GPIO not work anymore on ThinkerBoard

zixzix commented 3 years ago

Initialization of any type of device on any gpio no longer works on ThinkerBoard in the latest versions of diozero. It worked perfectly up to version 0.13. In all versions of diozero, including 1.20, using the following code the board is recognized correctly. DeviceFactoryHelper.getNativeDeviceFactory().getBoardInfo();

If i use the lasted version of library with the following code

new DigitalOutputDevice(pin, true, false);

it goes into error and I get the following message:

java.lang.IllegalArgumentException: Can't find chip for id 5
        at com.diozero.internal.provider.builtin.DefaultDeviceFactory.createDigitalOutputDevice(DefaultDeviceFactory.java:256)
        at com.diozero.internal.spi.GpioDeviceFactoryInterface.provisionDigitalOutputDevice(GpioDeviceFactoryInterface.java:84)

....

Maybe there is some problem with the gpio mapping? Thank you

with "sudo gpiodetect" i get a command not found so I have tried with sudo java -cp diozero-sampleapps-1.2.0.jar com.diozero.sampleapps.GpioDetect

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "java.util.List.forEach(java.util.function.Consumer)" because the return value of "com.diozero.internal.provider.builtin.gpio.GpioChip.getChips()" is null

Try run with -Ddiozero.gpio.chardev=false. Hopefully that will get rid of those errors. Have a think about trying Armbian as it uses a much newer kernel and is actively supported.

Thank you!! Seems to work fine, I will do more tests asap 👍
