Experimental Physics and
Industrial Control System

Dear All,

 

With the help of Dr. Han, I was able to run mrfioc2.

However, I have one question.

 

I have one EVG and two EVRs as shown below.

(mTCA-EVM-300, mTCA-EVR-300, mTCA-EVR-300RF)

I checked it by referring to lspci of mrfioc2 to distinguish 3 cards.

In the document above, the device name is specified in the subsystem item as shown below, but I do not.

 

06:00.0 Signal processing controller: Xilinx Corporation XILINX PCI DEVICE

        Subsystem: Micro-Research Finland Oy MTCA Event Master 300

        Physical Slot: 4

 

I couldn't distinguish between EVG and EVR, so I had to run them one by one.

Subsystem: Device 1a3e:132c

Is there no problem if I separate it into the above information?

1a3e:232c is mTCA-EVM-300.

1a3e:132c is mTCA-EVR-300RF or mTCA-EVR-300.

I can distinguish the two EVRs after the IOC runs.

Is there any way to know before the IOC is implemented?

Subject: Re: linux kernel module for mrfioc2 on MTCA

 

The actual kernel driver is located in

https://github.com/epics-modules/mrfioc2/tree/master/mrmShared/linux

 

There are several methods you may try, here is also very old repo, but you can find "dkms" information there.

 

https://github.com/icshwi/e3-mrfioc2/

 

Best,

Han

Hi Geonyeong,

 

Please use the kernel driver for mrfiioc2 instead of what you used.

 

https://github.com/epics-modules/mrfioc2

 

PCIID is not up-to-date, if you want to see through lspci, please check my own archived repo.

HTH,

Han

Dear All,

I am trying to MTCA-EVG-300 and MTCA-EVR-300U are working on Linux using mrfioc2.
But, the following error is displayed:

epics> mrmEvgSetupPCI("EVG",08,00,0)
Can't open /sys/module/mrf/parameters/interfaceversion in order to read kernel module interface version. Kernel module not loaded or too old.

I used the latest version driver provided by MRF. https://github.com/jpietari/mrf-linux-driver
Do I have to use a driver other than this one?

The mrf directory does not exist In the /sys/module directory.
Instead, pci_mrfevg, pci_mrfevr exists.
