Hi

 

>> WARNING: "ecrt_master_..."

Copy or link the $(PATH_TO_EC_MASTER)/Module.symvers to your mini-directory.

1)       Have you started your Master? 

2)       Check dmesg for more infos.

Betreff: [etherlab-users] Problem running examples::mini

 

Hi,

I am new in ethercat and I am getting problems with the example mini.

I am using ethercat 1.5.2, Ubunto 12.04.2,  linux kernel version
3.5.0-23-generic, the generic Ethernet driver and two proprietary ethercat
slaves.

I follow the installation instructions and manage to configure and make
modules. I start the master manually with ethercat start and get following
system messages with dmesg:

 

[11789.921570] EtherCAT: Master driver 1.5.2 2eff7c993a63

[11789.921708] EtherCAT: 1 master waiting for devices.

[11789.927170] ec_generic: EtherCAT master generic Ethernet device module
1.5.2 2eff7c993a63

[11789.927193] EtherCAT: Accepting 5C:26:0A:1E:C7:E0 as main device for
master 0.

[11789.927205] ec_generic: Binding socket to interface 2 (eth0).

[11789.928833] EtherCAT 0: Starting EtherCAT-IDLE thread.

[11789.928892] EtherCAT 0: Link state of ecm0 changed to UP.

[11789.932772] EtherCAT 0: 2 slave(s) responding on main device.

[11789.932778] EtherCAT 0: Slave states on main device: PREOP.

[11789.933336] EtherCAT 0: Scanning bus.

[11790.660653] EtherCAT 0: Bus scanning completed in 728 ms.

[11790.660658] EtherCAT 0: Using slave 0 as DC reference clock.

 

I then change the processing data part of mini.c to match my hardware (slave
positions, vendor and products ids). I then delete the .o files generated in
my initial make modules after installing ethercat. I run make modules again
and obtain many undefined:

 

root at ethercat-test:~/Desktop/ethercat/ethercat-1.5.2/examples/mini# make
modules

make -C "/usr/src/linux-headers-3.5.0-23-generic"

All these undefined mean to me the module was not well built, isn't it?

 

In spite of having problems building the module, I tried anyway insmod  and
get an error: 

 

root at ethercat-test:~/Desktop/ethercat/ethercat-1.5.2/examples/mini# insmod
ec_mini.ko

insmod: error inserting 'ec_mini.ko': -1 Invalid parameters

 

What could be wrong? 

 

Thanks for any advice

 

Uriel
