How to solve the error 0x3ff6206b

i have two can ports, so i am transmitting through can0 and receiving it in the can1, but the problem is i am able to transmit up to 125kbps in the high speed bus, but above 125kps i am not able to see the response in the NI-CAN Bus Monitor, it gives me the error as canwarncommstuff or sometime it gives me canwarncommNoAck , I have also attached my error display,so what does it mean ?

Hello raj

In your test application we have this waring very often. The reason for this is that we have worng cabling connection (this is also mentioned in your Errormessage).
So plese check your cabling connection and make sure
that your CAN-card is using the interal power supply for the CAN-Transceiver IC. This is done with jumpers

Then check the termination resistors
At the both ends of bus the should be 120 Ohm resistor
from High to Low

Note High is on PIN7 and Low is on PIN2
Only for testapp. forget all other Pins

Greetings

Juergen


If this is done your app should work.

Are you sure your board isn´t a Dual Speed Board?
In this case the second port works only up to 125 KBaud. Have a look on the board whether or not the transceivers are different.
