can't open 3 channels in one adc module

[duwufeng]

      I  use the mqx3.8.1 and mk60,I want to use 3 channels in adc0 module,but the first and second second channel can be opened,the third channel will open failed.

      my adc channel initial structures are right,and if I change the channels open sequence,always the same result,only the third channel can't work.how can I handle this???

thanks !!!

the problem has been solved, because of the mk60's hardware configuration.
