Issues about PM Debug on IMX6DL

[tony_l_cai]

Dear all，

     I have read the article  Android Power Management on i.MX6DQ/DL

and  “All PLLs will cut off, just 32KHZ sleep clock living (FSL done)” ，how to check？

could you give me more in details？

Thank you~

Hi tony

one can output necessary clock to CLKO1,2 pin and check

it by oscilloscope using register CCM_CCOSR, add debug code

to sources or use memtool for writing to CCM_CCOSR.

Best regards

igor
