RTOS/AWR1642: How to receive multi-ID using MCAN?

Please provide us more information about sw versions used

thank you

Hi Cesar,

I use the CANFD with SDK1.1.0.2

This is my config:

mcanCfgParams->fdMode = 0x1U;
mcanCfgParams->brsEnable = 0x1U;
mcanCfgParams->txpEnable = 0x0U;
mcanCfgParams->efbi = 0x0U;
mcanCfgParams->pxhddisable = 0x0U;
mcanCfgParams->darEnable = 0x0U;
mcanCfgParams->wkupReqEnable = 0x1U;
mcanCfgParams->autoWkupEnable = 0x1U;
mcanCfgParams->emulationEnable = 0x0U;
mcanCfgParams->emulationFAck = 0x0U;
mcanCfgParams->clkStopFAck = 0x0U;
mcanCfgParams->wdcPreload = 0x0U;
mcanCfgParams->tdcEnable = 0x1U;
mcanCfgParams->tdcConfig.tdcf = 0U;
mcanCfgParams->tdcConfig.tdco = 8U; //For 5Mhz
mcanCfgParams->monEnable = 0x0U;
mcanCfgParams->asmEnable = 0x0U;
mcanCfgParams->tsPrescalar = 0x0U;
mcanCfgParams->tsSelect = 0x0U;
mcanCfgParams->timeoutSelect = CANFD_MCANTimeOutSelect_CONT;
mcanCfgParams->timeoutPreload = 0x0U;
mcanCfgParams->timeoutCntEnable= 0x0U;
mcanCfgParams->filterConfig.rrfe = 0x1U;
mcanCfgParams->filterConfig.rrfs = 0x1U;
mcanCfgParams->filterConfig.anfe = 0x1U;
mcanCfgParams->filterConfig.anfs = 0x1U;
mcanCfgParams->msgRAMConfig.lss = 127U;
mcanCfgParams->msgRAMConfig.lse = 64U;
mcanCfgParams->msgRAMConfig.txBufNum = 32U;
mcanCfgParams->msgRAMConfig.txFIFOSize = 0U;
mcanCfgParams->msgRAMConfig.txBufMode = 0U;
mcanCfgParams->msgRAMConfig.txEventFIFOSize = 0U;
mcanCfgParams->msgRAMConfig.txEventFIFOWaterMark = 0U;
mcanCfgParams->msgRAMConfig.rxFIFO0size = 0U;
mcanCfgParams->msgRAMConfig.rxFIFO0OpMode = 0U;
mcanCfgParams->msgRAMConfig.rxFIFO0waterMark = 0U;
mcanCfgParams->msgRAMConfig.rxFIFO1size = 64U;
mcanCfgParams->msgRAMConfig.rxFIFO1waterMark = 64U;
mcanCfgParams->msgRAMConfig.rxFIFO1OpMode = 64U;
mcanCfgParams->eccConfig.enable = 1;
mcanCfgParams->eccConfig.enableChk = 1;
mcanCfgParams->eccConfig.enableRdModWr = 1;
mcanCfgParams->errInterruptEnable = 1U;
mcanCfgParams->dataInterruptEnable = 1U;
mcanCfgParams->appErrCallBack = MCANAppErrStatusCallback;
mcanCfgParams->appDataCallBack = MCANAppCallback;

I want to use Range filter for Identifier of rx.

Jui Yang,

The issue is in setting the "extMsgIdFilter.efec = 0x7U". If you set the EFEC :0x07, then the configuration of the "EFT[1:0]" is ignored . You cannot use the buffer to store the range filtered messages.

You can set the EFEC so that the received message is stored in the FIFO.

Please make the changes to EFEC to resolve your issue.

Thanks,

Hi Raghu,

I try change extMsgIdFilter.efec =0x2U.
But the CAN-FD can't receive message when ID=(msgId) or =(msgId+0x100) .
Do other lines need to change?

Hello JuiYang,

Could you please post all the code changes done by you in this thread? I would like to review your changes once.

Thanks,

Raghu

Hi,

This is my change below:

In main.c, change mcanCfgParams->msgRAMConfig.rxFIFO0size, mcanCfgParams->msgRAMConfig.rxFIFO0OpMode and mcanCfgParams->msgRAMConfig.rxFIFO0waterMark .

In canfd.c, change extMsgIdFilter.efid2, extMsgIdFilter.efec and extMsgIdFilter.eft .

Regards,

Hello Jui Yang,

I did check the changes and see that the "Range filter " does not seem to be working. Will debug this further and provide you the solution asap.

Thanks for your patience.
