"Be sure to reseat all those connections… extra attention to the connection at the Comma device (C2, etc.) as well, since that USB-C fit can be TIGHT! Many strange symptoms (eg. won't switch to ONROAD mode, empty carFw leading to unrecognized vehicle, etc.) can be attributed to USB-C connection issues.

C3x should only be flashed w/ OP 0.9.4 or higher.

Note: C3 GA was @ 0.8.7, but the 32GB version (has no NVMe drive) requires features added after 0.8.12... and the newest C3's have a different fan, which requires code that came in @ 0.8.16...
https://blog.comma.ai/0816release/#improved-fan-control / https://github.com/commaai/panda/pull/1022

There was also a newer display/screen too, so it's best to stick w/ newer code.

C2, as it is officially only supported up to 0.8.13.1

OP3T-based OG EONs are limited to 0.8.2 (can’t run 0.8.3’s NEOS 16)...

If you're trying to get to stock master-ci, you can utilize this custom URL after rebooting from a factory reset (or uninstalled OP)...
installer.comma.ai/commaai/master-ci
[can be edited to install any /]
…instead of openpilot.comma.ai

Another way is to grab the nightly...
openpilot-nightly.comma.ai

See <#538741329799413760> for old h/w on newer code.

Problems installing OP on your C2 still? An old fork w/ old NEOS, etc. may be to blame, so try...

...then uninstall. Finally, install using…

This is why we do not include a USB A to USB C to use inside the house, and provide an active SIM (for domestic orders only) so that you don't need wifi. We also do a few other things on the device to get install times down to a few minutes, even on the slow data SIM."

"Community Features - There are modifications (hardware and software) people do that Comma doesn't necessarily accept liability for. When you enable the feature, you're basically accepting liability. What's considered a "community feature" is actually defined in code. See below...

CAN-based fingerprinting moved behind community features toggle
Fuzzy car identification, enabled with Community Features toggle
Move GM port, Toyota with DSU removed, comma pedal in community features; toggle switch required

Some features or cars are marked as community features. If openpilot detects the use of a community feature it switches to dashcam mode
"Enable Community Features in Settings to Engage"

Community Maintained Cars and Features are not verified by comma to meet our [safety model](SAFETY.md). Be extra cautious using them. They are only available after enabling the toggle in `Settings->Developer->Enable Community Features`.

"Use features, such as community supported hardware, from the open source community that are not maintained or supported by comma.ai and have not been confirmed to meet the standard safety model. Be extra cautious when using these features",

intercepting the DSU is a community feature since it requires unofficial hardware

"Thank you, @vanillagorillaa and @PacHy Chris, I am running OpenPilot v0.6.1 on one of my EONs now, without the blank screen issue.

I worked around the git issue (fatal: no upstream configured for branch 'v0.6.1') simply by removing the code in openpilot/launch_chffrplus.sh that applies git updates. Now I should be able to revert back to the version I want, when I suspect regressions. I'll do some driving and see if 0.6.1 is really better than 0.6.2 when it comes to the handling of exit and widening lanes. (Maybe not.)

The most valuable part of this exercise for me was discovering the root cause using "tmux a", as well as learning about Git in more depth."

"To get the can-utils utilities working on a white Panda device:

• Download and compile all the can-utils stuff on GitHub.
• Install the Panda.ko driver by following the rules in openPilot/panda/driver/linux/README.md
• set the linux udev rules for the panda usb connection. In Panda wiki
• Plug in Panda to OBD
• start up the car
• connect the usb cable to your laptop
• lsusb should see something like: Bus 001 Device 004: ID bbaa:ddcc
• You should flash your panda at least once before you use it. see Panda Flashing wiki. I used the curl method.
• dmesg | grep -i panda should show:
◦ usb 1-2: Product: panda
◦ panda 1-2:1.0: Comma.ai Panda CAN controller connected
◦ usbcore: registered new interface driver panda
• sudo ifconfig can0 up
• go to the candump directory
• ./candump can0
• There is a similar tool in openPilot/panda/examples called can_logger.py. I was never able to get that to work via USB, but I was able to get it to work with WiFi, but it takes a bit of effort. Sometimes I see multiple Panda WiFi connections available in my wireless connections list. They all come from the same Panda device, but depending on which one I connect to, I cannot get can_logger to work. I see the same thing with chffr. When you can get chffr to connect, and run the battery test from within chffr, then you should be able to connect your laptop to connect to the panda device, and run can_logger to connect via WiFi."
