Hi,

 

I am getting a kernel panic error while booting my P4080DS board.

init[1]: unhandled signal 11 at bf20aff0 nip 0ffdda20 lr 0ffddaf4 code 30001

Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

Rebooting in 180 seconds..

 

Could anyone please help on the issue?

 

The board was earlier updated with SDK 1.7 including u-boot, file system, kernel, device tree and it was working fine.

 

Following are done on the system just before I got this error:

Trying to achieve better performance, I tried to optimize the entire SDK, for which I edited the following optimization flags in poky/meta/conf/bitbake.conf.

 

DEBUG_FLAGS ?= ""

FULL_OPTIMIZATION = "-O3 -pipe ${DEBUG_FLAGS}"

DEBUG_OPTIMIZATION = ""

SELECTED_OPTIMIZATION = "${@d.getVar(['FULL_OPTIMIZATION', 'DEBUG_OPTIMIZATION'][d.getVar('DEBUG_BUILD', True) == '1'], True)}"

SELECTED_OPTIMIZATION[vardeps] += "FULL_OPTIMIZATION DEBUG_OPTIMIZATION"

BUILD_OPTIMIZATION = "-O3 -pipe ${DEBUG_FLAGS}"
