imx6 dm9000 no work，kernel is 3.14.28，linux system

[jianfeichang]

I'm  work dm9000 in imx6，CS0 is 08000000，interrupt is gpio4_io5   imx6qdl-sabresd.dtsi  is

+MX6QDL_PAD_GPIO_19__GPIO4_IO05  0x80000000

+

ethernet@18000040 {
compatible = "davicom,dm9000";
reg = <0x18000040 0x2 0x18000044 0x2>;
interrupt-parent = <&gpio4>;
interrupts = <5 2>;
local-mac-address = [00 00 de ad be ef];
davicom,no-eeprom;
};

make menuconfig add dm9000

Hi jianfei

log error "dm9000 8000040.ethernet: read wrong id 0x01010101"

may mean that dm9000 is not read correctly from i.MX6Q side, one can check

timings with oscilloscope and adjust them using imx6qdl-sabreauto.dtsi

example &weim { "weim-cs-timing " :

linux-2.6-imx.git - Freescale i.MX Linux Tree 

Best regards
igor

thank you！igorpadykov

  dm9000， Now, it can work！ EIM is OK 

&weim {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_weim_nor_1>;
#address-cells = <1>;
#size-cells = <1>;
status = "okay";

nor@0,0 { compatible = "cfi-flash";
reg = <0 0x02000000>;
//#address-cells = <1>;
//#size-cells = <1>;
bank-width = <2>;
fsl,weim-cs-timing = <0x00620081 0x00000001 0x1c022000 0x0000c000 0x1404a38e 0x00000000>; };
};

add dm9000

ethernet@0800040 {
compatible = "davicom,dm9000";
reg = <0x08000040 0x2 0x08000044 0x2>;
interrupt-parent = <&gpio4>;
pinctrl-0 = <&dm9000_gpio>;
interrupts = <5 4>;//4 表示 触发类型 2 低电平 1 高电平
local-mac-address = [00 00 de ad be ef];
// davicom,no-eeprom;
// wakeup-gpios = <&gpio4 5 2>; 0是低电平 唤醒
// gpio_int = <&gpio4 5 2>;
};
/*add dm9000 cjf*/
dm9000_gpio:dm9000{
fsl,pins = <
MX6QDL_PAD_GPIO_19__GPIO4_IO05 0x80000000
>;
};

OK！
