Making Magic Leap past Nvidia's secure bootchain and breaking Tesla Autopilots

[einsteinx2]

> The Tegra X2 is an SoC used in devices such as the Magic Leap One, and Tesla's Autopilot 2 & 2.5 promising a secure bootchain.

I guess they didn’t learn from the Tegra X1 which was famously responsible for the boot rom exploit on the original model of the Nintendo Switch.

Here’s the video of the talk. Not sure why the schedule page was linked.

Huh, I thought Magic Leap went out of business.

Didn't know they were still around!

Unfortunately they are. They're a former shell of what they were. I think they're changing their focus to lenses or something. Last I heard they're partnering with Google and it's absolute ass. The company is effectively dead and being carved out for parts by Google is my take.

It's a real bummer because they were the only company I was actually interested in seeing pursue Augmented Reality. Now it's literally the most evil companies Meta, Google, and Apple.

The 90s optimism of future tech is dead and all that's left is whatever this is.

Just curious, how fast can these embedded systems boot?

[saidinesh5]

It really depends on the application.

With the similar/even weaker socs (imx6 etc..), in the automotive domain, we used to target sub 5 second latency.. we had to get rid of things like even init and directly start the application..

Eg: 1.5 seconds here: https://youtu.be/QbEYhQIjlQc

There's a popular slide deck[1] with common techniques for paring it back too.

I hope Nvidia's new offerings (Orin, Thor, etc) don't have the same issue in their bootROM. That would be an incredibly expensive mistake.

[userbinator]

I hope they do, for those who want actual ownership of what they bought.

Sounds really interesting. CCC is an amazing event.
