AM335x DCAN probrem.

Hi,

Can you please describe your problem in more detail? Also please post what software and which version you are using.

Now I use Starterware 2.0.1.1.
And Tx/Rx is driven by interrupt. not use EDMA.

And use RTOS, not TI SYS/BIOS.

1.
AM335x 1 DCAN port send some frame to some slave. (Command)

2.
Am335x wait ID 0x030000 and acceptance filter 0xFF0000 (receive 0x030000 - 0x03FFFF). Use MsgObj 32.
Some slave send same ID range frame (0x030000 and 0x030001). (Responce)

3.
When period of Rx frame is so long , no problem.
When this period is too short, DCAN interrupt is not occurred.

I checked by using protocol analyzer.
Last receive frame is unmatched to DCAN register.

I can't understand, why interrupt isn't occurred.

I think this problem generated by the same cause. (linked article)



Best Regards.

Thanks.

But I think this problem doesn't occurred by starterware.

In same case, you wrote "I will bring this to the factory team's attention.".
