Mindtribe has trouble loading firmware on the lpc824 with new installations of coretools (py2 or py3)

They have a working installation with python2.7 however they are unable to recreate it.

WORKING PYTHON 2 VIRTUALENV INSTALLED A FEW MONTHS AGO
The commands used were something like this:
```
virtualenv --python=python2.7 iotile
source iotile/bin/activate
sudo pip install iotile-core iotile-test iotile-emulate iotile-transport-bled112
sudo pip install -U iotile-support-con-nrf52832-3 iotile-transport-jlink iotile-support-lib-controller-3
sudo pip install iotile-sensorgraph
sudo pip install iotile-build
sudo pip install iotile-ext-cloud
