Hi John, Thanks for your reply. I'm new to linux systems, much less embedded linux systems.
How would I know if I'm using NFS and systemd? I'm currently in the processing of flashing bbb, so I don't know if this new version of bb will be the same as before. Also, I thought enabling the SPI was an internal process? From what I've been reading about NFS and connman they talk about internet connections etc. I'm a bit confused. What's the difference between uEnv.txt vs nfs-uEnv.txt? Thanks! On Friday, February 19, 2016 at 9:34:48 PM UTC-5, john3909 wrote: > > I’ve had this problem myself.
