[etherlab-users] Etherlab ec_master : Kernel Errors

[pier]

Dear Olaf


The CoE program is written in perl, accessing to /dev/Ethercat0

I do not know if is accessing with variable length arrays....

If I use only the perl program is working ...

But if meantime also another task that is handling the ethercat frame 
structure

there freezing appears....

May be sending  CoE Messagges to more device at the same time ?



Best Regards

Pier
