rootfs ethernet boot with Yocto 1.8 (Fido) Distribution

Postby Franckl » Tue May 24, 2016 7:19 pm

Hello

I'm having a hard time configuring my varsom43 to boot from NFS. I used the std Yocto recipe and generated all the images. I burned a working SD card with the script and it boot juts fine. I installed a working TFTP boot setup and it does load the zImage and the device tree. But shortly after the kernel initialise the Ethernet ports it freeze.

I reviewed the boot parameters and they seems fine
I reviewed the kernel config and the NFS root option is enabled.

Did any body tried this? Any clue at where I can look next?

Thanks!



Here is a boot log from network
