I'm trying to make new directories, create files, save
changes to files, etc. and when I reboot my changes
are not being saved. I'm sorry if this is vague, but
I haven't run into this problem before in previous
kernels. I'm using 2.6.25 and my configuration is
very similar to mpc8313erdb_defconfig, with changes to
include NAND support as my flash device is a NAND.
Also, my dts is very similar to mpc8313erdb.dts as
well. I don't know where to start looking for the
problem as there is no error. Here is what is printed
on boot.
