Following pxt-microbit readme throws an error at pxt serve

[adamcarriere]

Trying to get a pxt dev environment set up so I can create my own target, starting by trying pxt-microbit.

Following the instructions in the pxt-microbit README gives the following output when running pxt serve:

Cloning the pxt-microbit repo next to the pxt repo, following the Build instructions, and running jake serve gives:

These instructions for the Command Line Tool work fine:

mkdir microbit
cd microbit
pxt target microbit
pxt serve

It should also be noted that the Target Creation instructions also fail to run with pxt serve

Hopefully I'm just overlooking/missing something simple. This is all happening on Windows 10.

Make sure you have yotta installed and in the path. http://docs.yottabuild.org/#installing

[adamcarriere]

Almost!

Now I'm getting:

'srec_cat' is not recognized as an internal or external command,
operable program or batch file.
ninja: build stopped: subcommand failed.
error: command ['ninja'] failed

I'm assuming I need to install srec_cat now?

[adamcarriere]

Okay I got everything up and running!!! 😄 🎆

Steps needed:

1. Install Yotta (manual install for Windows)
2. Make sure C:\Python27\Scripts is in the Path
3. Download SRecord 1.64 and move it to C:\
4. Add C:\srecord_dir to the Path

Can this be added to the documentation?

Care to package your first PR? :)

[adamcarriere]

Done!
