Hi All, I have downloaded kernel/common.git from android git server and linux-2.6.35 branch, I am trying to port this kernel with froyo on my hardware. i the kernel i have only ported serial (UART) driver along with MTD driver (which is onenand device in this case). I dont have any framebuffer or console driver ready yet. I have build the froyo and i am using yaffs2 filesystem. when i booted i got Kernel panic - not syncing: Attempted to kill init! i wanted to debug this problem but do not know where to start. my question is, what is the reason for init to fail? Do i need some other driver like frame-buffer or console driver to be ported first? my requirement is to get the Android (linux) prompt not the android GUI or so. and also tell me how to debug the init of android? i increase the loglevel to 6 in init.rc but it doesnt help.
Appreciate any input on this, below are the kernel log: ****************** Starting kernel ... Uncompressing Linux... done, booting the kernel.
