[etherlab-users] "Invalid mailbox configuration", how to configure?

[Stefan Löfgren]

Hmm... 
Looking at "ec_slave_fetch_sii_syncs" in "slave.c"...
This function needs all the SMs in a long row?
This slave's eeprom will produce 4 calls to this function and
allocate the syncs 4 times and ending up with only one sync left!?!?

/S
