Original question:

TMS320F28P650DK: TMS320F28P650DK MCANB not getting out of init

TMS320F28P650DK: MCANB reception is running very slow

Tool/software:

We are performing block transfer over CAN.

Earlier we used the DCAN module and the speed was very high. We could download an image within 6 seconds.

With MCAN, we observe the speed has dropped dramatically.

Are there any caveats with using MCAN that can cause this? TX seems to be working really well.

    Hey Jayakrishnan,

    Apologies for the delayed response.

    What is the device transmitting the image?

    Can you provide additional information on your expected CAN Timing parameters (system expectations, configuration code screenshots, etc...)?

    What tests have been done to verify CAN TX is working as expected?

    Just to verify, have you reviewed the DCAN to MCAN Migration Guide?
