eth0 link is not ready

[jasonhsu]

Hi all,

I meet a problem. In my customer board, referenced from sabreauto-ai board, the eth0 link is not ready. could some one give me some advice? I really confused for some days. the log is as below:

====log below======

root@sabreauto_6q:/ # eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=1:01, irq=-1)

ADDRCONF(NETDEV_UP): eth0: link is not ready

====log end========

when I input "busybox ifconfig", it print log as below:

root@sabreauto_6q:/ # busybox ifconfig                                        

eth0      Link encap:Ethernet  HWaddr 1E:ED:19:27:1A:B3

it seems that no ip address is obtained.

However, If I use FSL official Sabreauto-AI referenced board with the same internet wire, it is ok and the board can access internet normally. log is as below:

root@sabreauto_6q:/ # eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=1:01, irq=-1)

compared with official referened board, my customer board cannot print the log in red. we have not changed ethnet module, it follows offcial referenced board. could you give some advices please? Any advices are appreciated.. thx a lot.

[igorpadykov]

Hi jianhua

you can check if new board has valid mac, setting

Uboot kernel boot parameter

fec_mac=xx:xx:xx:xx:xx:xx

Best regards

[jasonhsu]

Hi, igor

thx a lot for your reply.

After reading your information, I pay attention to the uboot log. The referenced board which connected to internet well can get right MAC addr, log is as below:

MMC:  FSL_USDHC: 0,FSL_USDHC: 1,FSL_USDHC: 2,FSL_USDHC: 3

In:    serial

Out:  serial

Err:  serial

Net:  got MAC address from IIM: 00:04:9f:03:0c:c9

FEC0 [PRIME]

Hit any key to stop autoboot:  0

MX6Q SABREAUTO U-Boot >

However, my customer board seems cannot obtain such addr, log is as below:

MMC:   FSL_USDHC: 0,FSL_USDHC: 1,FSL_USDHC: 2,FSL_USDHC: 3

*** Warning - bad CRC or MMC, using default environment

In:    serial

Out:   serial

Err:   serial

boot from emmc2

Net:   got MAC address from IIM: 00:00:00:00:00:00

FEC0 [PRIME]

Hit any key to stop autoboot:  0

========

Maybe this is the cause. I just guess ^_^. I think i must check this difference firstly.

and I also input "printenv" in the referenced board and customer board:

================

it seems the enviaroment is same.

igor, could you teach me : does the mac addr need to set manually or obtained automatically by systmem ?

[igorpadykov]

Hi jianhua

just for test you can set for new board mac address

the same as in reference board, setting

Uboot kernel boot parameter

fec_mac=xx:xx:xx:xx:xx:xx

For production boards one needs to purchase MAC addresses from

link below

http://standards.ieee.org/develop/regauth/grpmac/

Note, Freescale does not provide new mac addresses.

Best regards

Hi, igor,

thx for your reply.

I set fec_addr in uboot like below:

after savenv and reboot, the macaddr is still 00:00:00:00:00:00 in uboot, and still cannot connected to internet. there are no ipaddr with using "busybox ifconfig" after anroid booted up.

Is the seting way right or not?

[igorpadykov]

Hi jianhua

you rebooted so settings were lost.

For permanent settings you can look at example below:

program_mac_address.c

i.MX 6Series Platform SDK

for linux boot one needs to use

Uboot kernel boot parameter, refer to attached file

Table 6. Kernel Boot Parameters  p.9

~igor

[jasonhsu]

Hi igor,

thx for your reply.

I use android 4.3 OS, but i think u-boot and kernel might be same as linux as what you attached. I set fec_mac according to the document and what you said. however, the mac address is still not correct after execute "busybox ifconfig". It's really strange symptom.:smileyconfused:

Anyway, I'm very appreciated with you:smileyhappy:. I think I should check more and more :smileyshocked:

[igorpadykov]

Hi jianhua

I think it should work with below

IMX6_JB43_110_ANDROID_SOURCE_BSP : i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite, i.MX 6Solo

and i.MX 6Sololite Android jb4.3_1.1.0 0 BSP, Documentation and Source Code for BSP and Codecs..

~igor

[jasonhsu]

Hi, igor

yes, i just use this sdk. other modules work well. but ethnet is NG.:smileyconfused:

[igorpadykov]

Hi jianhua

MAC can be blown to fuses, please check

Table 5-10. Fusemap Descriptions IMX6DQRM

procedure given below

Q&A: How to program i.MX6 eFUSE?

~igor

[jasonhsu]

Hi, igor

I just try to do efuse for mac addr according to your way. it show below log:

MX6Q SABREAUTO U-Boot > imxotp blow --force 62 039f0400

ERROR: otp_wait_busy timeout. 0x262

ERROR: read failed

MX6Q SABREAUTO U-Boot > imxotp read 62              

Reading fuse at index: 0x62

ERROR: otp_wait_busy timeout. 0x262

ERROR: read failed

Both writing and reading is failed.  Why such operation is failed ?:smileyconfused:

efuse index of mac is 0x62 and 0x63

[jasonhsu]

Hi, igor,

I have burn mac address to efuse with blew way after android boot up:

echo 0x9f00ead3 > /sys/fsl_otp/HW_OCOTP_MAC0

echo 0x0004 > /sys/fsl_otp/HW_OCOTP_MAC0

uboot and kernel can get the correct mac addre now:

===========uboot log=======

boot from emmc2

Net:   got MAC address from IIM: 00:04:9f:00:ea:d3

FEC0 [PRIME]

Hit any key to stop autoboot:  0

=======busybox ifconfig log=====

          collisions:0 txqueuelen:1000

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

However, there is still no ip address obtained? Igor, do you have any advices?

[igorpadykov]

Hi jianhua

you can try "ip" kernel boot parameter, described

in attached in previous answer i.MX_6Dual6Quad_SABRE-SD_Linux_Release_Notes.pdf

Table 6. Kernel Boot Parameters

ip=none

ip = dhcp

ip=static_ip_address

~igor

[jasonhsu]

Hi, igor

I have tried to set ip = non or ip = 192.168.2.199, there seems no effect and no ip address obtained after android booted up.

and I have also tried to set ip like this way:

busybox ifconfig eth0 192.168.2.199 netmask 255.255.255.0

and it show log as below :

root@sabreauto_6q:/ # busybox ifconfig                                        

eth0      Link encap:Ethernet  HWaddr 00:04:9F:00:EA:D3 

          inet addr:192.168.2.199  Bcast:192.168.2.255  Mask:255.255.255.0

          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:1000

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

but no "inet6 addr: fe80::204:9fff:fe03:cc9/64 Scope:Link" displayed as FSL referenced board.:smileyconfused:

[igorpadykov]

Hi jianhua

you can try ping test from SDK i.MX 6Series Platform SDK : Bare-metal SDK

~igor

[jasonhsu]

Hi, igor

this problem had been solved. firstly, the mac address should be set. secondly, the AR8301 is virtual circuit. after re-welding, it is ok now.

thx for your help.:smileylaugh:
