AWRL1432BOOST-BSD: TCAN4550 is defined, CLI Bypass Enabled, but can't get the CAN data from the board

Part Number: AWRL1432BOOST-BSD
Other Parts Discussed in Thread: TCAN4550, AWRL1432, INA228

Tool/software:

Hi expert,

I enable CLI Bypass and configure parameter same with the profile_40m_40mpsec_boostevm_16tracks.cfg, meanwhile define TCAN4550(1) and use "CANFDLLD_MCANFrameType_CLASSIC" frametype.

When I debug the board (awrl1432_adas_bsd_demo_v2.2, MMWAVE_L_SDK_05_05_00_02), I find that the UART can output data normally, and the code can run into "TCAN4550_Transmit_Schedule" function, but I use Vector(set 500k baudrate) still can't get data from CAN, it made me confused, could you help me to confirm the problem?

BTW, I closed all INA228 relevant code, because if not, it will report error.

Hi,

Were you able to receive CAN data before you made the changes?

Thanks,

Clinton

Hi Clinton,

I just test it, use prebuilt_binaries"awrl1432_adas_bsd_demo_es2.appimage" in "awrl1432_adas_bsd_demo_v2.2" demo folder, meanwhile the GUI can show the point cloud, but use vector(setting 500kbps arbitration and 2000kbps data rate) still can't get CANFD data. Maybe the vector setting is wrong? or the prebuilt_binaries don't transmit CANFD data? Looking forward to your kindly advice~

Best regards,

Hi Daowei,

Thanks for the information. TCAN4550 should be enabled in the prebuilt binary.

Could you confirm that the HW setup? On the EVM, switches S1.6 and S4.4 should be on to enable SPI and the TCAN-SPI connection and press the CAN_WAKE switch (S6) to put the TCAN4550 into standby mode.

I'm not familiar with the CAN analyzer from Vector, but here are the timing parameters used (500kbps/2000kbps) :

Thank you,

Jin

Hi Jin,

Your suggestion has solved the CAN output problem, the key is the CAN_WAKE switch (S6) button you mentioned. Thank you a lot!
