WiringPi 2.50 (already patched for generic debian)

WiringPi for Linux

Compatible with: Unosquare.Raspberry.IO 0.17.2

Actions to do in order to compile WiringPi

Disable Kernel strict security

1. Open with nano or through GUI file: /boot/firmware/cmdline.txt

2. Add following string at the end: iomem=relaxed

3. Final result should look like that:

4. console=tty0 console=ttyS1,115200 root=/dev/mmcblk0p2 rw fsck.repair=yes net.ifnames=0 cma=64M rootwait iomem=relaxed
   

5. Reboot to take effect (this steps are valid also for PiGPIO)

Compiling WiringPi

https://github.com/WiringPi/WiringPi/tree/final_official_2.50 https://github.com/sakaki-/genpi64-overlay/tree/master/dev-embedded/wiringpi/files

1. Clone 2.50 repo

2. #depth 1 in order to avoid downloading commits history
   git clone --depth 1 --branch final_official_2.50 https://github.com/WiringPi/WiringPi.git

3. Download also 2.44-pseudo-cpuinfo.patch from second link (name is not important)

4. Paste downloaded .patch file into cloned directory

5. patch -u < 2.44-pseudo-cpuinfo.patch

6. ./build

7. Test all works (you should see a table if all ok):

8. gpio readall

9. Already patched GPIO version will be packed in Parko/Distrib/Utilities_Software/RaspberryPi

10. #if wiringpi tells you have nothing in /etc/wiringpi/cpuinfo
    sudo mkdir /etc/wiringpi
    sudo cp /proc/cpuinfo /etc/wiringpi/cpuinfo

11. Making compiled WiringPi usable by C# actual unosquare.wiringPi

12. sudo ln -s /usr/local/lib/libwiringPi.so.2.50 /usr/lib/liblibwiringPi.so.2.50
