B4J Question jpi4j2 library with non RPI CPU

[EvgenyB4A]

Does jpi4j2 library work with non RPI CPUs under Debian Linux distribution?
Foe example RK3288 CPU.

The supported boards: https://pi4j.com/documentation/java-installation/

 

[EvgenyB4A]

I try to use this library with RK3566 chip and get errors at these lines:

131 pi4j.Initialize("pi4j")
132 PinOut.Initialize(pi4j, 3) '18 BCM addresses: https://pi4j.com/documentation/pin-numbering/

The logs:

[Erel]

It is probably not supported. Are you running b4j-bridge with sudo?

 

[EvgenyB4A]

Yes. with sudo

 

[EvgenyB4A]

Are there other GPIO libraries?

 

[Erel]

No. You might be able to do something with jShell and running the OS programs that control the IO pins.
