[Etherlab-users] The phenomenon that SAFEOP does not transmit FMMU packet

[임병근]

Hi all


I have problem is that the state is not changed with SAFEOP -> OP.
Compared to Twincat, it seems that SAFEOP does not blow the FMMU configuration packet.
Where would you like to check?
Also, what kind of information do you need to solve this problem???


I am running it on NXP imx8mp eval board


First of all, the Cstruct of Ethercat slave is as follows.


 /* Master 0, Slave 0, "ARIO-C-EC"
 * Vendor ID: 0x00000759
 * Product code: 0x00000003
 * Revision number: 0x000d0001
 */


ec_pdo_entry_info_t slave_0_pdo_entries[] = {
    {0x7010, 0x01, 8}, /* Byte 1 */
    {0x6000, 0x01, 8}, /* Byte 1 */
};


ec_pdo_info_t slave_0_pdos[] = {
    {0x1601, 1, slave_0_pdo_entries + 0}, /* RxPDO Mapping Slot #01 */
    {0x1a00, 1, slave_0_pdo_entries + 1}, /* TxPDO Mapping Slot #00 */
};


ec_sync_info_t slave_0_syncs[] = {
    {0, EC_DIR_OUTPUT, 0, NULL, EC_WD_DISABLE},
    {1, EC_DIR_INPUT, 0, NULL, EC_WD_DISABLE},
    {2, EC_DIR_OUTPUT, 1, slave_0_pdos + 0, EC_WD_ENABLE},
    {3, EC_DIR_INPUT, 1, slave_0_pdos + 1, EC_WD_DISABLE},
    {0xff}
};


Thank you
