Please Guide to do manual configuration ifconfig eth0 down; ifconfig eth0 upnuc970-emac0 nuc970-emac0: eth0 is OPENED cat /proc/interrupts16: 16101 - nuc970-timer0 |

What board are you using? Is there any error message during system boot up?
Sincerely,

Any help or solution?? |

You didn't turn off LCD in U-Boot.
WARNING: LCD enabled in loader but not in kernel, this may cause EMAC hang...

Yes both are on already |
|
Any suggestion/help further? |
|
Please test attached kernel image. If the SW21/SW38 is ON and EMAC0 still doesn’t work, I would guess there’re something wrong about your board. |

While connecting through putty using IP i am getting this.... login as: root Welcome to Automation BOS System.. |

What city are you in? I can't tell what goes wrong from your description. Do you have other 972 board in hand that you can give it a try?

I am Vadodara(Baroda), Gujarat, India. No i don't have any other NUC970 board. |
|
One more thing i have noticed while i am building through buildroot toolchain in environment file it was not setting any variable for ethernet. My environment Variables are as follows. Will it affect.? baudrate=115200 |
|
No, the Uboot env setting is irrelevant with the EMAC issue in Linux kernel. |
|
Ok. Than I have to find something in kernel side only... Is there any other kernel configuration required for EMAC Any changes required in Config files.? But in my files it is like this. If try do changes and than make, its giving me error in make. |
|
The original source doesn't have the extra colon. And can be built without problem. |
|
Ok. I removed extra colon but nothing changed in previous one. Ok. Thank you again. If you get any solution idea pls let me know. I will search out the fault. |
|
Hey, I got a new NUC980DK61YC Evaluation board with me. I am trying to load image files and uboot files in SPI but it was showing this error. NUC980 IBR 20180813
