My kernel command line is set as follows in include/configs/ml300.h

#define CONFIG_BOOTARGS "console=ttyS0,9600 root=/dev/nfs rw \ nfsroot=135.4.21.60:/opt2/timesys/linux/4.0/amxap100/rfs \ rootpath=/opt2/timesys/linux/4.0/amxap100/rfs \ ip=135.4.21.155:135.4.21.60:135.4.21.254:255.255.254.0:prolab6::off"

However when the kernel outputs its command line during the boot process I see:

"Kernel command line: console=ttyS0,9600 root=/dev/nfs rw nfsroot=135.4.21.60:/opt2/timesys/linux/4.0/amxap100/rfs rootpath=/opt2/timesys/linux/4.0/amxap100/rfs ip=135.4.21.155:135.4.21.60:135.4.21.254:255.255.254.0:prolab6::off"

Then, later I see:

"IP-Config: Complete: device=eth0, addr=135.4.21.155, mask=255.255.254.0, gw=135.4.21.254, host=prolab6, domain=, nis-domain=(none) bootserver=135.4.21.60 rootserver=135.4.21.60 rootpath="

Note that rootpath is now empty, even though I set it on the command line.

Can somebody give me a clue?

my config

IP-Config: Complete: device=eth0, addr=10.10.10.2, mask=255.255.255.0, gw=10.10.10.1, host=xcep, domain=, nis-domain=(none), bootserver=10.10.10.1, rootserver=10.10.10.1, rootpath=

my rootpath is also empty but i have 'xcep' dir that matches my target name under /tftpboot like: /tftpboot/xcep/<root fs>

I previously had different dir on tftp server but using this config saved some issues with booting linux...

IMHO, if your fs does not get mounted this is not the issue.
