Hi, yes i have set the wrong uboot var, but when i append ro to the right var, the system won't boot, the services cannot start because of ro system.
but forgot about this error, i have build a new minirootfs with the buildscript, and installed the new rootfs to the dreamplug. I can boot into the system, no ro error , and i have not set the uboot vars to ro. but i get a kernel oops during boot, and the boot hangs for some time. (see attached oops.txt) i think this come from missing modules.
