At the rate they were rushing to design and build that hardware. I'm absolutely not surprised they chose not to go through the extra steps of qualifying a connector/mount for a flash daughtercard. It's very likely the hardware designers didn't expect the software living on that flash to iterate that many times. In too many ways, Tesla was and still is a hardware startup.

Every write up I've seen indicates the amount of stuff being put into /var is inappropriate for flash, beyond that, those logs should be kept in RAM until shutdown then you commit them to disk. I'd have no issue with this stuff bricking if Tesla replaced it free (even more galling that they won't on a 50k+ vehicle), you'll have a hard time convincing anyone that a ECU should last less than a decade under normal operation, Nor should you need to replace the ECU before you replace the battery pack on an electric car. If storage space was alone an issue, then they shouldn't have extended the features of those firmware loads so much - as far as I know the owner has no choice on if you update or not.

  Owner absolutely has control over installation of firmware updates.

    I wonder how many dealers do updates without your notice/consent when you bring the car in for repair/warranty/recall work. They probably plug in their dongle for diagnostics and hit « yes » if it prompts them for an update.

> chose not to go through the extra steps of qualifying a connector/mount for a flash daughtercard are there such connectors suitable for automotive environments ? you don't want your flash to fall off while driving

  Yes, absolutely. The automotive electronics industry has been going strong for decades and has a well-established library of components. Finding (or customizing) the right one is the hard part...
