SOC getting very hot; no boot. - dtkenmo - 02-20-2018
Hi all:
My employer ordered several Rock64 units for possible app development. One of these that I have been working with has developed a heat problem with the SOC (Rockchip). It was getting too hot to touch under idle conditions, so I mounted a heatsink to the chip but it still got super hot. Then it stopped booting and is now dead. Anyone have any idea what may have caused this? I used the standard PSU that came with it (puts out 5.1 v.). I had no hardware connections to it other than HDMI & USB. So I replaced it with one of the working units (which does not get more than warm to the touch running our app) and have had no problems with that unit. I'm wondering if maybe the supply regulator for the SOC had shorted internally.

If too hot to touch, looks like the board has turn bad.
