HI
That seems to be due to non-default -Wmissing-field-initializers, right?
Will have a look if we can quiet gcc.
Possible. I have received your patch. Will apply it (have to figure
out how first) later and give feedback.

rt_task_shadow() is required if you call blocking services like
rt_task_wait_period from a task AND you didn't create it via some other
native service (rt_task_spawn or rt_task_create/start).
Well then my code should be correct.
If the problem persists even with clean rt_task setup (rt_task_shadow
etc.), I guess it's best you post your code.
Without changing my code I cannot repeat the behavior myself. Very
strange. I have tried just about everything but after starting up the
PC this morning there is no way I can repeat the behaviour I describe
above.
So the can_write seems to be working for now. If it happens again I
will post the code.
I have more of a problem with reading. I am doing something wrong. The
program does not return from the call rt_dev_recvfrom. Below is the
simple read function I am presuming that whatever I am doing wrong
will be blatantly obvious to all except me:)
void can_read(const char * device, can_frame_t * frame){
int ret;
struct ifreq ifr;
struct sockaddr_can addr;
socklen_t addrlen = sizeof(addr);
struct sockaddr_can recv_addr;
strncpy(ifr.ifr_name, device, IFNAMSIZ);
ret = rt_dev_ioctl(can_fd, SIOCGIFINDEX, &ifr);
if (ret < 0) {
fprintf(stderr, "rt_dev_ioctl get index: %s\n", strerror(-ret));
return;
}
recv_addr.can_family = AF_CAN;
recv_addr.can_ifindex = ifr.ifr_ifindex;
ret = rt_dev_bind(can_fd, (struct sockaddr *)&recv_addr,
sizeof(struct sockaddr_can));
if (ret < 0) {
fprintf(stderr, "rt_dev_bind: %s\n", strerror(-ret));
return;
}
printf("going in");
ret = rt_dev_recvfrom(can_fd, (void *)frame, sizeof(can_frame_t), 0,
(struct sockaddr *)&addr, &addrlen);
printf("coming out");
}//can_read
