TMS320F28034: Setup CANTOS

Bernd,

Please explain "reset steadily"

I agree TRS.n is irrelevant for reception.

Have you looked at the example code in SPRA876? (It is only for transmission though)

Hareesh,

steadily mean constant reset, no change.

I have seen SPRA876b but didn't find anything regarding reception.

Regards, Bernd

Bernd,

            I believe I understand what you are saying now “reset steadily”. I think you are saying the TOS.n bit stays at zero. I have the following notes in my app.note example:

The TOS.n bit will be cleared upon (eventual) successful transmission. The only way to ascertain if a time-out occurred is to copy TOS and GIFn registers in the ISR to check if the relevant bits were set when the ISR was just entered.

I think this should apply for reception as well. Can you take a snapshot of the flags in the ISR?

Hareesh,

sent the customer the Programming Examples for the TMS320x28xx eCAN :

Thanks for the note “The only way to ascertain if a time-out occurred is to copy TOS and GIFn registers in the ISR to check if the relevant bits were set when the ISR was just entered”. Thus I will check conscientiously MOTO_A.c and its interrupt service routine eCAN0INT_ISR() …

Let me check if he succeeded.
