Followed this site
but unable to blink a single LED on my banana pi m4
It gives the following error
No access to /dev/mem. Try running as root!
Tried with sudo and sudo su -i too.
And there is no official documentation as well
Can anybody tell us how to do
Thanks in advance
Very disappointed to see there is absolutely no support for GPIO!!
There is no support for anything.
List of problems
1-SD card doesn’t get detected after booting from emmc
2-Above GPIO issue
3-Internal WIFI chip is literally a joke, have to keep a hotspot device next to it to get connectivity.
4-have 64GB sd card but only 8GB get recognized and we are left with around 800MB of storage.
