Remora - ethernet NVEM / EC300 / EC500 cnc board

hello, I managed to insert the firmware, I managed to ping my nvemV2 10.10.10.10, i also managed to do halcompile, i also transferred some of the basic configurations... unfortunately, starting linuxcnc via the command line, I get a blank, i.e. I can't start either one of the configurations. do you have any ideas? Thank you
