Are you going to contribute a Gerber file to the project? What chips did you use? Looks like you are drawing power from Vusb. In the current schematic that is listed as an unknown. Can you confirm Vusb has significant power to run the assembly? for CAN I use max3051 (3.3V), powered direct from teen...

I have a little present for you all if it is helpful, It can be used with Dice for individual module programming as long as you have 3 items. 1) pin code 2) SBL (secondary boot loader) 3) the file you wish to flash. This is the latest version used from P80 Chassis types all the way to the new SPA/C...

Not my first bootloader, this is even able to read and write external EEPROM of the CPU, but i think most people want a config changer here and i hope to get it work this easter days... Who just needs a dice flash reading tool can pm me to read out his complete CEM flash when he got code by teensy b...

Yeah, I'm sorry, my free time has evaporated recently. Everyone is welcome to tweak the code and submit improvements, it is opensource.

Heard it before and know this could maybee be written some where in the thread, but what is the main problem to crack the code on early P2? Is it not that type of bug on that MCU/soft? K.line only needs sending "keepalive" to get to the canbus, or from "inside canbus" instead? K...

Sorry was 50 downloads only, here are both again...

Also Windows 10 doesn't notice me about anything, maybe it is location based on 3 computers i get nothing. Maybe defender in US sees something problematic in this code...

This reads flash by 6 byte code:

This works on all CEMs to MY 2004, 10th place of VIN Y, 1, 2, 3 or 4. Read cem by arduino once, place it back into car and change how often you like by dice. screenshot.2 CEM tool.jpg Read CEM by arduino nano or UNO by this: #define BKPT 4 #define RESET 5 #define FREEZE 6 #define DSI 7 #define DSO 8...

CEM Data Manager.jpg I made this long ago for my self. It works, for me and i hope for anyone who needs it to copy his own CEM. For just changing config, better take the other tool and write only the config to your cem by dice... https://www.matthewsvolvosite.com/forums/viewtopic.php?t=85611&st...

I know this isn't specific to XC90, but considering the popular CEM swapping thread and the technical discussions and hacking over there I decided to create this thread. The other forum sections are less popular. If Matthew of course allows this thread to remain here or if he wishes, he could move i...
