I test Raspberry Pi v1, but I couldn't boot with NFSROOT through both onboard nic and RTL8152. I get following error.
VFS: Unable to mount root fs via NFS, trying floppy. Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)
However, if I start the system without NFSROOT, I could mount the nfs fs. Any idea?
NFS server: Fedora 24 Raspberry Pi OS: 2016-09-23-raspbian-jessie
Content of /etc/exports:
/nfsexport *(rw,sync,no_root_squash)
I change the cmdline.txt from
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles
to
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/nfs nfsroot=192.168.94.2:/nfsexport ip=192.168.94.22 rw rootwait quiet splash plymouth.ignore-serial-consoles
Best Regards, Hayes
