maybe the problem i described is not clear, i have already pluggled the cable into my board. the detail operations list as below:
1.plugged the cable into my embeded board, and another port connect to my computer(win10).
2.power on the board without starting the network service in the bulid configeration file. etc,
3. the led of the net port in board and computer is on and blinking, at this time the phy is not init because i do not start the service.
4. when i input io-pkt-v6-hc -d mx6x in the command line, the led is off, and the link becomes down, the nicinfo and ifconfig info in the last email
the key point of this problem is why the status of ifconfig info is always no carrier, not active. Have you ever encountered such problems before?
another question is the Current Operation Rate of nicinfo is always unknown, what does this means ? which register is this read?

主题: Re: [atheros] status is always no carrier
Are you using a crossover cable to connect to your win10 machine? Have you tried plugging the cable into a switch?

hello,drivers-networking engineer:
My Development Environment
Host: Ubuntu 14. Qnx: SDP 7.0 Target: iMx6q Sabre Auto/AI
I face a strange problem when i am debugging phy(atheros ar8095) driver on imx6q board, when i have started the io-pkt service and configed ip, the nicinfo changes below:
--> nicinfo
fec0:
i.MX6 Ethernet Controller
Link is DOWN
Physical Node ID ........................... 000012 345678
Current Physical Node ID ................... 000012 345678
Current Operation Rate ..................... Unknown
Active Interface Type ...................... MII
Active PHY address ....................... 0
Maximum Transmittable data Unit ............ 1500
Maximum Receivable data Unit ............... 1500
Hardware Interrupt ......................... 0x96
Hardware Interrupt ......................... 0x97
Memory Aperture ............................ 0x2188000 - 0x2188fff
Memory Aperture ............................ 0x2098000 - 0x2098fff
Promiscuous Mode ........................... Off
Multicast Support .......................... Enabled
and the network port status is :
-->ifconfig
fec0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
address: 00:00:12:34:56:78
media: Ethernet 10baseT full-duplex (none)
status: no carrier
inet 192.168.1.11 netmask 0xffffff00 broadcast 192.168.1.255
inet6 fe80::200:12ff:fe34:5678%fec0 prefixlen 64 scopeid 0x11
whatever the configuration of the phy has made,the fec0's status is always no carrier. by the way, cable is connected to my win10 computer.
do you have any suggestions to my problem? thank u!
