iMX6UL-EVK Ethernet Error in uboot

[fresxc]

Hi, all

I want to use PING in uboot, but there is a problem , and here is the output of uboot:

Here is my configurations:

#define CONFIG_FEC_MXC_PHYADDR 0x1 /* need board rework */

I do not know what to look for to resolve this problem...

Thank you in advance for your help !

Hi Fresxc

after setting #define CONFIG_FEC_ENET_DEV 0, no additional

code modifications are needed. Another port will not be available.

Please rebuild it and check ethernet following sect.4.4.1.1 Downloading

an image to MMC/SD attached Linux Guide for configuring the U-Boot

environment for network communications.

Best regards
igor
