Hi, I am having a problem getting a ramdisk image to start correctly. I am building for an RPX-Lite target using a 2.4.19 kernel and a ramdisk image containing Busybox (statically linked against uClibc), TinyLogin Net-Snmp and Zebra built using uClibc shared libraries. If I run the kernel and use the file system over NFS then the system boots and runs as expected, if however I build the ramdisk.image.gz and use make zImage.initrd it starts but there is a problem with the file system. The relevant messages are as follows:
RAMDISK: Compressed image found at block 0 crc error<6>Freeing initrd memory: 1251k freed VFS: Mounted root (ext2 filesystem) readonly. Freeing unused kernel memory: 52k init init started: Busybox v0.60.5 (... # mount rootfs on / type rootfs (rw) /dev/ram on / type ext2 (rw) proc on /proc type proc (rw) # snmpd EXT2-fs error (device ramdisk(1,0)):ext2_check_page: bad entry in directory #22 EXT2-fs error (device ramdisk(1,0)):ext2_check_page: bad entry in directory #20 snmpd: No such file or directory # ls -l sbin/snmpd -rwxr-xr-x 1 0 0 760916 Nov 21 2002 sbin/snmpd I am cross-compiling from a PC for the target. It appears that the ramdisk image is corrupt (crc error<6>) and yet busybox works correctly, only the dynamically linked applications fail. If I unzip and mount the ramdisk.image.gz file the filesystem check says it is okay. I am assuming I have missed something either in the build process or in my configuration of the system. /etc/inittab is: ::sysinit:/etc/init.d/rcS ::respawn:/bin/ash ::shutdown:/etc/init.d/umountfs ::restart:/sbin/init /etc/init.d/rcS is: #!/bin/ash /bin/mount -n -o remount,rw / # Clear out mtab > /etc/mtab /bin/mount -a /etc/fstab is # <file system > <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 /dev/ram / ext2 defaults 1 1 Any ideas would be appreciated.
