Fixes:
|
| 17 |
|
|
1. Modified DHCPReset() in DHCP.c to not reset DHCP state machine if it was previously
|
| 18 |
|
|
disabled using DHCPDisable(). This would make sure that if DHCP module was enabled
|
| 19 |
|
|
and application had run-time disabled DHCP and network cable is disconnected,
|
| 20 |
|
|
stack will not clear its IP address.
|
| 21 |
|
|
|
| 22 |
|
|
2. Rebuilt mib2bib.exe file with static library options. This fixes problem where
|
| 23 |
|
|
one tries to execute this exe, an error occurs about missing DLLs.
|

v2.20.03:
|
| 28 |
|
|
********
|
| 29 |
|
|
Improvements:
|
| 30 |
|
|
1. When DHCP is enabled, LINK is monitored and IP address is reset on disconnect.
|
| 31 |
|
|
New IP configuration is obtained on LINK reconnect. - For RealTek only.
|
| 32 |
|
|
Modified DHCP.c to add DHCPReset()
|
| 33 |
|
|
Modified MAC.c to add MACIsLinked()
|
| 34 |
|
|
Modified StackTsk.h to add BYTE_VAL def.
|
| 35 |
|
|
|
| 36 |
|
|
Changes:
|
| 37 |
|
|
1. Modified SMSC91c111.c to add empty MACIsLinked() - will be populated in next rev.
|
| 38 |
|
|
|
| 39 |
|
|
Bug Fixes:
|
| 40 |
|
|
1. Corrected DHCP logic to accept first DHCP offer instead of second response.
|
| 41 |
|
|
2. Corrected DHCP logic to check for chaddr in DHCP offer and accept one that
|
| 42 |
|
|
matches with local MAC address. This will fix problem where if multiple
|
| 43 |
|
|
nodes were on bus and all requested DHCP address, all would accept response
|
| 44 |
|
|
from one server instead of verifying who was intended node.
|
| 45 |
|
|
3. Fixed UDPClose() in UDP.c to use INVALID_UDP_PORT instead of INVALID_UDP_SOCKET
|
| 46 |
|
|
because of which a closed socket would not be scanned correctly.
|
| 47 |
|
|
4. Modified UDP.h to use long contsant designators for INVALID_UDP_OPRT
|
| 48 |
|
|
to explicitly state that it is a long.

v2.20.02:

********
|
| 55 |
|
|
Beta version containing TFTP client module.
|
| 56 |
|
|
|
| 57 |
|
|
Addition:
|
| 58 |
|
|
1. TFTP Client module - See TFTPc.* and TFTPcDemo.c for more information.
|
| 59 |
|
|
See MpTFTPcDemo and HtTFTPcDemo projects for build information.
|
| 60 |
|
|
|
| 61 |
|
|
Bug Fix:
|
| 62 |
|
|
1. UDPIsGetReady() was modified to overcome compiler rule where only 8-bit value was
|
| 63 |
|
|
used to evaluate non-zero condition.
|
| 64 |
|
|
2. ARPResolve() in ARPTsk was fixed to clear Cache.IPAddr value.

********

Bug fix:
|
| 70 |
|
|
1. Fixed SMSC91C111.c where MACInit() would hand if ethernet link is not detected.

v2.20:
|
| 75 |
|
|
********
|
| 76 |
|
|
Bug Fixes:
|
| 77 |
|
|
1. General - Removed most of harmless warnings.
|
| 78 |
|
|
2. C18Cfg.asm - Fixed "include" instead of "define".
|
| 79 |
|
|
3. DHCP.c - Increased DHCP_TIMEOUT_VAL to 2 seconds.
|
| 80 |
|
|
Fixed problem where UDP active socket was not set before calling UDP functions
|
| 81 |
|
|
in SM_DHCP_BROADCAST state.
|
| 82 |
|
|
4. MAC.c - Fixed MACIsTxReady() where under heavy traffic it would always return FALSE.
|
| 83 |
|
|
This fixes bug where all high level applications would stop transmitting.
|
| 84 |
|
|
5. TCP.c - Enabled portion of code that performs timeout logic even if TCP_NO_WAIT_ACK
|
| 85 |
|
|
is defined. This fixes bug where occasionally, tcp applications such as
|
| 86 |
|
|
HTTP server would stop working after few hours.
|
| 87 |
|
|
6. UDP.c - Fixed UDPGet() where it would return FALSE on last good byte.
|
| 88 |
|
|
Fixed UDPProcess() where it was calculating incorrect length.
|
| 89 |
|
|
|
| 90 |
|
|
Added bFirstRead flag with UDP sockets similar to TCP sockets
|
| 91 |
|
|
so that whenever first UDP byte is read, MAC read pointer will be
|
| 92 |
|
|
reset to begining of correct packet.
|
| 93 |
|
|
This change fixes problem where if one transmits a packet while
|
| 94 |
|
|
UDP packet is pending in a socket, next get to pending UDP socket would
|
| 95 |
|
|
return wrong data. (This is apparent only when there is heavy network traffic)
|
| 96 |
|
|
|
| 97 |
|
|
Known Issues:
|
| 98 |
|
|
1. HiTech v8.20 PL4 with all optimization enabled may not work properly.
|
| 99 |
|
|
2. C18 "Static" and "Auto" mode may not be used - there are too many local variables to fit
|
| 100 |
|
|
in standard stack of 256 bytes. One may modify linker script file to avoid this limitation.
|
| 101 |
|
|
|
| 102 |
|
|
|
| 103 |
|
|
|
| 104 |

|
Improvements:
|
| 105 |
|
|
1. Modified TICK def. in Tick.h to unsigned long to support 32-bit wide SNMP tick.
|
| 106 |
|
|
2. Added SNMP Module (SNMP.c)
|
| 107 |
|
|
3. Added Two new demo projects - DemoSNMPApp and HtDemoSNMPApp.
|
| 108 |
|
|
4. Created MPLAB 6.X projects for different demo configurations.
|
| 109 |
|
|
5. MAC.c - Added MACGetTxOffset().
|
| 110 |
|
|
6. MPFS.c - Added MPFSSeek(), MPFSTell().
|
| 111 |
|
|
7. MPFSImg.*- Rebuilt to reflect v2.20, footprint changes etc.
|
| 112 |
|
|
8. StackTsk.h- Enhanced WORD_VAL, DWORD_VAL defs.
|
| 113 |
|
|
Added STACK_USE_SNMP and related compile-time checks.
|
| 114 |
|
|
9. UDP.h - Added UDPSetTx and UDPSetRx macros.
|
| 115 |
|
|
Moved UDP_SOCKET_INFO structure to header file.
|
| 116 |
|
|
10. WebSrvr.c- Modifed MCHPStack version message and added DATE info to BoardSetup
|
| 117 |
|
|
menu.
|
| 118 |
|
|
11. Added support for SMSC LAN91C111 10/100 Non-PCI ethernet controller
|
| 119 |
|
|
Use "SMSC91C111.C" instead of MAC.c.
|
| 120 |
|
|
"mpnicee_smsc" is a sample project that uses PIC18F8720 and SMSC NIC.
|
| 121 |
|
|
"MasterDemo.c" is a main source file for above project that includes
|
| 122 |
|
|
all modules - must use device with more than 32KB of memory.

|
3. Hi-Tech Compiler:
|

| 177 |
|
|
Workaround: Apply optimization listed in each source file comment header.
|
| 178 |
|
|
2. In order to use V8.12, you will need to remove "FTP Server" from Ht*.pjt.
|
| 179 |
