I want to make a wearable smartwatch which works on keil mcbstm32f400 running android wear/wear os ,i want to know the procedure how to install wear os on the dev board.I did some research and i got to know that that only some devices have wear os like qualcomm's wear 3100 and ti omap but they are not available for purchase so i also got to know about other os like tizen which can also be used for wearables but i am stuck at which one to choose ,how to start , how to install on the board.Please guide how to proceed.
"I think the question becomes more clear and relevant to the forum now"
No - it becomes clear that this is not a question for this forum.
This forum is for Keil microcontroller products; what you are talking about is not a microcontroller project.
As previously noted, Wear OS (and Tizen) is basically a Linux platform - which is not where Keil tools fit.
So , no keil product supports A series processor?
Have you checked?
What do the Product pages tell you ... ?
Some devices support like ARMCA9 so the question becomes relevant to the forum. I checked here:http://www.keil.com/dd2/
