     7

Changes in version 1.3.2:

     8

     9

* New feature: Read dynamic PDO mapping from SDO dictionary.

    10

* Implemented SII writing workaround for some broken slaves.

    11

* Improved handling for spontaneous AL state changes.

    12

* Master takes mailbox sync manager configurations from EEPROM words

    13

  0x0018-0x001b, if no sync manager configurations are provided.

    14

* Calculate checksum when writing EEPROM or alias address.

    15

* Fixed source MAC address setting bug.

    16

* Removed config.kbuild and replaced Kbuild files by Kbuild.in files.

    17

    18

-------------------------------------------------------------------------------

    19

    20

Changes in version 1.3.1:

    21

    22

* Improved EoE handling: Avoided skipping of datagrams and release lock

    23

  while processing.

    24

* Added some statistics to the datagram structure.

    25

* Master state machine clears all station addresses with a broadcast datagram

    26

  before setting them.

    27

* Added --enable-eoe conditional.

    28

* Minor extensions of the master info file.

    29

* Improved handling of unexpected working counters.

    30

* Create network interfaces for EoE devices with alias as eoeXaY.

    31

* Fixed problems on big-endian systems.

    32

* Added documentation on how to set up an EoE network.

    33

    36

Changes in version 1.3.0:

    37

    38

* Added Intel PRO/1000 Gigabit Ethernet driver (e1000).

    39

* Added testing version of Intel PRO/100 Ethernet driver (e100).

    40

* Added testing version of NVIDIA nForce Ethernet driver (forcedeth).

    41

* Removed "ec_eoeif_count" master module parameter. EoE handlers are created

    42

  dynamically instead.

    43

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

    44

  MAC addresses of the devices to wait for. This made the ec_device_index

    45

  parameter of the Ethernet drivers obsolete. The broadcast MAC address means,

    46

  that the master accepts the first device offered by any Ethernet driver.

    47

* Changed format of sysconfig file and accordingly adjusted functionality

    48

  of the init script to handle the above MAC address lists.

    49

* Realtime interface changes:

    50

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

    51

    run in process context.

    52

  - Parameter changes in PDO registration functions ecrt_domain_register_pdo()

    53

    and ecrt_register_pdo_range(): Replaced slave_address, vendor ID and

    54

    product code arguments with a slave pointer, which has to be obtained with

    55

    a prior call to ecrt_master_get_slave().

    56

  - ecrt_master_get_slave() got additional parameters to check for vendor ID

    57

    and product code.

    58

  - Removed addressing scheme "X:Y" for ecrt_master_get_slave().

    59

  - Added ecrt_master_get_slave_by_pos() to avoid the string handling of

    60

    ecrt_master_get_slave().

    61

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

    62

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

    63

    ec_slave_pdo_mapping_clear(), ec_slave_pdo_mapping_add() and

    64

    ec_slave_pdo_mapping().

    65

* Device interface changes:

    66

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

    67

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

    68

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

    69

  - Replaced ecdev_link_state() with ecdev_set_link(); added ecdev_get_link().

    70

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

    71

  writing has finished. Appropriate error codes are returned.

    72

* Implemented setting of the "Secondary slave address" (alias) via sysfs.

    73

* Implemented SDO reading in operation mode via sysfs.

    74

* Removed annoying eeprom_write_enable file. EEPROM writing always enabled.

    75

* Slave configuration is now done exclusively from the master thread. Removed

    76

  ec_master_sync_io(). Userspace threads are now waiting for events in the

    77

  state machine.

    78

* Master state machine scheduled with timeout if idle, otherwise is executed

    79

  as fast as possible (with schedule()).

    80

* Added dummy module for simulation purposes.

    81

* Limited infinite EEPROM reading, if 0xffff limiter word is missing.

    82

* Init script works now properly on non-SUSE distros (no rc.status dependency

    83

  any more).

    84

* Removed EtherCAT line comments from 8139too drivers.

    85

    86

    87

    88

Changes in version 1.2.0:

    89

    90

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

    91

  with kernels 2.6.17 to 2.6.19.

    92

* Realtime interface changes:

    93

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

    94

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

    95

    done in ecrt_domain_process() any more!

    96

  - Removed ecrt_master_deactivate(). Its functionality was moved into

    97

    ecrt_master_release().

    98

  - Removed ecrt_master_prepare(). Its functionality was moved into

    99

    ecrt_master_activate().

   100

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

   101

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

   102

  - The data_ptr parameter of ecrt_domain_register_pdo(),

   103

    ecrt_domain_register_pdo_list() and ecrt_domain_register_pdo_range() may

   104

    not be NULL any more.

   105

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

   106

  - Introduced ECRT_VERSION_MAGIC macro and ecrt_version_magic() function.

   107

* Device interface changes:

   108

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

   109

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

   110

    drivers' interrupt functions have different arguments.

   111

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

   112

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

   113

  remaining current.

   114

* Added frame counter in master info file.

   115

   116

   117

   118

Changes in version 1.1.1:

   119

   120

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

   121

* Added modules_install make target.

   122

* Device modules for kernel 2.6.17.

   123

* SDO configurations available in Sysfs.

   124

* FMMU configurations cleared when going to INIT.

   125

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

   126

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

   127

* Acknowledging of spontaneous state changes in master FSMs.

   128

* ecrt_master_deactivate() deprecated.

   129

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

   130

  change in IDLE mode.

   131

* SDO reading via Sysfs.

   132

* Added ecrt_domain_register_pdo_range()

   133

* Fetching of SDO dictionary.

   134

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

   135

* Applied Autotools.

   136

* Improved output of lsec.

   137

* SDO download state machine.
