Finally managed to upload the correct BenF firmware update to my Nano V1 after some issues (see my post at http://www.seeedstudio.com/forum/viewtopic.php?f=22&t=4823&start=50) but it’s now stuck at the system initializing screen, displaying:
BenF
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?
