CAN communication between TMS570LS31x HDK board and TMS570LS04x/03x HDK board cannot be established

Other Parts Discussed in Thread: HALCOGEN

Hello,

We have been using your TMS570LS31x HDK for a while. We established CAN communication between two these boards using C code obtained from HALCoGen v3.03.01 software and it works fine.

Recently we bought TMS570LS04x/03x HDK and we tried to establish CAN communication between one TMS570LS31x HDK board and one TMS570LS04x/03x HDK board, but we did not succeed. We tried with both standard and extended identifier. I should also mention that we established CAN communication between CAN1 and CAN2 port on the TMS570LS04x/03x HDK board.

What can be source of this issue?

Best regards,

Marko Nikolic

Hello John,

Thank you for your fast response.

Today we discovered that clocks on TMS570LS04x/03x HDK don't have expected values, and that was the reason why CAN communication could not be established with other board (bit rates were different).

I think this issue is solved now.

Thank you once again.

Best regards,
