Interesting. If I understand the situation correctly, the AM/FM tuner (tuner0) has an analog output that goes into an analog input in MCU1. Whereas the new FM only tuner (tuner1) (+/- XM radio) has a digital output. Is the digital stream from tuner1 on a separate bus or on the in car...

There are hundreds of open source projects that function perfectly well. There is no reason why an open source Tesla MCU project couldn't be very productive. There might be forks. So be it. From what I've seen of the Tesla MCU software, it wouldn't take much to beat it. For starters, open...

I disagree with a a lot of what you say here.

Can you imagine the car that Tesla would have if they open sourced the console UI and gave out root to the MCU OS ? There would be so many developers working on it your head would spin. There could be several different flavors of the console UI, apps, etc. It would be fantastic. Tesla would...

What is the electrical interface between the center display and the Visual Compute Module (VCM) ? - HDMI ? - proprietary ? - LVDS ?

Also this: Tesla, Inc. Is this all the open source code they use ? The commits seem pretty recent.

It appears as though Tesla is using at least some GPL'd software in their vehicles. The Linux kernel, for starters. The GPL requires that anyone who uses code covered by the GPL release the changes or enhancements they've made to the code to the users who purchased the product that uses the...

Agreed, what is your point ? What has become of this ? Tesla ships a million cars and ignores their GPL responsibilities ? How does that work ? See here: How do we force Tesla to publish their changes to GPL code ?

From a risk point of view, if I understand the situation, when the MCU fails, Tesla replaces it. And unless you replace the existing eMMC with a new one, there is no other solution. So it is either try to replace it and maybe fail OR let it fail and Tesla will replace it for you and charge...

Depends what is being written to /var. If it is just diagnostics info, probably a lot of that can be turned off if you have access to the OS. On the machine I'm using right now, (Fedora 32) the top level /var directory looks like this: ls /var account cache db ftp kerberos local...

What do you mean by "there is nothing that Tesla wont restore with a new mcu." ? There is possibly another entire way to fix this problem, if you have enough access to the Linux system and by that I mean the boot loader. In Linux you can set up the boot loader to put (locate) different parts...

Can I have your old MCU ?

I don't see a lot of risk in attempting to fix a failed ECU. Soldering the eMMC would be about it. Copying the data off the old eMMC to the new one shouldn't be a big issue. Caveat: I've been a Linux tech since 2002.

Tesla starts to release its cars' open-source Linux software code | ZDNet

I'm not sure what the problem would be. Seems like Tesla uses Linux and the Linux kernel is worked on by thousands of people around the world. It is the largest software project in the world, run on more devices than anything else. It has proven to be very secure.
