Device unable to boot
06-22-2021, 08:17 PM
I've just looked through the posts you've recommanded.
I've flashed an os on the SD card I know has HDMI output (Armbian Buster) and did some more testing.
I've tried the power + reset solution by pressing both at the same time for 2 sec and doing a 2sec power followed by 2sec reset then pressing the power button once more to power on the device but without any result all no white led, nor any HDMI output.
When it comes to the power and reset pin holes next to the audio jack, I've tried jumping the power and ground as in this post (https://forum.pine64.org/showthread.php?pid=77022), it just powered off the device. From what I can understand those pins are the same as the buttons, unless I've misunderstood what they are used for.
For the `(or on power off touch all the gpio pins before)` part, I'm not sure I get what you mean by that.
On the serial interface side of things. I didn't expect there could be fake FTDI IC, but after some research, I found my FTDI programmer might be a fake.
So far it worked just fine with lower speed devices like some other SBC and dev board, but maybe not with this board.
I've ordered a new serial interface with a genuine FTDI chip and will try to see if I can get any output out of the board once I'll receive it.
