Hi All,
I am porting linux2.4.24(which comes with ELDK) on mpc8260
based custom board.
I am using the JFFS2 flash file system which i had placed in the Flash
memory at 0xFC00_0000, but i couldn't find any variable or macro in
the code which i could set with the base address of the flash file
system.
this is what i am getting on the screen when i tried to bootup the Linux .....
