pschasch Posted November 8, 2019 Share Posted November 8, 2019 Hello, I just fresh installed Armbian_5.31_Lamobo-r1_Debian_jessie_next_4.9.7.img on my R1(which is for me a fantastic device). I tried to use GPIO by sysfs like I used to do on 3.4.113-kernel. on 3.4.113: echo "17" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio17/direction cat /sys/class/gpio/gpio17/value echo "1" > /sys/class/gpio/gpio17/value gpio -g read 17 ...this is working fine ls -l /sys/class/gpio/ --w------- 1 root root 4096 Nov 4 19:17 export lrwxrwxrwx 1 root root 0 Nov 4 19:17 gpio14 -> ../../devices/platform/gpio-sunxi/gpio/gpio14 lrwxrwxrwx 1 root root 0 Nov 4 19:17 gpio15 -> ../../devices/platform/gpio-sunxi/gpio/gpio15 lrwxrwxrwx 1 root root 0 Nov 4 19:17 gpio2 -> ../../devices/platform/gpio-sunxi/gpio/gpio2 lrwxrwxrwx 1 root root 0 Nov 4 19:17 gpio22 -> ../../devices/platform/gpio-sunxi/gpio/gpio22 lrwxrwxrwx 1 root root 0 Nov 4 19:17 gpio27 -> ../../devices/platform/gpio-sunxi/gpio/gpio27 lrwxrwxrwx 1 root root 0 Nov 4 19:17 gpio3 -> ../../devices/platform/gpio-sunxi/gpio/gpio3 lrwxrwxrwx 1 root root 0 Nov 4 19:17 gpio17 -> ../../devices/platform/gpio-sunxi/gpio/gpio17 lrwxrwxrwx 1 root root 0 Nov 8 08:02 gpiochip1 -> ../../devices/platform/gpio-sunxi/gpio/gpiochip1 --w------- 1 root root 4096 Nov 8 08:02 unexport on 'Linux lamobo 4.9.7-sunxi #1 SMP Thu Feb 2 01:52:06 CET 2017 armv7l GNU/Linux' it is NOT working root@lamobo:~# echo "17" > /sys/class/gpio/export root@lamobo:~# ls -l /sys/class/gpio/ --w------- 1 root root 4096 Nov 8 08:13 export lrwxrwxrwx 1 root root 0 Nov 8 08:13 gpio17 -> ../../devices/platform/soc@01c00000/1c20800.pinctrl/gpiochip0/gpio/gpio17 lrwxrwxrwx 1 root root 0 Jan 1 1970 gpiochip0 -> ../../devices/platform/soc@01c00000/1c20800.pinctrl/gpio/gpiochip0 lrwxrwxrwx 1 root root 0 Jan 1 1970 gpiochip413 -> ../../devices/platform/soc@01c00000/1c2ac00.i2c/i2c-0/0-0034/axp20x-gpio/gpio/gpiochip413 --w------- 1 root root 4096 Jan 1 1970 unexport ...till here it is fine, but when I do echo "out" > /sys/class/gpio/gpio17/direction (or 'echo out > /sys/class/gpio/gpio17/direction' ) no function of this command / something is crashing and even the "Network/swich" is crashing, the network does not work anymore and the lights of all ethx's go on in 'dimmed'-modus on.

Tido Posted November 8, 2019 Share Posted November 8, 2019 There are 3 options to use GPIO in armbian: https://forum.armbian.com/topic/9071-opi-zero-plus-h5-and-gpio-library/?do=findComment&comment=68424 By the way, what do you control with the GPIO on R1? 1 Link to comment Share on other sites More sharing options...
pschasch Posted November 8, 2019 Author Share Posted November 8, 2019 Hi Tido, thanks for fast answer. R1 is AP and switch. - Additional I control 4 LED's to check stuff/States - 4 Inputs to controll my (smart)homeserver FHEM - set some relais... - get IR codes from remote control - PIR to react on movements near to R1 I also need to use gpio for send 433MHz codes, now based on 3.4.113 and wiringpi and rc-switch My first test with armbianIO failed: root@lamobo:~/io/ArmbianIO# ./demo 0=Le potato (Lamobo R1) 1=Banana Pi M2 Zero (not 'Lamobo R1') 2=Raspberry Pi (not 'Lamobo R1') ... 15=Tinkerboard (not 'Lamobo R1')Unrecognized board type, aborting... Problem initializing ArmbianIO library ...no "Banana Pi" no "R1", this would be compatible... I do not know if it is compatible to raspi??? But why is sysfs NOT working? echo "17" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio17/direction cat /sys/class/gpio/gpio17/value echo "1" > /sys/class/gpio/gpio17/value and why does 17 crash the switch? Why is sysfs activated in this lamobo kernel if does not work? other adresses/gpionumbers? I do not understand the problem with sysfs... Link to comment Share on other sites More sharing options...
pschasch Posted November 8, 2019 Author Share Posted November 8, 2019 OK...I am smarter now...

Are those new adresses because of kernel change? From 3 to 4 or 5 ? Why? Link to comment Share on other sites More sharing options...

pschasch Posted November 11, 2019 Author Share Posted November 11, 2019 Ok, here my result from weekend for those who are interested: armbianio needs patch for Lamobo(armbianio.patch): ------------------------------------------ ...armbianio.patch diff --git a/armbianio.c b/armbianio.c +static int iLamobor1Pins[] = {-1,-1,-1,53,-1,52,-1,259,224,-1, + 225,275,226,274,-1,273,244,-1,245,268, + -1,269,272,267,266,-1 + ,270}; ... ------------------------------------------ Sending 433-Mhz-codes now also work with WiringBPi on kernel >=4... with WiringPi it does not work. Only thing I do still not unterstand is why on PI19(275) worked with 17 on 3.4.x But, now my gpio's work like it should, if I change addresses like in io-3.x-vs-4-x.png 1 Link to comment Share on other sites More sharing options...
