Part Number: AWR1642BOOST

Tool/software: TI-RTOS

Hi Team,
I tested lab0005_object_data_over_can on AWR1642BOOST.
I refer to ObjectDataOverCAN_GettingStartedGuide.pdfto set up my test environment.
Connect the PCAN-USBFD CAN lines to AWR1642BOOST.

The demo is working fine, but there are some error.

Hi Will,

Did you change any timing parameter in the default application?

Hsu,

When any CAN message transmission/reception fails, controller updates LEC(Last Error Code) and DLEC(Data Phase Last Error Code) fields in status register('MCAN_PSR' ).

LEC: this field is updated when error happened in arbitration phase in case of CAN FD message or during full message for classic CAN message.
DLEC: this field is updated when error happened in data phase in case of CAN FD message.

Could you provide the LEC/DLEC fields when the stuff error is seen?

Stuff Error is caused if more than 5 equal bits in a sequence have occurred in a part of a received message where this is not allowed. Do you have receive messages also coming in?

Thanks,

Raghu
