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

static int __init init_mini_module(void)




    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
    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
    if (ecrt_slave_conf_sdo16(ec_slave, 0x1C13, 2, 0x1A01)) goto



    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.
