failed to open gpio

[kanr]

Trying to debug an issue with raspberry pi, docker(balena) container, gpio access.

Specifically I am working with the opensprinkler, v1.4.3

In the opensprinkler gpio.cpp module there is a gpio function that I believe is failing (see log files bellow). I have edited the logs for clarity but in the full output you would see ....(-0800) failed to open gpio running ad infinitum (again and again).

I made sure cap_add: - SYS_RAWIO is in my docker-compose file, are there any other suggestions for how the OpenSprinkler compiled firmware access to GPIO from within the (balena) container?
