I am going to double check with one of the Hardware engineers to see if he has any concerns about the max current.
I was able to locate this web site at TI:
http://processors.wiki.ti..._Consumption_Summary In it, there is a spreadsheet to download. I would suggest that you fill it out enabling the various peripherals, etc. for your application if you don't have the Wattson hardware for measuring power.
Because the development kit was obsoleted a while ago by TI (then by us), it took me a while to find one. I'll try to have something for you tomorrow on what the base Linux installation uses for power.
