Default GPIO PIN state after boot |

PROBLEM: Random pin state (or pin ON) after boot.
can anyone tell how to define the state of pins after boot?
After booting my Rasp PI 2 all GPIO pins are off. After booting Pine64 GPIO pins have random state. Is anyone can help to set GPIO pin to off during the boot process?
This is a very serious problem. For example if you use a relay to control the lighting it's not very scary, but if connected leading pump? It will deflate all of the water and burn in case of failure when starting the main control program.

I opened th Micro SD card that was delivered with the Pine64 board
and saw the following list of files on the card.
Volume in drive Q is BOOT
Volume Serial Number is 424A-49A2
Directory of Q:\
05/07/2016 19:22 <DIR> pine64
05/07/2016 19:22 1,076,704 initrd.img
02/11/2016 16:28 137 uEnv.txt
11/03/2016 15:46 0 list_Q.text
3 File(s) 1,076,841 bytes
1 Dir(s) 39,806,976 bytes free
What are these files?
Why is the SC Card called BOOT?
If I download an image of Linux from Pine64.com to install it
on the SD card, must I first delete those files and format the SD Card?

ARM Trusted Firmware and date time related problems |

Hello, I have a Pine64 with 1GB RAM and GBE.
I use Ubuntu on the Pine64. The kernels and roots created by longsleep and ARMBIAN (based on longsleep work).
I use Pine64 as a headless server, but regardless the use of ntpd or timesyncd, system clock always forward and loose time sync.
Hardware clock appear to be correct, but once the system clock forward no other command could set to correct time.
In less than 24h the time forward no less than 16 minutes.
Talk about it on IRC, apritzel user, point me that the root of the problem could be ARM Trusted Firmware, but he said that longsleep fix it in the past.
How could I check if my ARM Trusted Firmware is updated ? How could I update it ?
I found this repository https://github.com/longsleep/arm-trusted...are-pine64
[url=https://github.com/longsleep/arm-trusted-firmware-pine64][/url]It has 4 branches and I do not know how to install on a running system.
Someone could help me ?
Thanks.
