I have two Advantech PCI-1760 digital I/O cards. I've tested them with
Windows and they seem to be working: I can ground the inputs and the
little indicators on the screen turn green when I do, and when I click
the output buttons, the little read led's on the board turn on and off
as expected.
But...
My application is for linux. I have two machines that give similar
results, both run Debian Sarge, one with a stock Debian 2.4.27 kernel
and one with a locally compiled 2.6.8 kernel. I have comedi kenrel
modules 0.7 installed, and libcomedi 0.7.22 installed. When I load the
driver modules: comedi.o and either pci1760.o or adv_pci_dio.o and run:
comedi_config /dev/comedi0 pci1760
it appears to work.
But when I run my test program, or the di_insn or do_insn programs, the
driver logs the following:
kernel: comedi0: adv_pci_dio: PCI-1760 mailbox request timeout!
and none of the operations work. They all return success, but the led's
never come on when I do an output, and I always read 0xF7 when I do an
input.
Here is the result of comedi_test on the 2.6.8 box:

I noticed the the channels seem to be re-ordered, but the software
notices and acts appropriately, but when I read or write the DIO bits,
nothing happens on output and on input I always get 0xF7 no matter which
bits I have open or grounded.
Any help at all would be greatly appreciated.
Thanks in advance.
