Theoretically, a self-taught dev could get into it, if they were truly motivated and found the right opportunity, but there's not going to be a boot camp for it, at least in the West. Boot camps exist primarily because the demand for web developers outpaces the supply substantially. The same cannot be said for firmware engineers in the US. That being said, there are accelerated CS undergrad degrees out there that may help you break into the field in the fewest number of calendar months. Though at the end, there's a good chance you wind up doing web dev anyway.
