000>, <0>, undefined

pinctrl-names = “default”;
/ This one is the original what was in the new sdk /
/ pinctrl-0 = <&rmiim0_miim &rgmiim0_rxer &rmiim0_bus2 &rgmiim0_mclkinout>;/
/ This one is from the old rv1126-aybering.dts/
/ pinctrl-0 = <&rgmiim1_pins &clk_out_ethernetm1_pins>; /
/ This one is from rv1126-evb-v10.dtsi/
pinctrl-0 = <&rgmiim1_miim &rgmiim1_bus2 &rgmiim1_bus4 &clkm1_out_ethernet>;

tx_delay = <0x2a>;
rx_delay = undefined

phy-handle = <&phy>;
status = “okay”;
};
