Version 1.4.0:

    10

    11

* Replace Sysfs interface with cdev and a user space program

    12

  to replace lsec; move a few sysfs attributes to proc.

    13

* Implement realtime interface via cdev.

    14

* Make scanning and configuration run parallel (each).

    15

* Mailbox state machine using toggle bits.

    16

* Mailbox protocol handlers.

    17

* Remove get_cycles() calls and references to cpu_khz to increase

    18

  portability.

    19

* Remove the end state of the master state machine.

    20

* SDO write access in sysfs.

    21

* Update documentation.

    22

* Supply new ec_master_state_t.

    23

* Adapt remaining examples.

    24

* READMEs for examples.

    25

* Separate Pdo and Pdo entry classes.

    26

* Attach Pdo names.

    27

* Wait for bus scanning, even when link is not up at ecrt_request_master().

    28

* Implement ecrt_slave_config_state().

    29

* Add something like lsec -n to show numeric vendor IDs.

    30

* Remove the xmldev files.

    31

* Separate CoE debugging.

    32

* Make ecrt_master_slave_config() return no error when slave is not present

    33

  or invalid.

    34

* Evaluate EEPROM contents after writing.

    35

    36

Future issues:

    37

    38

* Distributed clocks.

    39

* Move slave handlers and state machines, etc. into a user space daemon (move

    40

  kernel threads to user space daemon with a TCP interface replacing the

    41

  cdev).

    42

* Mailbox gateway.

    43

* Redundancy with 2 network adapters.

    44

* Interface/buffers for asynchronous domain IO.

    45

    46

Smaller issues:

    47

    48

* Evaluate SII Size field (0x003E) to determine maximum SII memory size.

    49

* Unite fsm_pdo_mapping, fsm_pdo_config and fsm_coe_map.

    50

* Clear sync managers in INIT.

    51

* Read out CRC counters.

    52

* Optimize alignment of process data.

    53

* Configure slave ports to automatically open on link detection.

    54

* Only execute one EoE handler per EoE cycle.

    55

    56

Less important issues:

    57

    58

* File access over EtherCAT (FoE).

    59

* Allow VLAN tagging.

    60

* Determine number of frames, the NIC can handle.
