Log Handling Subsystem

[ztnel]

Description

We need to implement a logging solution to aid in debugging as well as track the state of the firmware in production. Logging will be performed through a UDP configured socket. In the case that the system is offline (offline detection required), logs will be sent over SPI to the SD card. The logging subsystem will be provisioned a single socket for logging.

The production systems will be a logging client streaming logs to a log aggregator such as Loki. Debug releases will have a socket server which can be connected to in order to view the active logs:
