I've compiled application on Linux, but I got this error
wiringPiSetup: mmap (GPIO) failed: Operation not permitted
iomem=relaxed to grub
cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-4.15.0-88-generic root=UUID=da37e191-361e-4343-a63b-980e2696c8d6 ro iomem=relaxed console=tty1 console=ttyS0
But It didn't help. How I can fix this issue?
