My IOC is built but I have trouble with xspress3config, note that my Xspress3 chassis has more than 4 channels.

I changed the Y_SIZE (max_channels)  in xspress3/iocs/xspress3IOC/iocBoot/iocxspress3-4Channel/st.cmd to 6

xspress3Config("XSP3", "6", "1", "192.168.0.1", "16384", 16384, "4096", 0, 0, 1, 0)

but I get messages from xsp3_config that I don't understand

Do you have and are you loading Xspress3 settings and calibrations files for 6 channels or for 4 channels?  Somewhere in the IOC startup, you have to define where these settings files are, with something like

     dbpf("$(PREFIX)det1:CONFIG_PATH", "/home/xspress3/xspress3_settings/current/")

And these settings really should be for the correct number of channels.  If you change the number of channels I believe you need to remove the shared memory files in /dev/shm/xsp3*.  These files will be re-created when the IOC restarts the xspress3 server.
