Occasionally won't boot

[MarkHaysHarris777]

I already said above that the power adapter and its connector which has been powering my Raspberry Pi 2 without issues for quite awhile works only intermittently with my Pine64 board.  Also, I read/write checked the last brand new Class 10 32GB card exhaustively before writing an image.  The image on the new card fails intermittently on Pine64 boot.  When I tested the raw disk image with a full raw device scanner afterwards, no errors are reported.

Maybe there is a faulty power connector on the board.  Maybe there are bus issues somewhere on the board.  In any case, it's the board.  I have invested enough time on this board.

If you don't want it to work, that's ok too.  Its not the board until you debug the boot-up with a serial console cable. If you want it to work, you'll try that... if you don't want it to work, throw it away.

The power requirements are more exacting on the PineA64+ than they are for the RPi2.  You can't use the RPi2 in this case to determine that your PSU is ok ( I'm telling you the truth ).  For instance, the RPi2 does not have an AXP803 PMIC on-board.  It is very sensitive; and noise on the PSU, or bad connector, and the board will not boot;

If you want to make the board work get a Samsung Class 10 Evo Plus SD card ( 32G is good ) , power the board via euler bus  pins(2 or 4   +5v)  pin(6  ground),  and use a serial console cable to watch the boot-up to find out where its hanging up.  My guess is that if you use a Samsung evo plus card, and power the board correctly, it will run for a long long time.



PS   Its like the ancient text says,  "Do you want to be healed ? "
