Rock64 4K new board; test burn-in

[MarkHaysHarris777]

   


I got the M3 mounting hardware today;  typically I use M3 metric machine screws to mount my boards ( cased or not ) with a double set of washers|locknuts to adjust for height ( in and out of the case );   when not cased the M3 bolts make very nice stands|legs and since they are connected to ground 'bleed' very well to static desktops, mats, etc.

If you use this technique be careful because some of the components are very close to the mounts!  Also, the holes on the Rock64 board are too small for M3 bolts ( just barely ).  If you're careful, you can gently 'machine tap' them in with a hand driver and the legs are then very firm;  frankly,  the washers and nuts are not even required if all you want are legs !

Its still a do nothing machine for now;  haven't really stressed it and have just been having a good time testing the images (installs and config) and doing some terminal work with C and Python.

Note:

  I got to the bottom of the system running very cool;  with low clock rate --  408.00Mhz

The governor is set to interactive mode , and the serial console does not count as "interactive" because uart networking does not trigger the governor;  setting the governor to "ondemand" bumps the freq both for uart and for smallish python scripts ;  which gives a more realistic picture.

However, if all you care to do is lite computing via uart console  using only passive cooling without heatsink, the Rock64 performs quite will and runs cool as well.
