Firmware for canbus boxes

canbox's Issues

Original Firmware Volvo OD 02

I have successfully hacked and extracted the original firmware from the Volvo od 02, sw:5. I have extracted it, flashed it into a oem stm32f103 and works as it did with the original mcu. i open this issue so you can add it to this repo in case anyone wants to revert back.
The firmware was extracted using this method: https://github.com/JohannesObermaier/f103-analysis/tree/master/h3\
The extracted firmware here (feel free to add the file to your own repo, that way its harder to loose it): https://github.com/jesusvallejo/VolvoCanBusFirmware/blob/main/README.md

Unable to flash canbus box

I've got 2 boxes that are slightly different, 1 flashes fine, this one however refuses, seems as though it's not even seen by the flasher

Just wondering if there is something obvious I am missing or maybe this is just a different design that cannot be flashed?

How do you find out about the protocol to talk to the head unit?

I'm wondering how you figured out the different protocols that the head unit understands.

Which MCU handler did you pick on your head unit?

Building firmware for XC90

I am new to this so I apologize in advance

I would like to build the firmware for a volvo_od2 for use in an XC90

I assume to function I only need to update addresses of my modules at the end of canbox/cars/xc90_2007my.c?

What confuses me the most is how do I find all the addresses of my modules to be able to do this?

I really hope you can...

Edit: Also link to Virtual machine (https://drive.google.com/file/d/1XCHW03gKX6WUB6tFS7kKD0kZkctj8inW/view?usp=sharing) is down I cannot download...

Unable to get to configuration

So I've been playing with this some time and finally got my ST-Link to work and have flashed volvo_od2.bin to my canbus box. I have verified it has flashed. However the box does not function in the car and I have tried to connect TX/RX to pc using putty but I am just getting some scrambled messages which stop after a few lines at baud 9600. How can I troubleshoot? Is baud rate for putty 9600? Hope you can help point me in the right direction...

Where to find more serial payloads raise mqb/pq

Hi, after some time digging in your code and drive2.ru post, i cannot find where did you get the payloads for the canbox_cont and canbox_mici functions. Those codes 0x09 and 0x0c are not in the github.com/runmousefly/Wo…n_Golf7_Protocol.java# L23 link. Im adding the behind steering wheel buttons ( navi buttons ) and id like to use them to navigate through the radio, up, down, left , right , enter and back. I have allready developed everything but the canbox.c funtions that send the uart payload. Do you know if the protocol has those functions or where could i look?

Also, is there by any chance a long click could be developed so the radio is muted if for example the next button is long pressed?

Thank you very much!!
