Hi,

This could be related to this issue.

Try to run this to update to the newest west version (0.6.2) and then try west update again.

pip3 install west --upgrade

If that for some reason fails, try

pip3 install west==0.6.0 --upgrade

Looks like you need to stash your changes. Try this command:

git stash

If that does not work, do a git fetch and a git pull, before doing west update

Yes. Indeed west was having trouble with mbedtls due to a developer error.
Updating west and and its dependencies fixed the error.

The easiest way to overcome the 2nd problem (above) is to make a git checkout and force it to remove any old stuff.

cd ${NORDICS}/ncs/nrf
git checkout -f master
git pull
git checkout v1.0.0
west update
