BUS HEAVY error on MPC5200B mscan

Gopal — Tue, 05 Jun 2007 16:27:53 GMT

Hi,
I am getting BUS HEAVY error and not able to communicate to externel device.
drivername= peak-can-linux driver came with ltib.

I tried with fallowing ways.

1. can1 to can2 with baudrate 250k
this one able to send data to other port with out any problem

2. can1 to externel device with baudrate 250k.(externel device also set to 250k)
this one giving me BUS HEAVY

3.externel device with PEAK CAN VIEW sofware with baudrate 250k
this one able to send data to other port with out any problem.

can connector was properly terminated with 120k resistor.

only 2nd case giving me problem.
I am thinking this as only baudrate problem.
what should be the value for baudrate?
is there any other possible problem.

URGEN. PLEASE SEND ME REPLY AS SOON AS POSSIBLE.
regards,
venu.

Hello Venu,

For URGENT and problem blocking project developpment, we advise to use the Service Request.
The MPC5200 is partially supported via the Forums (this board is not FSL supported).

You can have help from the Community of experts here, but need to enter a Service Request to ask Freescale. Click on the link in my signature.

To speed up the process, give AS MANY INFO as you have.

The Termination is NOT 120kΩ as you wrote but 120Ω, that is a reason for failure on High Speed CAN !

Regards,
Alban.
