I build a Openwrt img for my Raspberry Pi 3B with the trunk code.But it has no network and wireless config file.
/etc/config/network, /etc/config/wireless
When I want to create one, it says read-only file system.
Then I get a new img from http://files.noltari.es/openwrt/rpi3/op … sdcard.img, It works well. Can any body help me?

#mount
/dev/root on / type ext4 (ro,relatime,block_validity,delalloc,barrier,user_xattr,acl)
proc on /proc type proc (rw,nosuid,nodev,noexec,noatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,noatime)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,size=512k,mode=755)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,mode=600)
debugfs on /sys/kernel/debug type debugfs (rw,noatime)

/dev/root mount read-only.

I have same problem on Cubietruck.
What i do: on console  mount -o remount,rw  /  and then paste same command in file /etc/config/sysfixtime  before boot() command,reboot - all work!
I know that is not good,but work fine! ))
P.S.Sorry for my English
P.P.S. Or mount sdcard with OpenWrt  and paste that command in sysfixtime ,first boot will be fine.
