TCAN334G: 5 Mbps communication failed

Part Number: TCAN334G

Tool/software:

Hello. This is seungwook han in korea.

now, We are using 3 TCAN334G with MCU and did CAN data rates test.

we successed 1~4 Mbps test, but we failed 5Mbps test.

because we are using 3 TACN334G, we tested loop-back. So, the line length is very short.

I'm HW enginner. So, I don't know exact SW set-up.

So, is there any idea for 5Mbps improvement? in HW, SW?

Seungwook,

Can you please share waveforms of the CAN communication at 5Mbps?

Dear. Eric Hackett.

Now, we failed 5Mbps communication. So, we don't measure the wareforms.

could you share the check points of SW, firstly?

Thanks.

Seungwook,

What you are testing sounds okay, but there is not a lot of detail, so I cannot directly comment on the procedure. The best way to debug these kinds of communication issues in CAN is to see the CAN bus waveforms. So if the waveforms can be captured in anyway, please share.

Also note that starting today, US holidays are happening, so please expect delays in response. We will be back in office on 07/08/2024.

Regards,

Eric Hackett
