Version 1.4.0: |
547 | 10 |
|
776 | 11 |
* Realtime interface changes: |
12 |
- SDO access. |
|
13 |
- External memory for domains. |
|
14 |
* Mailbox handler |
|
15 |
* Read PDO mapping via CoE during bus scan. |
|
16 |
* SDO write access in sysfs. |
|
17 |
* Remove get_cycles() calls and references to cpu_khz to increase |
|
18 |
portability. |
|
19 |
* Remove ecdb.h and let lsec output PDO information 'cut-and-pastable' for |
|
20 |
applications. |
|
21 |
* Update documentation. |

|
26 |
* Implement all EtherCAT datagram types. |
547 | 27 |
|
776 | 28 |
Future issues: |
29 |
||
30 |
* Move slave handlers and state machines, etc. into a user space daemon. |
|
31 |
- Step 1: Replace Sysfs interface with cdev and a user space program |
|
32 |
to replace lsec. |
|
33 |
- Step 2: Move kernel threads to user space daemon with a TCP interface |
|
34 |
replacing the cdev. |
|
35 |
* Redundancy with 2 network adapters. |
|
36 |
* Interface/buffers for asynchronous domain IO. |
|
37 |
||
38 |
Smaller issues: |
|
39 |
||
40 |
* Datagram debugging flag. |
|
41 |
* Clear sync managers in INIT. |
|
42 |
* Simplify FSMs with <state>_enter() functions. |
|
43 |
* Read out CRC counters. |
|
44 |
* Optimize alignment of process data. |
|
45 |
* Evaluate EEPROM contents after writing. |
|
46 |
* Configure slave ports to automatically open on link detection. |
|
47 |
* Interrupt master state machines state scan for other jobs. |
|
48 |
* Master state machine, slave configuration: Do not check every slave on |
|
49 |
a cycle. |
|
50 |
* Only execute one EoE handler per EoE cycle. |
|
51 |
||
52 |
Less important issues: |
|
53 |
||
54 |
* File access over EtherCAT (FoE). |
|
55 |
* Allow VLAN tagging. |
|
56 |
* Determine number of frames, the NIC can handle. |
