I have stability issues using the R4C+ headless, LAN, not WIFI
- tried several distros, currently Dietpi
- added eMMC to rule out µSD issues
- tried different power supplies via USB-C, will try GPIO 5v next (my PI never draws more than 1,5A@5V)
- I think this is the only Rock 4 that does not support USB 3.x PD…?!
checked with thermal imaging and I am surprised, where the heat is mostly present. in this order:
- Rockchip RK809-3 Power Mgmt front and backside of the Rock
- Radxa RA620-1 HDMI DP stuff
- CPU only under load
How can I turn off HDMI?
Do I need a heatsink on the PMU?
top left with the cross = PMU, top right at the USBC Port = HDMI
