Hello.

After about a hour of usage server.py refuse to work with RuntimeError: ws2811_init failed with code -5 (mmap() failed). No hits, drops, all wirings looks good, batteries are fresh. AWR boots fine but this error. How can one debug this issue with ws2811 ?

Thank you for any help.

Pls refer to Chapter 9 of our new version tutorial 9 How to control WS2812 RGB LED to test what went wrong, or directly use our made image https://www.adeept.com/learn/detail-35.html and check whether the the connection of the cable of WS2812 is loose. It will prompt this error, if the cable is loose.
