Other Parts Discussed in Thread: AM3517, TCA8418
Hi all.
I try to boot this board http://sauris.de/index.php?page=products&id=5&lang=en from TFTP with NFS filesystem.
I load u-boot from SD-card. U-boot successfully downloads uImage by TFTP, but on mounting the file system from NFS, kernel fails with error Cannot open root device "nfs"
Also, NFS directory successfully mounted on another PC in the same network.
The options for u-boot are the next (with static ip)
setenv serverip 192.168.55.26
setenv ipaddr 192.168.55.25
setenv netmask 255.255.255.0
setenv gatewayip 192.168.55.100
setenv bootcmd 'tftp 0x80000000;bootm'
setenv bootfile uImage
setenv rootpath /home/master/target/targetNFS
setenv nfshost 192.168.55.26
setenv bootargs console=ttyO2,115200n8 noinitrd rw ip=192.168.55.25:192.168.55.26:192.168.55.100:255.255.255.0 root=/dev/nfs nfsroot=${nfshost}:${rootpath},wsize=8096,rsize=8096 nolock mem=256M
This is kernel boot log:
Using DaVinci EMAC device
