Other Parts Discussed in Thread: DM3730
Hi, i am trying to implement camera driver to dm3730 on beagleboard, i have FPGA connected to camera interface and i sumulate PCLK, HS, VS and DATA signals. i wrote my driver as follows:

when i insert module everything is ok, there is new video0 device in dev. When i try to test it, hangs on
while (count-- > 0) {
for (;;) {
fd_set fds;
struct timeval tv;
int r;
FD_ZERO(&fds);
FD_SET(fd, &fds);
/* Timeout. */
tv.tv_sec = 2;
tv.tv_usec = 0;
r = select(fd + 1, &fds, NULL, NULL, &tv);
if (-1 == r) {
if (EINTR == errno)
continue;
errno_exit("select");
}
if (0 == r) {
fprintf(stderr, "select timeout\n");
exit(EXIT_FAILURE);
}
if (read_frame())
break;
/* EAGAIN - continue select loop. */
}
it gives me select timeout :( when i try to skip select part, it hangs on DQBUF ioctl, when i start v4l2-test it gives me:
