Well, you might still need flaws to be fixed in the device, but now flaws in the device can never be corrected.
- Gracana 4y agoIn the past, technicians would get engineering change orders and follow the instructions to rewire boards to fix problems. You could also replace state machine and microprogram ROMs, which I guess sounds a lot like a firmware update.
- ReactiveJelly 4y agoIt's expensive to hire someone technical enough to: - Perform such an update - Sign off that they performed the update _correctly_ If you need an air-gapped system, it's still much easier to set it up so it can update from a USB flash drive and log "I did the update correctly" back to the drive.

- bluGill 4y agotrue, but most people doing hardware are doing formal designs and prove their work correct. While the proofs are not perfect, there are a lot less bugs. The cost of fixing bugs in hardware is a lot more than software, so it is seen as worth it. Of course the cost of doing the above is one reason we don't do everything in hardware. If you have the money you could implement everything people do with computers in hardware, no software - I don't even want to think about the cost.
- heurisko 4y agoI have experience working with IoT hardware, there were a fair few bugs, in an apparently constrained domain. One including a datatype mismatch, that was also a bug in the specification.
