Hopes for Pine64 dashed
#1
Hi all. My recent attempts to find a new use case for the Pine64 have been dashed on my particular hardware. I keep coming up against road blocks.
A recent attempt to Install and run Asterisk on Armbian Stable proved problematic. As posted on the Pine-Armbian sub-forum, I found a Call Trace in the kernel and
had to question its suitability for this task. Now, with a new install of Archlinux with kernel (4.20.0-2-ARCH) I find that problems with the Pine64 persist. Not sure where to go from here. The Pine64 worked fine for Android 6,7 as a media box. Your thoughts ..
