AWR1843BOOST: I want to get CAN Data (DCAN) using AWR1843BOOST

Vinoth Kumar C

Part Number: AWR1843BOOST

Tool/software:

I want to take Normal CAN Data (DCAN) from AWR1843BOOST (I do not need FD-CAN). I have made the CAN initilaisation as per the document referenced below,

www.ti.com/.../spracg9.pdf

I have selected the following signals as part of CAN initialisation. My question is whether i can get the CAN data from the AWR1843BOOST CAN Interface connector using the below PINs initialised.

Please provide the Correct pin configraution, if this is not correct.
I have taken the ping configuration file from

mmwave_sdk_03_06_02_00-LTS/packages/ti/drivers/pinmux/include/pinmux_xwr18xx.h

PIN Configurations

#define SOC_XWR18XX_PINE13_PADAF_CAN_RX 6U /*< CAN (DCAN) Receive Signal*/
#define SOC_XWR18XX_PINE15_PADAG_CAN_TX 6U /*< CAN (DCAN) Transmit Signal*/

Hi,

Please see the MRR demo configuration. It supports CAN interface

The Example you provided is for FD-CAN. But I need some example to get Normal DCAN Data.

Thanks for providing details in short notice. Could you please also confirm that in AWR1843BOOST, the same J3 Connector provides Normal CAN data as well as the CAN-FD Data based on the project(MCAN/DCAN) configurations

Hi,
Can you please check the AWR1843BOOST schematics.

Hi Cesar, The Schematics does not give clarity of Which CAN pin connected to J3 connector. It is only mentioned as CAN-Tx and CAN-Rx

Please help

Please see the "CAN INTERFACE" section in schematics. The CAN_TX and CAN_RX are connected to TCAN1042HGVDQ1 CAN-FD Transceiver, then from there to J3 connector.

The CAN_TX and CAN_RX are coming from the TS3A5018RSVR switch. This switch is used to select SPI or CAN-FD interface.

So, as you see the lines are different.

You should also use google site search as follows to find some similar threads

site e2e.ti.com awr1843boost dcan

This thread mentions that the dcan lines are routed to the boosterpack connectors. Please see EVM UG.
