Btw, MCU2 AFAIK also has soldered on EMMC, so still the same problem, though maybe they reduced the logging?

It is 64G vs 8G ... after many repetitive writes to a single location, the data fails to record properly so a bigger emmc means a much longer time before failure.

“The emmc chips differ by the way, MCU1 is 8GB Hynix H26M42001FMR or similar, MCU2 is 64GB Micron MTFC64GAJAECE-AIT.”

Elon just froze all the MCU1 owners with that tweet. Anyone who had thoughts of trading up for a newer MCU2 car will do nothing now and sit back until he clarifies his tweet.
Well, not sure he and Fred are on the best of terms from some tweets I saw back when. Need someone else to get him next time to try to clarify.

I really don’t think he meant get caraoke working on MCU 1....

Not to my knowledge, I think ingineer went through it in the video he did with Rich rebuilds on YouTube. Granted it was in reference to the model 3 but same same....

One would think if TSLA, is watching this forum, they would stop all the Linux logging, and keep the TSLA logging.

It could be an easy push to the MCU1 systems, I imagine.
