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.
What you're asking is really beyond the scope of this forum - you need to find a Wear OS support community for those questions. They have nothing to do with Keil.
A more fundamental question is: do you really need Wear OS - or anything like it - at all?
What is it that you're actually trying to build? Why did you think that a Cortex-M4 would be suitable?
As with any project, you should start with the requirements of your project - and then find things with which you can meet those requirements.
"Wearable" is largely meaningless as a technical specification - it's mostly just a marketing buzzword.
Doesn't stop sa1esmen asking for these things though.
Dumbest technical specification i received was when sa1es asked if we could develop some sort of wearable fridge (to be placed in a backpack). When asked for further details they came back with "it must be cold". I didn't bother staying there long.
Indeed.
It's the engineer's job to turn the sa1es request into a technical specification.
"some sort of wearable fridge (to be placed in a backpack)"
Now seen on the backs of Deliveroo operatives everywhere ?
(although I guess they need one that can do hot and cold)
I want to make a watch that will basically measure heartbeat,accleration, velocity, stepcount, will be having gps,wifi ;more or less the same functions as a commercial watch which use some form of os, mostly wear os running on a snapdragon wear 3100 ,the same thing i want to implement on Cortex A series since wear 3100 is not available but i want to know whether it is possible;also since wear os is also not available what other os can be deployed in such applications on cortex A. I think the question becomes more clear and relevant to the forum now.
Thanks
"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/
