Hi Michael,
this is the message I get when I forget the `main_devices` argument.
The MAC addresses do not need to be valid, so with following commands:
modprobe ec_master
rmmod ec_master
modprobe ec_master main_devices=11:11:11:11:11:11
rmmod ec_master
modprobe ec_master main_devices=11:11:11:11:11:11,22:22:22:22:22:22
rmmod ec_master
give me the following results:
EtherCAT: Master driver 1.5.2 unknown
EtherCAT: 0 masters waiting for devices.
EtherCAT: Master module cleaned up.
EtherCAT: Master driver 1.5.2 unknown
EtherCAT: 1 master waiting for devices.
EtherCAT: Master module cleaned up.
EtherCAT: Master driver 1.5.2 unknown
EtherCAT: 2 masters waiting for devices.
EtherCAT: Master module cleaned up.
Please, double check you are viewing the appropriate messages (do a
`dmesg -c` before inserting the module) and that your shell/terminal
emulator did not messed up your command line.
Ciao.
