Is it usable with other user than root ?

Hello, I am trying to use GPIO in c and with wiringPi. I use GPIO_API_for_c. I can't pilot pins from my current user count. I need to be root to use it. And even this is not evident when I try to use Whatever I find on the web and test, nothing seems to work. Otherwise if I do this sequence I obtain weird result: nafa@tinkerboard:~$ sudo su root@tinkerboard:/home/nafa# echo 167 > /sys/class/gpio/export root@tinkerboard:/home/nafa# echo in > /sys/class/gpio/gpio167/direction root@tinkerboard:/home/nafa# gpio readall | grep 167 | 167 | 3 | GPIO5B7 | IN | 0 | 15 || 16 | 0 | IN | GPIO5B2 | 4 | 162 | root@tinkerboard:/home/nafa# echo out > /sys/class/gpio/gpio167/direction root@tinkerboard:/home/nafa# gpio readall | grep 167 | 167 | 3 | GPIO5B7 | IN | 0 | 15 || 16 | 0 | IN | GPIO5B2 | 4 | 162 | root@tinkerboard:/home/nafa#

I found the reason of the problem, It looks like there is a regression on the wifi support in the 5.30 version with 4.4.71 kernel. The 5.27 4.4.70 wifi works fine. Hope that the 5.31 will fix this. I think the problem is deeper than it seems. The wifi handshake between my Dell 6440 PC and the TinkerBox fail. If I use a TP-Link USB wifi dongle the handshake succeed and I can connect to the Tinkerboard. The handshake between my Chineese tablet under Android 4.4.4 fail. My smartphone which is under Android 5.1 connect to the Tinker, my other smartphone under Android 5.1.1 connect too. Might it be a wifi firmware problem ? A network-manager problem ? Might it could be useful to manually define a static hotspot in /etc/network/interfaces with a dhcp server ? Would be nice to have an answer from you.

Hello, I have a problem with wifi access point. I can define the access point but can't connect to it from any device. The status switch between Registered and try to connect. Otherwise the wifi can connect to my wifi router. I have the same result either with the 4.4.71 kernel or the 4.12 kernel. Might it be a symptom of wifi hardware disease ?

Hello, As I try to use X11vnc on the tinkerboard I am stuck with a default display resolution which is less than what I need. Is there any way to change the default resolution ? Thanks

Hello everybody, I just try this morning to make tinkerboard to create its own network with the networking manager. I tested hotspot and adhoc. Despite the fact that the network looks to be up (maybe yes, maybe not because in hotspot mode the icon looks like a RJ45 plug and 4 bars in adhoc) I can't connect any devices to it. Looks like handshake or authorisation doesn't work. Does anybody have met the problem and any idea to solve it. Patrick

Well I hope this come quickly on a stable distribution.

Hello all, Here is Patrick from France. I am looking for informations about this board that I want to use to astronomic applications. This board has a powerful GPU that can be use for it. The software I will use are graphic consuming. One of them, Stellarium, needs 3D acceleration to work fluently. I have the board and I have compiled the software on it. Unfortunately the armbian looks to don't have graphic acceleration. Is there versions of linux OS that can provide graphic acceleration today ? Regards Patrick
