 If you already have Zephyr installed but are having issues building the
 MicroPython port then try installing the correct version of Zephyr via:
 
-    $ west init zephyrproject -m https://github.com/zephyrproject-rtos/zephyr --mr v2.6.0
+    $ west init zephyrproject -m https://github.com/zephyrproject-rtos/zephyr --mr v2.7.0
 
 Alternatively, you don't have to redo the Zephyr installation to just
 switch from master to a tagged release, you can instead do:
 
     $ cd zephyrproject/zephyr
-    $ git checkout v2.6.0
+    $ git checkout v2.7.0
     $ west update
 
 With Zephyr installed you may then need to configure your environment,
