Experimental Physics and Industrial Control System
Sorry to have more questions. But I am going in the right direction.
On calling the setup from the IOC I now get:
epics> mrmEvrSetupPCI("EVR-01", "81:0.0")
Device EVR-01 129:0.0 slot=6
Using IRQ 88
FWVersion 0x07020617
Error: Firmware does not correspond to an EVR
Is this a symptom of using 2-2-0? Or is there some simpler explanation/solution? Sounds like the firmware isn't compatible with the support module and/or driver?
Steve

Subject: mrfioc2 Linux driver
Hello all
I am trying to get an MRF PCIe-EVR-300DC configured and working on Linux using mrfioc2. I think I have an IOC built. I think I have some understanding of the parameters to mrmEvrSetupPCI(EVR-01, 1, 0, 0, 0). I could well be wrong on those but that isn't the source of my immediate problem. Executing the previous call gives:
Can't open /sys/module/mrf/parameters/interfaceversion in order to read kernel module interface version. Is kernel module loaded?
I found some documentation that indicates an MRF kernel driver is also required:
$ make -C /location/of/mrmShared/linux \
KERNELDIR=/lib/modules/`uname -r`/build modules_install
$ sudo depmod -a
$ sudo modprobe mrf
I seem to need to execute the first line as root or I get permissions problems. However then I get:
# make -C /home/controls/work/R3.14.12.5/support/mrfioc2/3-0-0/mrmShared/linux KERNELDIR=/lib/modules/`uname -r`/build modules_install
make: Entering directory `/home/controls/work/R3.14.12.5/support/mrfioc2/3-0-0/mrmShared/linux'

make[1]: Entering directory `/usr/src/kernels/3.10.0-514.6.1.el7.x86_64'
Makefile:641: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler

make[1]: Leaving directory `/usr/src/kernels/3.10.0-514.6.1.el7.x86_64'
make: Leaving directory `/home/controls/work/R3.14.12.5/support/mrfioc2/3-0-0/mrmShared/linux'
The documentation dates back to 2015, Rev 7, so may be out of date?
Any advice/help would be much appreciated. Further documentation?
My kernel is 3.10.0-514.6.1.el7.x86_64, mrfioc2 3-0-0
Thanks
Steve
