CAN id incorrect

I have a STM32G474 mcu that i am learning to program. I have the CANBUS tx on PA12 working by loopback mode. I have connected my logic analyzer and i receive the data correctly.

There is only one thing wrong: The ID has bit1 that keeps being set to 1. So if i would give the adress

0x200 (0b0010 0000 0000) it outputs 0b0110 0000 0000)

0x100 (0b0001 0000 0000) it outputs 0b0101 0000 0000)

 

Anyone with idea's how this is possible?

Thanks!

I have done both a loopback program and a normal mode program. Both show the same ID fault. I have created a totally new project. That one does work now without the issue.

 

Thanks all.
