Anybody have ISP pinout for IC tegra?
Hello, does someone has an mmc pinout from IC Tegra board? I have bricked IC after sw update... Thanks
They mean a diagram of points on the board to read/write the eMMC without removal. Not a generic pinout of the chip.

Here you go, if this is what you meant by mmc pinout:"
Yes exactly. Thanks
Instrument cluster is different than CIDHere you go, if this is what you meant by mmc pinout:
Preventive eMMC replacement on MCU1
Just had the MCU2 upgrade done to 2014 Dec issue S85 as after may visits and calls regarding MCU1 failing issues I just thought that I would like my heating to work, internet connection to come back on and the car to stop rebooting if I looked at it the wrong way. Very happy with the screen...teslamotorsclub.com
I read IC Tegra and assumed Integrated Circuit, meaning the Tegra board from the CID. Oups!Instrument cluster is different than CID
They are not encrypted... you'd need the car.crt and car.key pair. If you have these two files, I can verify them for you.Can someone help me to restore my certificates and keys from the IC firmware. I have already have the dump, but it seems that the keys and certs are 'encrypted' maybe?
They seems they are not in the p3, i think they are in the RAM and when the IC is powered up, they are placed in the p3 filesystem.They are not encrypted... you'd need the car.crt and car.key pair. If you have these two files, I can verify them for you.
How are you reading the ram?They seems they are not in the p3, i think they are in the RAM and when the IC is powered up, they are placed in the p3 filesystem.
We have read the firmware with ISP, which seems to be mismatched it. If you know where are car.crt and car.key in the RAM, it will be helpful.
The key you found is for RSA testing. This is not the key to your car. Below is the key you found and the matching certificate for your information. You can google parts of it and find this RSA pair used quite a bit.Can someone help me to restore my certificates and keys from the IC firmware.

you won't find them in the IC dump... at least not on firmware recent enough where the keys would still be valid. The certs expire after 2years if not renewed and firmware old enough to keep keys on the IC would be too old to be renewing. They don't exist on the IC at all.In my case the eMMC from the CID is dead and i`m unable to restore the keys from it. The only option is to find them in the IC dump, as someone in the thread mention that they are also there. Is it possible to fin them in IC dump?
At the end the eMMC chip was physically damaged (don ask me why ) .

You can mail me the dead eMMC from the CID or the Tegra board if the eMMC is still mounted. I've been reasonably successful at recovering them.
I'd only charge anything if I was successful in recovering the certs.
None that I'm aware of.At the end the eMMC chip was physically damaged (don ask me why ) . So is there any other option to restore the keys?
The car is not running at the moment, as the eMMC of CID MCU needs to be replaced, once we have solution for the keys. In the dump of the IC we found only mismatched certs/keys and we are not sure how to proceed with the dump. Currently the only option is to load latest firmware and hope that the car is running, at least. Than maybe we will try to contact Tesla service center in Romania, as here in Bulgaria we don't have one . Any ideas will be greatly appreciated.None that I'm aware of.
I've been working on a 3rd-party web-based app replacement for CIDs running older firmware (2020.36 and earlier) for vehicles that for whatever reason no longer have valid keys.
What firmware are you running? or is the vehicle even running at this point?
Alternative would be to somehow get Tesla to generate and install a new set of keys. I'm very interested in knowing what the process is to make this happen. There must be a procedure to have a new SSL cert/key installed by Tesla. They would need to do this when performing the eMMC 8gb to 64gb tegra replacement. I'm sure it would require physically bringing the vehicle into a service center, but if I brought my car in asking for new SSL keys, I have the feeling they'd just look at me funny and say "what???"
In the event you've never had the 8gb recall done... just bring it in for that and your missing key issue should be resolved in the process.
