TDA4VM: TDA4VM main域CAN ID过滤配置27个ID，但是只生效了前25个

请尝试加大堆栈试试。

请问是系统的堆栈吗，在哪里配置的呢

我把您的问题升级到英文e2e了

能否发一下您图2的代码？图片看不清，太小了。

stdFiltelem.sfec = 0x7;

stdFiltelem.sft = 0x0;

for(i = 0; i < (sizeod(gCanCmdParamConfig[mcanIdx])/sizeof(gCanCmdParamConfig[mcanIdx][0])); i++)

{

   if(gCanCmdParamConfig[mcanIdx][i].can_id[0] == 0)

   {

       continue;

   }

   stdFiltelem.sfid2 = i;

   stdFiltelem.sfid1 = gCanCmdParamConfig[mcanIdx][i].can_id[0];

  MCAN_addStdMsgIDFilter(mcanAddr, i, &stdFiltelem);

}

程序对一个需要过滤的ID表，不断通过MCAN_addStdMsgIDFilter()添加过滤ID，然后一共是27个，但是只有前25个起作用了，后两个ID的报文收不到

这个APP_MCAN_EXT_ID_FILTER_NUM宏定义不是代表扩展CANID的吗，但是我需要过滤的是标准ID，应该是APP_MCAN_STD_ID_FILTER_NUM才对，我把它改成了64

已把您的问题更新到e2e帖子，请关注帖子的回复。

请参考下面工程师的回复。

Does APP_MCAN_EXT_ID_FILTER_NUM macro refer to CANID extension? Customer wanted to filter the standard ID, he set APP_MCAN_STD_ID_FILTER_NUM to 64, is it correct?

Yes, the APP_MCAN_EXT_ID_FILTER_NUM is for filters for extended ID, APP_MCAN_STD_ID_FILETER_NUM is correctly set to 64U.c It's maximum value can be 128U.

The configuration seems correct, is it possible to share the full application code from the customer so that I can try replicating this on my side on the EVM?
