A20 + Gigabit Eth KSZ9031 Loopback Test Procedure

[nikson]

Hi,

I have custom made board (a20+KSZ9031), everything works good, but when I interrupt booting and use U-boot commands to set ipaddr and net mask, and init local loopback on mii side, I get the following:


=> mii write 1 0 4140
=> mii write 1 9 1300
=> setenv ipaddr 192.168.0.25
=> setenv netmask 255.255.255.0
=> ping 192.168.0.25
ethernet@01c50000 Waiting for PHY auto negotiation to complete......... TIMEOUT !
Could not initialize PHY ethernet@01c50000
using musb-hdrc, OUT ep1out IN ep1in STATUS ep2in
MAC de:ad:be:ef:00:01
HOST MAC de:ad:be:ef:00:00
RNDIS ready
The remote end did not respond in time.ping failed; host 192.168.0.25 is not alive


Can someone provide the right loopback test procedure using U-boot commands, please?

BR, Nikola
