Hi, I am porting Linux kernel 3.9.0 to my device which is having android 4.1 & kernel 3.0.3.
With android kernel 3.0.3, it is booting properly. But after flashing my build kernel 3.9.0, I am not seeing any initial kernel logs i.e "Uncompressing Kernel.. Booting is done". We have verified machine ID & zreladdr etc. passed from bootloader and configured in kernel are same. Please help me if someone knows how to solve this problem. If any assistance provided in debugging arch/arm/bootp compressed folder, It would be great help. -------------------------------------------------------------------------------------------------- serial log with Linux 3.0.3 ----------------------------- ......ATAG_CORE: 5 54410001 0 0 0 MEMCONFIG: 20e01323 20e01323 ATAG_MEM: 4 54410002 10000000 40000000 ATAG_MEM: 4 54410002 10000000 50000000 ATAG_MEM: 4 54410002 10000000 60000000 ATAG_MEM: 4 54410002 10000000 70000000 ATAG_SERIAL: 4 54410006 175d762f 464119ec ATAG_REVISION: 3 54410007 c ATAG_CMDLINE: 3d 54410009 ': loglevel=8 console=ram sec_debug.enable=0 sec_debug.enable_user=0 c1_watchdog.sec_pet=5 sec_log=0x200000@0x5ea00000 s3cfb.bootloaderfb=0x5ec00000 ld9040.get_lcdtype=0x0 consoleblank=0 lpj=3981312 vmalloc=144m console=ttySAC2,115200' ATAG_NONE: 0 0 Starting kernel at 0x40008000...
