? 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 Neelu -------------- next part -------------- An HTML attachment was scrubbed...
