Ethernet not detecting with qcomlt-4.9 kernel


I have compiled qcomlt-4.9 using default configurations (distro.config) file. After booting, Ethernet is not detecting. same board I tried with qcomlt-4.14, Ethernet working. For my project purpose I have to boot board with qcomlt-4.9. can you please help me to solve this issue.

Can you explain a bit more. Kernel logs would be helpful (use pastebin or github gist to share them) and can you explain how ethernet is hooked up (Dragonboard 410C does not have ethernet).

Hi Danielt,

I used USB-to-ethernet converter to connect the ethernet. Actually there is no error shown on log. I am pasting 4.14 log here which is not coming on 4.9 log.

Just in case, could you try to remove any connection on micro-usb, It could force the board in device mode, this is not the case with 4.14 but don’t remember about 4.9 kernel.

Thanks, Loic,

After removing OTG cable, USB host mode is enabled and ethernet is detecting.
