Re: [Linux-gpib-general] PCMCIA GPIB help with linux-gpib-4.3.0

[dave p. <dpe...@gm...>]

Hi Mitchell,
The kernel module for ni_pcmcia and ni_pcmcia_accel is the tnt4882.ko
module which seems to exist from your dmesg.
We forgot to put a GPIB_CONFIG_PCMCIA config option into the Makefile when
autoconf was dropped for the kernel modules build.
Please edit the "all" target in the top level Makefile in the
linux-gpib-kernel-4.3.0 directory to look like so:
all:
    -$(MAKE) -C $(LINUX_SRCDIR) V=$(VERBOSE) modules \
        M="$(GPIB_SRCDIR)/drivers/gpib" \
        GPIB_TOP_DIR=$(GPIB_SRCDIR) \
        CONFIG_GPIB_ISA="$(ENABLE_ISA)" \
        HAVE_DEV_OF_NODE=$(HAVE_DEV_OF_NODE) \
        GPIB_CONFIG_KERNEL_DEBUG=$(GPIB_DEBUG) \
        GPIB_CONFIG_PCMCIA=1

Rebuild and install the kernel modules with the above modification and
reboot to test.
BTW: The gpib_config command should be: gpib_config --minor 0.
Cheers,
-Dave
