Part Number: TDA4VM
I am a software engineer，I want to know that TDA4 can support the socket can mechanism.
If the TDA4 support the socket can mechanism,there is a way to dertermin the can is bus_off.
I find a way like this.
struct can_frame framesend =
{
.can_id = 0xaa,
.can_dlc = 1,
.data[0] = 0x66,
}
err = write(s_can0,&framesend,sizeof(framesend));
if(err <= 0)
{
perror("send data error");
}else{
if(framesend.can_id & CAN_ERR_BUSSOFF)
perror("bus-off");
}
I try that way.but it doesn't works.
So I want to know that if I use the socket_can system,
there is a way to determine that now the can device is bus_off.
Thanks!!!
Best wishes!!!
