[Hobin Yoon]

I've removed unused SDOs by trial and error. Please find the attached
file. According to the 'CoE-Online' tab, I've added SDO configuration
functions.

static int __init init_mini_module(void)
{
    ecrt_request_master();

    ecrt_master_callbacks();

    ecrt_master_create_domain();

    ecrt_master_get_slave();

    if (ecrt_slave_conf_sdo8(ec_slave, 0x1C12, 0, 1)) goto out_release_master;
    if (ecrt_slave_conf_sdo16(ec_slave, 0x1C12, 1, 0x1600)) goto
out_release_master;
    if (ecrt_slave_conf_sdo8(ec_slave, 0x1C13, 0, 2)) goto out_release_master;
    if (ecrt_slave_conf_sdo16(ec_slave, 0x1C13, 1, 0x1A00)) goto
out_release_master;
    if (ecrt_slave_conf_sdo16(ec_slave, 0x1C13, 2, 0x1A01)) goto
out_release_master;

    ecrt_domain_register_pdo_list();

    ecrt_master_activate();

    start timer
}

Unfortunately, it gives the following errors after ecrt_master_activate().

EtherCAT ERROR: Timeout while checking SDO configuration on slave 0.
EtherCAT ERROR: SDO configuration failed for slave 0.
EtherCAT ERROR: Failed to configure slaves.

Regarding the DC, my XML has the following DC element. It seems to be
needed since it didn't work when removed in TwinCAT.

<Dc>
	<OpMode>
		<Name>Distributed Clocks</Name>
		<Desc>Distributed Clocks</Desc>
		<AssignActivate>#x0700</AssignActivate>
	</OpMode>
</Dc>

Best Regards,
Hobin Yoon
