Hi guys,
My Helios64 keeps going offline, it has this red light come on the front panel but i am not sure what it means exactly.
This happens once every few weeks, the system is fine after a reboot.
What does this red light mean exactly? Is there anything i can do to prevent these breakdowns?
Cheers,
VDD_LOG powers internal logic circuitry such as SRAM, clock & reset Unit, PLL, internal MCU.
VDD_CENTER powers mostly vpu, encoder/decoder but it also powers DDR controller.
Recommended operating condition for those supply is 0.9V
but we have found other RK3399 board, RockPro64, increase this to 0.95V to improve stability
