Can you try to set some "root=something" into CONFIG_CMDLINE and
then add real "root=" param via 0xffff?
My problem is that I have specified ubifs mtd root in
CONFIG_CMDLINE and when I set correct root via bootloader (from
0xffff or flasher-3.5) it is ignored and used only what is
specified in CONFIG_CMDLINE.
