The Industrial Raspberry Pi Forum

Hi, we are observing solid A3 light on RevPi Connect 2019-03-14-revpi-stretch however there is nothing remarkable from running software. RevPi document says A3 is open for user and not reserved for error notification services.

Questions:
- Is there any context attached to A3 red definition out-of-the box?
- piTest -d returns no device, would any code change necessary to control A3 on this platform?

Best,
- Josh

Hi Josh, this seems strange as that LEDs are designed for personal use. So it seems to me like some process is writing to the process image at the location of the A3 LED.
Can you update the image to the latest "Buster" and try it again?

Hi Josh can you give me an update on this?
