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

Tue Mar 18 08:43:40 CET 2008

Good morning!

Yes, I tried updating the SII. Using
"cat /sys/ethercat/master0/slave000/sii > slavesii"
Using a hexeditor to change the values and
"cp slavesii > /sys/ethercat/master0/slave000/sii"

Restarting the slave and the master and now the SII seems to be ok.
(well, also removing the hardcoded stuff in fsm_slave_scan.c that I added to
fix this).
I also did "echo 1 > /sys/ethercat/master0/debug_level" at startup just
after the modprobe. (for some strange reason I forgot to set the option for
module unload the the kernel... :( )..

But I can't get it to work.
Can you see if this is a problem in the slave?
