With modemmanager you get a lot of nice stuff for "free", like automatic reconnect, DHCP, good logging, and an APN database (useful if you don't provide your own SIMs). It also allows you to easily set up correct priorities b

Have you experimented with modemmanager/networkmanager to handle the configuration of the modem? For me that has worked quite reliably across a pretty large fleet of devices with a Quectel EG25 (qmi over usb). Regarding FW updates, hav

In this case the EPS already came stock with the functionality to request torque over CAN, that part of the code or the amount of torque was not touched. I agree it would not be a good idea to patch that functionality into an EPS that doesn

Ghidra uses an intermediate language called p-code. When defining the CPU opcodes (and how to parse them), you also write a small snippet of p-code that represent that instruction. This makes the decompiler architecture agnostic. Example:

The XOR encryption was just for the update container. Newer update files usually employ some stronger forms of compression/encryption. However, it's usually some strange in-house crypto, so eventually people figure it out. bri3d r

At some point the values have no deeper meaning and are just whatever VW decided on as their API. DBC files have concepts of enums, but that’s really diminishing returns and wouldn’t make the code that much easier to understand. Also someti

See my other comment about Ford code being reference only. Supported cars have most signals defined in a dbc file, the mapping from name to id and bytes. See https://github.com/commaai/opendbc This results in much clea

The file you referenced is related to Ford, which is not a supported car/brand. The code for Ford is provided as a reference and is forced into “read-only” both by openpilot and panda (the bridge between openpilot and the car).

Do you have any guess on when premium processing would be brought back?

Seems like the https://www.vector.com/int/en/products/products-a-z/hardware... has some similar functionality. I have never used it, but by reading the documentation I'm not sure if it would have be

It might have not been clear from my comment, but I was specifically referring to those ML as a service. The TPUs seem to fall under GCP which has a less restrictive ToS. I do understand they don’t want to make it too easy to resell their r

I wonder if they will apply the same terms of service as with their Cloud Machine Learning offerings (Auto ML, Cloud Vision, etc). A snippet from https://cloud.google.com/terms/service-terms#12-google-cloud... : Cus

There is a microcontroller between the phone and the car that monitors all communication and enforces safety limits. This code is written in C++.

Can you buy them for $199 in quantity? A phone is actually a very nice and reliable piece of hardware. It has everything you need CPU, GPU, DSP, two cameras (front and back), a backup battery, a screen and wifi/lte to upload your data.

You are probably referring to fish shell which has this feature ( https://fishshell.com/ ). However, I find that zsh + ohmyzsh works just as well. After typing the beginning of a command you can use the arrow keys to cycle th

The depth output of our vision stack is currently not accurate enough to reliably measure relative speed. However our ML team is currently working on new models. Maybe in the future this will be accurate enough to do this without a radar.

The chffr team is now mostly working on improving the dashcam experience. The grey panda is a panda where we replaced the wifi chip by a high precision ublox GPS module. We can use this to make high precision maps, and in the future this wi

The exact same can be said about human drivers. Why do we demand that autonomous driving is 100% safe? I would be completely fine with autonomous cars that sometimes crash, but are still less likely to do so than with human drivers.
