I bought an odroid-hc4 several months ago. I plan to build up a headless tvheadend server to store movies on the sata devices of the hc4.
A main goal is to set the system to sleep as long as nobody is using it or no recording is running.
I found a lot of problems with suspend/resume, reboot and poweroff, regardless of whether I used hardkernel 4.19 kernel, different tobetter kernel versions or armbian distro.
For this reason, I started to build up my own odroid-hc4 kernel based on the current stable 5.15.y version.
The current status is as follows:
- Eth irq problem fixed
- Reboot works fine
- Wake on lan support is working (poweroff)
- RCT wake up support is working (poweroff)
- Suspend/resume is still not working. Main problems are the missing suspend/resume support of meson-pci, ahci sata implementation and suspend/resume problems of other devices.
You can find my odroid-hc4 kernel source branch at https://github.com/theleks/linux-odroid ... hc4_5.15.y
I look forward to your feedback and I hope this can help someone.
