Re: [U-Boot-Users] Ramdisk larger than 8M causes problem

Hi Robert,

I am facing a problem that ,I built a ramdisk(16M)  larger than 8M,

the kernel couldn't start up correctly with this ramdisk , the filesystem couln't be mounted and "kernel panic" happened. But if the ramdisk is smaller than or equal to 8M , it works fine. I tried the two method as what the website (http://www.denx.de/wiki/view/DULG/RamdiskGreaterThan4MBCausesProblems) said. but it takes no effect. Anybody gives me some hints?

This is really offtopic on the U-Boot ML, but anyway...

The 8MB are usually a compiled in limit for the size of ramdisks. You can either change CONFIG_BLK_DEV_RAM_SIZE at compile time or provide a command line parameter to the kernel, e.g. "ramdisk_size=8192k".

Best wishes Detlev
