LSDK: Q on how to make eno0 works on LSDK19.09

[mharada]

- Environment
  - Hardware
    - LS1028ARDB
  - SW
    - LSDK 19.09
  - eno0 is connected to the Host PC

- Description

  Hello expert. I'm just new to Layerscape SDK.

  After installing the after installing LSDK19.09 using flex-installer,
  eno0 can not work at all..
  I can not just make eno0 interface working on the environment above.
  Would you please someone please teach me how to enable it ?

- How to duplicate the problem.
  1. install pure LSDK19.09 using PC
  $ flex-installer -i auto -m ls1028ardb -d /dev/sdb
  2. Boot with the SD card
  3. enable eno0 interface
  $ ifconfig eno0 192.168.99.98 up
  4. send ping from the PC
  $ ifconfig eno0
  eno0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
  inet 192.168.99.98 netmask 255.255.255.0 broadcast 192.168.99.255
  ether f2:e7:70:50:93:18 txqueuelen 1000 (Ethernet)

  RX errors 0 dropped 0 overruns 0 frame 0
  TX packets 0 bytes 0 (0.0 B)
  TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

  $ ethtool eno0
  Settings for eno0:
  Supported ports: [ TP MII ]
  Supported link modes: 10baseT/Half 10baseT/Full
  100baseT/Half 100baseT/Full
  1000baseT/Full
  Supported pause frame use: Symmetric Receive-only
  Supports auto-negotiation: Yes
  Supported FEC modes: Not reported
  Advertised link modes: 10baseT/Half 10baseT/Full
  100baseT/Half 100baseT/Full
  1000baseT/Full
  Advertised pause frame use: No
  Advertised auto-negotiation: Yes
  Advertised FEC modes: Not reported
  Speed: Unknown!
  Duplex: Unknown! (255)
  Port: MII
  PHYAD: 2
  Transceiver: internal
  Auto-negotiation: on
  Link detected: no

  ( Why Speed and Duplex is unknown ?? It looks to me PHY is not attached to MAC ...)

- Other info
  eno0 works with other software using default SD card, and OpenIL code.
  So, I believe the hardware itself is OK.
  I just can not make it work using Layerscape SDK...

Thanks, Pavel

But I could not make it work..
Let me ask couple of questions.

1. Is your environment the same as below ?

- Environment
  - Hardware
    - LS1028ARDB
- SW
  - LSDK 19.09
 

2. Did you use the pure LSDK19.09 or have you modified the kernel ?
$ wget https://www.nxp.com/lgfiles/sdk/lsdk1909/flex-installer
$ flex-installer -i auto -m ls1028ardb -d /dev/sdb

Pavel,

May I have your answer on this ?

Thanks.

Have a great day,

With LSDK20.04, it worked with the procedure above...
I'm very curious what's wrong with LSDK19.09.
Thanks.

[Pavel]

Check your default gateway. Similar command can be used for changing default gateway:

route add default gw 192.168.99.98 eno0

Have a great day,

Pavel,

Thanks for your reply.
Have you successfully make it work on eno0 on LSDK19.09 on LS1028A RDB ?
If so would you please share the step ?

I think it is not likely the gateway setting...
The reason is because of this command results..
This mean the interface is not be attached to PHY driver ...

$ethtool eno0
Speed: Unknown!
Duplex: Unknown! (255)

Search QLINUX-12862 in LSDK user guide.
Workaround: Bring down and up again the ENETC Port0 ethernet interface.
