Hi, vishnu Thanks for quick reply. I've executed 'printenv' on my Tattoo device, 'CMDLINE' environment value isn't there. I guess it should be set in BoardConfig.mk file, right? There is an item named 'BOARD_KERNEL_CMDLINE' in this file. Right now, I set it to 'no_console_suspend=1 console=null' as Google did for other devices.
Is this correct?
