Hi all,
I'm running FreeBSD 5.0-RC2 on my DELL Precision 530 and I've
troubles reading from /dev/fw*. I've compiled kernel with
"device firewire" and after connecting camera SONY TRV-30E
it seem that device is found OK - dmesg output from boot while
camera is on is attached bellow my signature.
When I boot the machine without camera attached and attach
it afterwards I get following messages:
----

I tried to get anything from fw* devices in following ways (in both
cases with camera attached before boot and after boot I get the same
results; all the commands performed as a root):
* dd if=/dev/fw0 of=test
---
-su-2.05b# for i in 0 1 2 3; do dd if=/dev/fw${i} of=test; done

* cat /dev/fw0
---

cat: /dev/fw0: Resource temporarily unavailable
cat: /dev/fw1: Resource temporarily unavailable
cat: /dev/fw2: Resource temporarily unavailable
cat: /dev/fw3: Resource temporarily unavailable
---
* using C program that does roughly following (ioctl's
are from DVTS):
if ((fd = open("/dev/fw0", O_RDWR)) < 0) {perror...}
bufreq.rx.nchunk = 4;
bufreq.rx.npacket = 25;
bufreq.rx.psize = 512;
bufreq.tx.nchunk = 10;
bufreq.tx.npacket = 2000;
bufreq.tx.psize = 512;
if (ioctl(fd, FW_SSTBUF, &bufreq) < 0) {perror...}
isoreq.ch = 63;
isoreq.tag = 0;
if (ioctl(fd, FW_SRSTREAM, &isoreq) < 0) {perror...}
len = read(dvsend_param->ieee1394dv.fd, recvbuf, 512);
if (len < 1) {
printf("ieee1394 recv len : %d\n", len);
break;
}
I get following:
---
-su-2.05b# ./test_fw
ieee1394 recv len : -1
/dev/fw0 read: Resource temporarily unavailable
---
BTW:
---
-su-2.05b# ls -l /dev/fw*

crwxrwx--- 1 root operator 127, 1 Dec 30 22:10 /dev/fw1

crwxrwx--- 1 root operator 127, 0x01000000 Dec 30 22:10 /dev/fwmem0
---
A small sidenote: when I was playing with this device using C
I found I need to include:
#include "/sys/dev/firewire/firewire.h"
to get to constants and structures like FW_SSTBUF and bufreq.
Why is this header not included somewhere in /usr/include?
Am I supposed to treat this device in some other special way? BTW: I
was able to use this camera with some other machine that runs
FreeBSD 4.6.2 with patch from DVTS (patched once again by myself
because of lazy BIOS on that machine, see
http://cheminfo.chemi.muni.cz/~hopet/FreeBSD/ASUS_T9400.html
if interested) so I think camera is OK.
Thanks very much in advance for your help and the best wishes for 2003!
