Firmware is nothing but program instructions for a device that is stored in memory and set up a device to run. Firmware for devices are regularly updated, including phones and cameras and the like.
I'm not really going to argue this. That's just how it is. I've made my living writing software for a long time now and have updated firmware on tons of devices over the decades, though for some devices there's never an update or need for one. With a device like the evic (or any of my dSLRs for example) I would expect the firmware to be easily updated and occasionally so. If it's not, shame on them. There's no reason for it to be a challenge at all though. Typically on a device like a camera (or assumption an evic) there's storage for the original firmware and that will never be overwritten. However, that is not where the executed firmware resides. There's another storage for that, and that is what is updated when a firmware update occurs. Resetting to factory defaults just loads the original firmware (remember it was never overwritten) back to that spot. It's not rocket science and is pretty standard these days. Also, there's no program code on a chip. I'd expect the evic's firmware to be easily updateable and no different from a software patch because on a device like an evic I would be 99.9999% confident (and this is how dslr's work) the firmware is the only software being run.
Agreed with everything until you said there's no code on a chip. That's incorrect. All embedded and binary level data is stored on chips ... and that goes for ALL electronics.
I will guarantee you the eVic has an EPROM which stores all operating code (like every other digital pv). An EPROM is a chip.
I mean, if someone really wanted to ... they could remove the EPROM from their pv ... connect it to an EPROM reader/writer and change the embedded code themselves. So say you had a device which had an amp limit in the software, you could increase that limit beyond what the manufacturer set it to on your own. In fact, many amp limitations ARE in the software. Kinda surprised no one has really started hacking their pvs hardcore honestly.
