Hi everybody,
I am currently working on a testcase for a CAN microcontroller. The microcontroller is connected to a CAN analyzer (Vector Canalyzer pro).
Microcontroller: TC1766.
There are only two node (NODE0, NODE1) on the microcontroller and I want to send frames and see if they are displayed on the analyzer. All the frames sent by NODE0 are successfully transmitted and can be seen on the analyzer. The test is OK at this point.
Unfortunately when it comes to NODE1, the first frames is never sent, i get this error:
- Bit0 Error: During transmission, node tried to send a dominant level, but monitored value was recessive.
Nothing appears on the oscilloscope ( but i could see the frames for NODE0). I checked all the registers involved and i didn t see any issue (no obvious issue at least)
Have you already got this error ? Do you know what it can means precisely ?
If you Could you help me or at least give me a hint on where to look at, that would be great . I ve been looking for this problem for two weeks now, i m out of solutions...
Thanks
