ELDK 3.1.1 ramdisk

[Clement Fabien]

Hi,

Make sure ROOT_DEV is initialized to the correct device, for instance :

In Sandpoint.c (arch\ppc\platforms):		

#ifdef	CONFIG_ROOT_NFS
	ROOT_DEV = to_kdev_t(0x00FF);	/* /dev/nfs pseudo device */
#endif

There is no default value for it, except if you pass it on command line

Fabien

HI , 

  I am using MPC862 with 64mb ram , with Denx 3.1.1 eldk 
with linux-2.4.25 on my custom board. 
on Uboot i use SMC2 as my serial console , when i load linux i use SCC4 as my serisl console , this is becuase i dont have any idea why my SMC2 is not working , it works fine on my linux-2.4.18 kernel , 
anyways thats not the problem ,

i am using ramdisk_image.gz provided by eldk , and i have configured kernel wit intial ramdisk support , i have attachec the config file below , and also the booting messages in another file . as i chnages the console from smc2 to scc4 from uboot to linux may be intial message is not clear , 
i always get kernel panic VFS unable to mount root fs , is there something else i need to do or i am missing very important configuartion , please throw some light 

thanks in advance
