Power light flashes on then nothing

[MarkHaysHarris777]

I will add in addition:

... you can plug a serial tty cable into the uart0 , EXP header at pins 7,8, and 9 (ttyS0)

pin(8) is the Rx pin... plug your Tx line here , usually green

pin(7) is the Tx pin... plug your Rx line here, usually white

pin(9) is ground... plug your black ground wire here

WARNING VERY IMPORTANT

Use only a serial ttl bridge set for 3v3 (NOT 5V) !!! or you will toast your Pine board... words to the wise.

(all the cables from ada fruit [pl2303 based] use the 3v3 setup, be careful to not touch the 5v (red) line to anything !! )

Use a serial ttl to usb bridge cable like the one from ada fruit (PL2303 based) or you can use a similar cable that is CP2102 based. Plug the usb adapter into your PC (I use a gnu+linux Mint system) and a comm program like 'screen' or 'minicom' or similar vt102 emulator.

Now you can 'watch' the bootup progress, regardless of what happens on the hdmi screen, and you can see where its dropping out and powering down.


Also, if you visit us live on the chat site, I can help you easier on-line live, than here on the forum. I'd be happy to help you, and I'm hanging out there most days... and some nights.

Please read my previous post...

... just to be complete, although perhaps pedantic, it is 'normal' for the PineA64 to poweron with the 'red' light on momentarily, and then go off--- IF you power-on the PineA64 with the power button and the battery IS NOT plugged in.

Please don't misunderstand me. You do not need a battery; however, IF you do not have a battery you cannot power-on the pine board with the power button-- in this case you will need to power-on the pine board with the power cord alone. Unplug the PSU power cord, count 5, plug the PSU power cord back in (don't touch the buttons).
