[privete repo] You need to have the latest from mbed – master and then create a new remote (this is the URL of the new repo). Then push from the current mbed – master to the new –remote master.

[pull request from private repo] I had to merge into my public repo using a branch and then make the pull request to mbedmicro mbed master
