  1. I am back to square one. I fired up the project, after I've made the script with all the pins that I needed and my project still doesn't work. I have put the following lines of code inside /etc/rc.local so that it fires up on every boot: ``` echo 362 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio362/direction echo 68 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio68/direction echo 35 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio35/direction echo 71 > /sys/class/gpio/export echo out > /sys/class/gpio/gpi
  2. It appears that I have some life in the Pins after all. How can I make them "wake-up" on every boot ?
  3. I can't use echo 101 > /sys/class/gpio/export I have a rather strange error. I am the root and I can't do a thing to export. root@bananapim3:/sys/class/gpio# ls -l total 0 --w------- 1 root root 4096 Jan 1 1970 export lrwxrwxrwx 1 root root 0 Jan 1 1970 gpiochip0 -> ../../devices/platform/soc/1c20800.pinctrl/gpio/gpiochip0 lrwxrwxrwx 1 root root 0 Jan 1 1970 gpiochip352 -> ../../devices/platform/soc/1f02c00.pinctrl/gpio/gpiochip352 lrwxrwxrwx 1 root root 0 Jun 25 09:35 gpiochip414 -> ../../devices/platform/soc/1f03400.rsb/sunxi-rsb-3a3/axp20x-gpio/gpi
  4. Hello ! I have a Banana Pi M3 that has 0 output on every pin. I measured 0 output using an oscilloscope. I have been on all of the forums I can think of and I got no answer. How can I make the pins of this damned board work like the ones from a Raspberry Pi ? How does one define a pin ? What does defining a pin means ? Because the pins look dead to me. How do I make them start ? How do I make them to output something... anything ? I am a total and complete noob and I have no idea of the kernel voodoo that has to be done. I am using ARMBIAN 5.83 sta
  5. Hello ! I’ve been trying for the past few days to make the Banana Pi M3 work with hzeller/rpi-rgb-led-matrix LED Library. But it doesn’t. I’ve tried with Jessie: Linux bpi-iot-ros-ai 3.4.39-BPI-M3-Kernel PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)" NAME="Raspbian GNU/Linux" VERSION_ID="8" VERSION="8 (jessie)" ID=raspbian ID_LIKE=debian then I’ve tried with armbian: Linux bananapim3 4.19.38-sunxi PRETTY_NAME="Debian GNU/Linux 9 (stretch)" NAME="Debian GNU/Linux" VERSION_ID="9" VERSION="9 (stretch)" ID=debian No luck. The project works perfectly fine with Raspberry
