As I am not getting help to solve this error by the existing posts, I have to open a new one to get this problem solved for all times.
The following setup:
- a fresh install of Raspbian stretch lite, Nov. 2018
- modified /boot/config.txt with: core_freq=250 as per recommendation from previous post
- modified /boot/cmdline.txt with: spidev.bufsiz=32768 as per recommendation from previous post
- installed Hyperion via HyperCon (as I am too dumb to get hyperion.ng running properly)
- uploaded a minimalistic config.json via HyperCon and even insertet "dmanum=10," (due to freezes I experienced some time ago when using Kodi-releases) --> ws281x driver, no V4L2 grabber, just internal grabber activated, just 20 LEDs for testing
hyperiond starts perfectly and keeps running, but the LEDs won't do anything. When using hyperion-remote command, nothing happens for 1 minute until the 'Error while reading data from host' occurs.
Now the most curious thing is, that it will take at about 1.5 hours of just waiting and the problem is resolved and the LEDs keep functioning as they should.... I cannot understand this behaviour at all.
Please, does someone have an explanation to this?
Just in case you ask, I'll post the latest log of my setup here:
