More reproducible and predictable crashes at the same location:
Geekbench 3 – The system hangs (red power light behind VGA port glows, but the front green and red user LEDs stay off). This happens immediately after application is started (even before any test is executed)
CPU Prime Benchmark – On running the test (at the end of first stage prime calculation itself) the board hangs with both the user LEDs (green & red lit stably as well as the power light) either lit stably not not lit. The power LED stays ON.
3Dmark – Again the same thing happenned as with AntuTu in Graphics Test 2. Complete loss of power and shutdown. Just udden
GPU bench – Does not start properly. Initial screen is displayed without any contents.
The Overall graphics test tend to run a bit longer. Any CPU related stress test like prime number, single core test etc gives up fast. Also could this by any chnace be related to wrong CPU heatsink installation ? Before I put the heatsink, I could see some also rust colored deposit on and around a few CPU pins soldered to board.
Also forgot to note in my previous post that the device is CC-A80 V1.2 (2014-12-03) and not the V1.1 model (2014-08-26). Generally, I am am picking up everything from:http://dl.cubieboard.org/model/cc-a80/
I see only 1.1 documents here. Hopefully their are no MAJOR differences with the 1.2 version of the board and I have not ended up flashing the wrong image.
The board if left running in idle state through the night is perfectly fine and responsive in the morning. Only when some applications are run it goes down.
