Ask HN: How to do continuous integration / delivery of embedded software?

I am an embedded software engineer working for a company which does warehouse automation using autonomous mobile robots.

Though the high level stack is in Erlang, most of the software I write is on C for ARM, AVR and MSP430. These are bare metal codes(no Linux/RTOS layer) which implement anything from a basic driver to complex algorithms. How to make a simple continuous build or delivery system for such software?
