Hi All,
I still have not found a solution and I am a bit desperate. I did not
seem to be able to send any packets (using ping) from the FECO on the
M5282Lite board to the tftp host, however pings from the host were
answered and I saw packets going from the coldfire board to the host
in wireshark. I also get a strange error when I ask for mii info:
uBOOT=>> mii device
MII devices: 'FEC0'
Current device: 'FEC0
uBOOT=>> mii info
MII not complete
MII not complete
...
a dump gives me:
uBOOT=>> mii dump
MII not complete
0. (ffff) -- PHY control register --
(8000:8000) 0.15 = 1 reset
(4000:4000) 0.14 = 1 loopback
(2040:2040) 0. 6,13 = b11 speed selection = ??? Mbps
(1000:1000) 0.12 = 1 A/N enable
(0800:0800) 0.11 = 1 power-down
(0400:0400) 0.10 = 1 isolate
(0200:0200) 0. 9 = 1 restart A/N
(0100:0100) 0. 8 = 1 duplex = full
(0080:0080) 0. 7 = 1 collision test enable
(003f:003f) 0. 5- 0 = 63 (reserved)
I have tried a few other commands, but am not sure how to interpret
the output. See below:
uBOOT=>> mii dump 0 1
MII not complete
1. (ffff) -- PHY status register --
(8000:8000) 1.15 = 1 100BASE-T4 able
(4000:4000) 1.14 = 1 100BASE-X full duplex able
(2000:2000) 1.13 = 1 100BASE-X half duplex able
(1000:1000) 1.12 = 1 10 Mbps full duplex able
(0800:0800) 1.11 = 1 10 Mbps half duplex able
(0400:0400) 1.10 = 1 100BASE-T2 full duplex able
(0200:0200) 1. 9 = 1 100BASE-T2 half duplex able
(0100:0100) 1. 8 = 1 extended status
(0080:0080) 1. 7 = 1 (reserved)
(0040:0040) 1. 6 = 1 MF preamble suppression
(0020:0020) 1. 5 = 1 A/N complete
(0010:0010) 1. 4 = 1 remote fault
(0008:0008) 1. 3 = 1 A/N able
(0004:0004) 1. 2 = 1 link status
(0002:0002) 1. 1 = 1 jabber detect
(0001:0001) 1. 0 = 1 extended capabilities
uBOOT=>> mii dump 0 2
MII not complete
2. (ffff) -- PHY ID 1 register --
(ffff:ffff) 2.15- 0 = 65535 OUI portion
uBOOT=>> mii dump 0 3
MII not complete
3. (ffff) -- PHY ID 2 register --
(fc00:fc00) 3.15-10 = 63 OUI portion
(03f0:03f0) 3. 9- 4 = 63 manufacturer part number
(000f:000f) 3. 3- 0 = 15 manufacturer rev. number
uBOOT=>> mii dump 0 4
MII not complete
4. (ffff) -- Autonegotiation advertisement register --
(8000:8000) 4.15 = 1 next page able
(4000:4000) 4.14 = 1 reserved
(2000:2000) 4.13 = 1 remote fault
(1000:1000) 4.12 = 1 reserved
(0800:0800) 4.11 = 1 asymmetric pause
(0400:0400) 4.10 = 1 pause enable
(0200:0200) 4. 9 = 1 100BASE-T4 able
(0100:0100) 4. 8 = 1 100BASE-TX full duplex able
(0080:0080) 4. 7 = 1 100BASE-TX able
(0040:0040) 4. 6 = 1 10BASE-T full duplex able
(0020:0020) 4. 5 = 1 10BASE-T able
(001f:001f) 4. 4- 0 = 31 selector = ???
I also tried to look at the tftp server side of things:
=>> sudo mii-tool -v eth1
eth1: negotiated 1000baseT-HD flow-control, link ok
product info: vendor 00:60:51, model 0 rev 1
basic mode: autonegotiation enabled
basic status: autonegotiation complete, link ok
capabilities: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
advertising: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
link partner: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
Any more advice on what could be wrong or how to debug it would be
greatly appreciated.
