I am trying to get a Measurement Computing PCIM-1602/16 working with Comedi. The web site (http://www.measurementcomputing.com/cbicatalog/cbiproduct_new.asp?dept_id=139&pf_id=1468&mscssid=3KFTFJXB4HR88HABPQHC81HNCFW3E729) indicates that this is not the same as a PCI-1602/16, but is more like a CIO-DAS1602/16 with PCI interface. The PC is running RedHat 7.3 (2.4.18-3 kernel, gcc 2.96-110) The board is functioning to a basic level, /proc/pci reports: [root_at_cook root]# cat /proc/pci PCI devices found: <snip> Bus 0, device 19, function 0: Class ffff: PCI device 1307:0056 (Computer Boards) (rev 2). IRQ 11. Non-prefetchable 32 bit memory at 0xf0000000 [0xf000007f]. I/O at 0x6000 [0x607f]. I/O at 0x6100 [0x6107]. I/O at 0x6200 [0x620f]. I/O at 0x6300 [0x6303]. Comedi 0.7.65 built and installed correctly. The module is loading successfully: [root_at_cook root]# modprobe das16 [root_at_cook root]# lsmod Module Size Used by Not tainted das16 12960 0 (unused) 8255 2656 0 [das16] comedi 20104 0 [das16 8255] ne 7648 1 8390 7780 0 [ne] ide-cd 30400 0 (autoclean) cdrom 32032 0 (autoclean) [ide-cd] but calling comedi_config gives: [root_at_cook root]# comedi_config /dev/comedi0 cio-das1602/16 Configure failed!: Input/output error Check kernel log for more information Possible reasons for failure: Driver not found [root_at_cook root]# tail /var/log/messages Nov 4 14:38:01 cook modprobe: modprobe: Can't locate module char-major-98-0 Nov 4 14:38:01 cook kernel: comedi0: das16: 0x0000-0x000f 0x0400-0x0408 Nov 4 14:38:01 cook kernel: I/O port conflict: 0x0000-0x000f Nov 4 14:38:01 cook kernel: comedi0: das16: remove Nov 4 14:38:01 cook kernel: Trying to free nonexistent resource <00000000-0000000f> Nov 4 14:38:01 cook kernel: Trying to free nonexistent resource <00000400-00000407> If I try # comedi_config /dev/comedi0 cio-das1602/16 0x6000 to specify the base address as shown in /proc/pci, the computer locks solid. Any ideas? Richard Bytheway
