how to enable serial console during android suspend?

Hello,

 

I have a custom IMX6D board running android based off the sabresd android JB 4.2.2 release. A lot of our debugging is done over the serial (UART1) console. When android goes into its low-power suspend state, the console becomes un-responsive. Only way to 'wake up' the console is to press the power button, which also brings the entire system (including display) back up.

 

Is there any way to have the system enter low power suspend state, but keep the serial console enabled for debug purposes?

 

I've tried adding 'no_console_suspend' to the boot arguments for kernel, but the console still goes dead when the system enters suspend mode.

 

Stumped,

Abraham V.
