Hi, Greetings! I am trying to put openwrt on Atheros PB92 board and I get "Kernel panic - not syncing: No init found. Try passing init= option to kernel."
I took the kernel and jffs2 files (openwrt-ar71xx-generic-pb92-rootfs-jffs2.bin openwrt-ar71xx-generic-pb92-kernel.bin ) from http://downloads.openwrt.org/snapshots/trunk/ar71xx/ and upgraded to my board using tftp. I used following commands to upgrade the board: tftp 0x80060000 openwrt-ar71xx-generic-pb92-rootfs-jffs2.bin erase 0x9f010000 +0x2f0000 cp.b $fileaddr 0x9f010000 $filesize tftp 0x80060000 openwrt-ar71xx-generic-pb92-kernel.bin erase 0x9f300000 +0xe0000 cp.b $fileaddr 0x9f300000 $filesize I noticed that there is not init= passed to the kernel. The entire message looks like this: "Kernel command line: rootfstype=squashfs,jffs2 noinitrd console=ttyS0,115200 board=PB92" Then I compiled the source code from trunk with init=/etc/preinit option in the default kernel parameters. With this the kernel command line looks like this: "Kernel command line: rootfstype=squashfs,jffs2 noinitrd console=ttyS0,115200 init=/etc/preinit board=PB92" And the error message looks like this: "Failed to execute /etc/preinit. Attempting defaults... Kernel panic - not syncing: No init found. Try passing init= option to kernel." Am I missing something or am I doing something wrong? Any help would be appreciated. Thanks. -Rafiq. -------------------------------------------------------------------------------------------------------------------- Here is the detailed boot messages: ## Booting image at 9f300000 ...
