Changes in version 1.3.0:

     8

    11

* Removed "ec_eoeif_count" master module parameter.

    12

* Introduced "Device IDs" to tell a master to wait for connection of certain

    13

  ethernet devices.

    14

* Added "main" and "backup" parameters to master module to hand over

    15

  device ID lists.

    16

* Changed format of sysconfig file and accordingly adjusted functionality

    17

  of the init script to handle device ID lists.

    18

* Realtime interface changes:

    19

  - ecrt_master_run() became obsolete, because the master state machine is now

    20

    run in process context.

    21

  - Added ecrt_master_get_status() to get information about the bus.

    22

  - Added functions to set up an alternative PDO mapping, i. e.

    23

    ec_slave_pdo_mapping_clear(), ec_slave_pdo_mapping_add() and

    24

    ec_slave_pdo_mapping().

    25

* Device interface changes:

    26

  - Replaced ecdev_register() and ecdev_unregister() with ecdev_offer() and

    27

    ecdev_withdraw(), respectively. The device modules now offer all their

    28

    devices to the master, which decides, which ones to register.

    29

* All EEPROM write operations from user space are now blocking until

    30

  writing has finished and return appropriate error codes.

    31

* Implemented setting of secondary slave address (alias) via sysfs.

    32

* Removed annoying eeprom_write_enable file. EEPROM writing always enabled.

    33

* Removed EtherCAT line comments from 8139too drivers.

    37

Changes in version 1.2.0:

    38

    39

* Serveral fixes of bugs and stability issues. Master should now run fine

    40

  with kernels 2.6.17 to 2.6.19.

    41

* Realtime interface changes:

    42

  - Re-introduced ecrt_domain_queue() to allow datagram queuing apart

    43

    from datagram processing. The queuing of a domain's datagrams is not

    44

    done in ecrt_domain_process() any more!

    45

  - Removed ecrt_master_deactivate(). Its functionality was moved into

    46

    ecrt_master_release().

    47

  - Removed ecrt_master_prepare(). Its functionality was moved into

    48

    ecrt_master_activate().

    49

  - Renamed ecdev_start() and ecdev_stop() to ecdev_open() and ecdev_close().

    50

    These two functions now take a pointer to ec_device_t as their arguments.

    51

  - The data_ptr parameter of ecrt_domain_register_pdo(),

    52

    ecrt_domain_register_pdo_list() and ecrt_domain_register_pdo_range() may

    53

    not be NULL any more.

    54

  - Removed ecrt_slave_pdo_size(). This function was deprecated long before.

    55

  - Introduced ECRT_VERSION_MAGIC macro and ecrt_version_magic() function.

    56

* Device interface changes:

    57

  - ec_isr_t was replaced by ec_pollfunc_t, the device driver has to supply

    58

    a poll function to call its ISR. This was introduced because some network

    59

    drivers' interrupt functions have different arguments.

    60

* State machines now try to re-send datagrams on datagram timeout.

    61

* New option -c of the lsec script, displays slave current consumptions and

    62

  remaining current.

    63

* Added frame counter in master info file.

    64

    67

Changes in version 1.1.1:

    68

    69

* State change FSM: Clearing of sync managers before PREOP.

    70

* Added modules_install make target.

    71

* Device modules for kernel 2.6.17.

    72

* SDO configurations available in Sysfs.

    73

* FMMU configurations cleared when going to INIT.

    74

* Slave-specific logs only at debug level 1 (for large busses).

    75

* Slave flags (error, online) available in Sysfs.

    76

* Acknowledging of spontaneous state changes in master FSMs.

    77

* ecrt_master_deactivate() deprecated.

    78

* Persistent slave lists. Slave structures are only regenerated on topology

    79

  change in IDLE mode.

    80

* SDO reading via Sysfs.

    81

* Added ecrt_domain_register_pdo_range()

    82

* Fetching of SDO dictionary.

    83

* Better timing behaviour when starting up under high CPU load.

    84

* Applied Autotools.

    85

* Improved output of lsec.

    86

* SDO download state machine.
