I'm a one of traditional FreeBSD leaf user since Release 2.x and testing
GPIB control with FreeBSD 7.0 Current because of supporting NI PCI-GPIB
interface card.
I finished testing on Red Hat 9, which shows on
http://linux-gpib.sourceforge.net/ but prefer to use with FreeBSD. I have
trouble with controlling tnt4882 driver although appropriate kerenel
configuration and having /dev/gpibxx entry.
I will show testing status
1. Hardware information
Hardware : CPU
CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (3006.83-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0xf43 Stepping = 3
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
Features2=0x649d<SSE3,RSVD2,MON,DS_CPL,EST,CNXT-ID,CX16,xTPR>
AMD Features=0x20100000<NX,LM>
2. Install : FreeBSD 6.2R (i386) -> make update(Mar. 24 2007) with
standard-supfile -> make world, make kernel (No build option & Compile
option in /etc/make.conf )
3. KERNEL CONFIG & Configuration
shell > more /usr/src/sys/i386/conf/GENERIC
...
device pcii
device tnt4882
shell > uname -a
FreeBSD xxx.yyy.com 7.0-CURRENT FreeBSD 7.0-CURRENT #1: Sat Mar 24
15:11:47 KST 2007 root@xxxxxxxxxxx:/usr/obj/usr/src/sys/GENERIC i386
shell > dmesg
...
tnt48820: <NI PCI-GPIB> mem 0xe7207000-0xe72077ff,0xe7200000-0xe7203fff

4. Basic Code Testing
I compiled *IDN? Qurey C code as shown below archive but no response from
instrument (AFG3102, etc and linux-gpib returned good results ).
http://lists.freebsd.org/mailman/htdig/freebsd-hackers/2005-February/010164.html
and modyfied Code returned dmm = 0
/*** PRINT DMM ****/
dmm = ibdev(0, 11, 0, T1s, 1, 0);
printf(" dmm = %d\n", dmm);
if (dmm < 0)
errx(1, "ibdev = %d\n", dmm);
ibwrt(dmm, "*IDN?\r\n", 7);
I think dmm should be dmm > 0, if properly configured. right ?
What is mis-configured ? Please notice me.
