I used to be able to boot no problem with an older version of buildroot, but not with the latest. I'm getting the following kernel panic: VFS: Mounted root (jffs2 filesystem). Freeing init memory: 136K Warning: unable to open an initial console. Kernel panic - not syncing: No init found. Try passing init= option to kernel. I've loaded the NAND flash as follows: 0x00000000 - at91bootstrap 0x00020000 - u-boot 0x00200000 - kernel 0x00400000 - JFFS2 My bootargs are "mem=64M console=ttyS0,115200 root=/dev/mtdblock1 rw rootfstype=jffs2" The strange thing is if I change the bootargs to root=/dev/mtdblock0, I get a ton of jffs2 oob and ecc errors, but after a while, it gives me the login prompt. My JFFS2 memory type options are: Page Size: 0x800 Erase Block Size: 0x20000 Not using clean marker. These options never gave me a problem before. The only other thing I can think of is a message I get after a build of buildroot about skipping dev, tmp, and etc while creating the RFS: table='target/device/Atmel/root/device_table.txt' mkfs.jffs2: skipping device_table entry '/dev': no parent directory! mkfs.jffs2: skipping device_table entry '/tmp': no parent directory! mkfs.jffs2: skipping device_table entry '/etc': no parent directory! -rw-r--r-- 1 root root 7098064 Sep 23 09:47 /usr/arm/buildroot/binaries/at91sam9263ek/rootfs.arm-20080923.jffs2 rm -f /usr/arm/buildroot/project_build_arm/at91sam9263ek/.fakeroot* Something very strange is going on. Anyone else see this or have any suggestions? Thanks, Matt. -- Psssst! Schon vom neuen GMX MultiMessenger geh?rt? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger
