Pardon for the noob question, but I have Etherlab 1.5.2 set up on a Fedora 19 system, and have a strange issue with reserving a master instance.
To start with, I *should* have read/write permission on the device:[dclark@bukhansan Debug_ecat]$ ls -l /dev/EtherCAT0 crw-rw-r--. 1 root users 249, 0 Jan 1 13:33 /dev/EtherCAT0 But when I wrote the simplest possible application to just request and then release the master to check I had all the build and link options set correctly, I got the following error: [dclark@bukhansan Debug_ecat]$ ./TestServo Failed to open /dev/EtherCAT0: Permission denied FATAL: couldn't request a master instance. Running it as root: [root@bukhansan Debug_ecat]# ./TestServo Master instance created ok Releasing master...done! Any ideas why this would be? Thanks in advance! Dusty Clark MMT Observatory
