CAB BUS Mismatch inside FCAN_Config Block and FCAN_Send and FCAN_Receive Block (MPC5748 Series)

youngkugpark — Fri, 11 Sep 2020 04:02:21 GMT

Eight CAN BUSs are available for MPC5748G on FCAN_Config Block, but only 0-2 (3 Bus) can be selected on CAN Send and CAN Receive Block.
Is this a bug in the MBDT? Or is there another reason?

Hello @youngkugpark ,

Thank you for noticing this behavior. Indeed there is a bug there not displaying all of the CAN instances on some of the blocks.

Make sure you are using our latest MPC57xx 3.2.0 version by typing the 'ver' command under Matlab. The output should contain the following line:

Model-Based Design Toolbox for MPC57xx Series Version 3.2.0 (R2016a-R2020a)

Please backup first and then replace the mbd_mpc574x_ec_toolbox.mdl file under {Toolbox addons install path}\src\mbdtbx_mpc574x\mbdtbx_mpc574x and reply if this solved the issue.

Hope this helps,

Marius

Thank you for your quick response.
As you said, I have corrected it and checked it and confirmed that it can be set and compiled normally.
I will check if it works properly on the development board next Monday.
Thank you.
