Yotta install on windows

Mbed OS

I have a working install in Windows but have a problem with:

Microsoft Windows [Version 6.3.9600]

C:\WINDOWS\system32>cd C:\FreeScale\mbedos\blinky

C:\FreeScale\mbedos\blinky>yotta search blinky
blinky 0.0.0:

blinky

C:\FreeScale\mbedos\blinky>yotta install blinky
info: get versions for win
error: could not install target win at for win
error: win does not exist in the targets registry. Check that the name is
correct, and that it has been published.

C:\FreeScale\mbedos\blinky>

The search functions ok but the install fails. Your help would be appreciated.

@kg1 what are you trying to achieve? You haven’t set the target (check yotta Documentation - Using Targets to Compile for Different Platforms ).

Looking at yotta install command help -

Add a specific module as a dependency, and download it, or install all dependencies for the current module.

It fetches the dependencies (=target dependencies) for win target. win does not exist yet as yotta target. Please set the target first, something like frdm-k64f-gcc.

@Kojto
Thank you Kojto. If I understand you correctly yotta install is used to add dependences not to establish an example project. Hence I when directly to:

Is this an executable (instead of a re-usable library module)?

yotta init is for creating a new yotta module. When you clone already existing yotta module (=app in this case), set your target, build, then use either yt debug (pyocd gdb or uvision currently supported there), or use provided binary in the build/‘your_target_name’/source/‘example_name’.bin/.hex

The shared output with dir is not much readable, please use code highlighter if needed to share cmd line output.

@kojto Thank you for your reply. Please guide me to the editing tips for this forum. The document for “Running your first mbed OS application” has been updated since I read it. I apologise for any misunderstanding on my part.

Try these two videos, they should help clear up how to use yotta:
