We made an Ethernet loopback cable (1-3, 2-6, 4-7 & 5-8) according to <How to wire a ethernet loop back adaptor or cable | Malcolm's Tech Tips>, and running Platform SDK v1.1.0 output/mx6dq/obds/smart_device_rev_c/obds.bin on i.MX6Q-SDP. We running Ethernet loopback fail as below, but same board can load uImage and mount nfs as rootfs via same Ethernet port. Is there anything we can check?
---- Running < RGMII AR8031 G-Ethernet Test >
Would you like to run the Ethernet loopback test?
(Please note that in order to run the test, you need to
first plug in a loopback cable to the Ethernet port.)
