Hi, I currently try to build a kernel (3.14) for a SIMpad tablet (StrongARM SA1100). I'm not sure whether my problem is appropriate for this mailing list, just ignore it if it should ask somewhere else.
The kernel does stop after it tried to execute the init process. Error message: "Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004" I already tried to use a different init process (busybox instead of tiny-init) however nothing changes. Are there any options or tools I can use to further track down the problem? Thank you for your support. Cheers, Andreas Wick
