Greetings!
System details:
Board: DTSP-ARM926Ej-S(new board)
Cross-toolchain: ELDK4.1

u-boot: 1.1.6
I have been able to successfully run u-boot and linux kernel with root file
system but when kernel is start the following error message
come.........."kobject_add failed for tts/0 (-13)"
The complete log is following:
