Hello Sir,
I am using imx6dl custom board and linux 4.9 based android nougat binary, but i am not getting ip address and not able to ping.
Could you please help me on this regarding Ethernet issue.
Below is the screen shot of circuit design:
Processor side:
PHY side:
Below is the log of Ethernet ping test:

Hi Ramesha
lan8720 is supported on i.MX6SL EVK
imx6sl-evk.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel
First one can check rmii clock in uboot setup_fec()
mx6sabresd.c\mx6sabresd\freescale\board - uboot-imx - i.MX U-Boot
and check if rmii works fine in uboot.
Best regards
igor

Hi Igor,
Thanks for the reply,
i have measured clock signal and voltage measurement getting expected voltage and clock.
Please suggest me if you want me to test/measure other way to check hardware side of Ethernet side.
Thanks & Regards,

Hi Ramesha
regarding hardware one can look at Chapter 10 Using the RMII Interface i.MX6 System
Development User’s Guide
https://www.nxp.com/docs/en/user-guide/IMX6DQ6SDLHDG.pdf

Thanks for the quick reply Igor,
I have observed Chapter 10 using Chapter 10 Using the RMII Interface i.MX6 System
Development User’s Guide. looks our schematic is matching as per user's Guide.
i would like know about what should be the length of Enet_clk distance, in our design Enet clk distance is 136.206mm is that correct?
Thanks & Regards,
