BenF System Initialization Time?

Finally managed to upload the correct BenF firmware update to my Nano V1 after some issues (see my post at but it’s now stuck at the system initializing screen, displaying:

System initializing
Please Wait

then the correct LIB and APP versions.

Question is, how long should this process take? Or have I missed a step?

Sorted now, i think. Waited 30mins at the initialization screen, got bored, switched the DSO off/on and it now boots up fine.
