Version 1.5.0:

    12

    13

* Distributed clocks:

    14

    - Check 32/64 bit operations.

    15

    - Use vendor correction factors when calculating transmission delays.

    16

    - Skip setting system time offset when application detached.

    17

    - How to use the SYNC1 shift time?

    18

    - Do not output graph, if topology calculation failed.

    19

    - Set the "Cyclic Generation Start Time" based on the slave's

    20

      "System Time" register instead of using the application time.

    21

    - Check if register 0x0980 is working, to avoid clearing it when

    22

      configuring.

    23

    - Create an interface to query the System Time Difference registers.

    24

* Remove byte-swapping functions from user space.

    25

* EoE:

    26

    - Only execute one EoE handler per cycle.

    29

* Implement 'ethercat foe_read --output-file ...'.

    30

* Use ec_datagram_zero() where possible.

    31

* Fix arguments of reg_read.

    32

* Sign/Abs type for reg_ commands?

    33

* Number layout for reg_read.

    34

* Show Record / Array / List type of SDOs.

    35

* Limit bandwidth of state machine datagram.

    36

* Read alias from register 0x0012 instead of SII.

    37

* Finish library implementation.

    38

* Rescan command.

    39

* Override sync manager size?

    40

* Remove ecrt_domain_state()?

    41

* Check force_config flag before error.

    42

* Remove allow_scanning flag.

    43

* Check for ioctl() interface version.

    44

* Improve application-triggered SDO transfers by moving the state machine into

    45

  the SDO handlers.

    46

* Apply watchdog patches from J. Mohre.

    47

* Move device driver files in subdirectories.

    48

* Document ec_fsm_foe members.

    49

* Test KBUILD_EXTRA_SYMBOLS.

    50

* Remove default buffer size in SDO upload.

    51

    52

Future issues:

    53

    54

* Segmented SDO downloads.

    55

* External memory for SDO transfers.

    57

* C++ implementation of the library.

    58

* Bus simulator interface.

    59

* Move master threads, slave handlers and state machines into a user

    60

  space daemon.

    61

* Allow master requesting when in ORPHANED phase

    62

* Mailbox gateway.

    63

* Separate CoE debugging.

    64

* Evaluate EEPROM contents after writing.

    65

* Optimize alignment of process data.

    66

* Redundancy with 2 network adapters.

    67

* Interface/buffers for asynchronous domain IO.

    68

* Make scanning and configuration run parallel (each).

    69

* ethercat tool:

    70

    - Data type abbreviations.

    71

    - Add a -n (numeric) switch.

    72

	- Check for unwanted options.

    73

* Simplify master fsm by introducing a common request state to handle external

    74

  requests (replace write_sii, sdo_request, etc).

    75

    76

Smaller issues:

    77

    78

* Read out CRC counters.

    79

* Configure slave ports to automatically open on link detection.

    80

* Fix datagram errors on application loading/unloading.

    81

    82

Less important issues:

    83

    84

* Allow VLAN tagging.

    85

* Determine number of frames, the NIC can handle.

    86
