|
|
- Summary
|
|
- migrate to rlink protocol version 4
|
|
- Goals for rlink v4
|
|
- 16 bit addresses (instead of 8 bit)
|
|
- more robust encoding, support for error recovery at transport level
|
|
- add features to reduce round trips
|
|
- improved attention handling
|
|
- new 'list abort' command
|
|
- For further details see README_Rlink_V4.txt
|
|
- use own C++ based tcl shell tclshcpp instead of tclsh
|
|
|
|
Notes:
|
|
1. rlink protocol, core, and backend are updated in this release
|
|
2. error recovery in backend not yet implemented
|
|
3. the designs using rlink are still essentially unchanged
|
|
4. the new rlink v4 features will be exploited in upcoming releases
|
|
|
|
- New reference system
|
|
The development and test system was upgraded from Kubuntu 12.04 to 14.04.
|
|
The version of several key tools and libraries changed:
|
|
linux kernel 3.13.0 (was 3.2.0)
|
|
gcc/g++ 4.8.2 (was 4.6.3)
|
|
boost 1.54 (was 1.46.1)
|
|
libusb 1.0.17 (was 1.0.9)
|
|
perl 5.18.2 (was 5.14.2)
|
|
tcl 8.5.15 (was 8.5.11)
|
|
sdcc 3.3.0 (was 2.9.0)
|
|
doxygen 1.8.7 {installed from sources; Ub 14.04 has 1.8.6}
|
|
|
|
Notes:
|
|
1. still using tcl 8.5 (even though 8.6 is now default in Ub 14.04)
|
|
2. sdcc 3.x is not source compatible with sdcc 2.9. The Makefile
|
|
allows to use both, see tools/fx2/src/README.txt .
|
|
3. don't use doxygen 1.8.8, it fails to generate vhdl docs
|
|
|
|
- New features
|
|
- new environment variables TCLLIB and TCLLIBNAME. TCLLIBNAME must be
|
|
defined, and hold the library name matching the Tcl version already
|
|
specified with TCLINC.
|
|
- new modules
|
|
- rtl/vlib/comlib/crc16 - 16 bit crc generator (replaces crc8)
|
|
- tools/src/tclshcpp/* - new tclshcpp shell
|
|
|
|
- Changes
|
|
- rtl/vlib/comlib
|
|
- byte2cdata,cdata2byte - re-write, commas now 2 byte sequences
|
|
- rtl/vlib/rlink
|
|
- rlink_core - re-write for rlink v4
|
|
- rtl/*/* - use new rlink v4 iface and 4 bit STAT
|
|
- rtl/vlib/rbus/rbd* - new addresses in 16 bit rlink space
|
|
- rtl/vlib/simlib/simlib - add simfifo_*, wait_*, writetrace
|
|
- tools/bin/
|
|
- fx2load_wrapper - use _ic instead of _as as default firmware
|
|
- ti_rri - use tclshcpp (C++ based) rather tclsh
|
|
- tools/fx2/bin/*.ihx - recompiled with sdcc 3.3.0 + bugfixes
|
|
- tools/fx2/src/Makefile - support sdcc 3.3.0
|
|
- tools/src/
|
|
- */*.cpp - adopt for rlink v4; use nullptr
|
|
- librlink/RlinkCrc16 - 16 crc, replaces RlinkCrc8
|
|
- librlink/RlinkConnect - many changes for rlink v4
|
|
- librlink/RlinkPacketBuf* - re-write for for rlink v4
|
|
- tools/tcl/*/*.tcl - adopt for rlink v4
|
|
- renames:
|
|
- tools/bin/telnet_starter -> tools/bin/console_starter
|
|
|
|
- Bug fixes
|
|
- tools/fx2/src
|
|
- dscr_gen.A51 - correct string 0 descriptor
|
|
- lib/syncdelay.h - handle triple nop now properly
|
|
|
|
- Known issues
|
|
- rlink v4 error recovery not yet implemented, will crash on error
|
|
- command lists aren't split to fit in retransmit buffer size
|
|
{both issues not relevant for w11 backend over USB usage because the
|
|
backend produces proper command lists and the USB channel is error free}
|
|
- the rbus monitor (rbd_rbmon) not yet handling 16 bit addresses and
|
|
therefore of limited use
|
|
|
|
- trunk (2014-08-08: svn rev 25(oc) 579(wfjm); tagged w11a_V0.61) +++++++++++
