Hello guys,
I'm trying actually to use the Multican+ in order to send/receive messages with an external CAN Analyzer (CAN Vector) from the CAN Node 0. I used the sample code for the TC275 Lite Kit,
configure the input/output P20.7 as a pull-up input and P20.8 as a push-pull output + disable the loopback Mode.
I check also the hardware configuration, the physical connection seems good (120 Ohms termination resistor end-to-end of the bus), the baudrate and the sample point (75%) are the same for the Aurix and the CAN Vector.
When I look closely at the registers, when requesting transmission (set TXRQ) :
NEWDAT = 0 (cleared by hardware meaning that the data has been transferred to the internal buffer of the CAN Node + indicate that the msg is no longer new)
TXPND = 0 (NO CAN message has been transmitted)
TXRQ = 1 (not cleared by hardware meaning that transmission is not successful)
If we take a look at the Node Status Register, this is what we see :
Last Error Code = 5 (LEC, meaning A CAN Error Bit 1 ; the CAN Node tried to send a dominant level but the monitored bus value was recessive)
TXOK = 0 (transmission not successful)
ALERT = 1 (Alert Warning)
Bus-Off Status = 0
The signal INIT goes back to 1, meaning that the node is not participating anymore in the CAN traffic.
Do you have an idea of the potential problem ? What do you suggest please ?
Thank you,
