Problem with Power Monitor in Jeston TX1

Hi, I am a freshman using TX1.
I notice that Jetson TX1 (revision 300 or greater) enables the use of INA monitors for the module and Developer Kit carrier board.
but it just can be used for Jetson TX1 (revision 300 or greater), I notice that my board revision is 100.
so is there some ways to access the power information?
I notice that the following link offered a way to get the power information for earlier revision. but lots of people find that is not useful, the code can’t successfully run.
Is there have any available way to get power information of earlier revision of TX1?
Thanks too much for helping.


Due to some accuracy issue, we don’t enable ina3221 in earlier modules. As kayccc’s comment in

Please buy later revision if you need such feature.
