   6 @section thelist The List
   7
   8 Most items are open for the taking, but please post to the mailing list
   9 before spending much time working on anything lists here.  The community
  10 may have evolved an idea since it was added here.
  11
  12 Feel free to send patches to add or clarify items on this list, too.

  14 @section thelisttcl TCL
  15
  16 This section provides possible things to improve with OpenOCD's TCL support.
  17
  18 - Fix problem with incorrect line numbers reported for a syntax
  19   error in a reset init event.
  20
  21 - organize the TCL configurations:
  22   - provide more directory structure for boards/targets?
  23   - factor configurations into layers (encapsulation and re-use)
  24
  25 - Isolate all TCL command support:
  26   - Pure C CLI implementations using --disable-builtin-tcl.
  27     - Allow developers to build new dongles using OpenOCD's JTAG core.
  28     - At first, provide only low-level JTAG support; target layer and
  29       above rely heavily on scripting event mechanisms.
  30   - Allow full TCL support? add --with-tcl=/path/to/installed/tcl
  31   - Move TCL support out of foo.[ch] and into foo_tcl.[ch] (other ideas?)
  32     - See src/jtag/core.c and src/jtag/tcl.c for an example.
  33     - allow some of these TCL command modules to be dynamically loadable?
  34
  35 @section thelistjtag JTAG
  36
  37 This section list issues that need to be resolved in the JTAG layer.
  38
  39 @subsection thelistjtagcore JTAG Core
  40
  41 The following tasks have been suggeted for cleaning up the JTAG layer:
  42
  43 - use tap_set_state everywhere to allow logging TAP state transitions
  44 - rename other tap_states to use standard JTAG names (suggested by ML)
  45 - Encapsulate cmd_queue_cur_state and related varaible handling.
  46
  47 The following tasks have been suggested for adding new core JTAG support:
  48
  49 - autodetect devices present on the scan chain
  50   - implement 'discover_taps' command
  51 - SPI/UART emulation:
  52   - (ab)use bit-banging JTAG interfaces to emulate SPI/UART
  53   - allow SPI to program flash, MCUs, etc.
  54
  55 @subsection thelistjtaginterfaces JTAG Interfaces
  56
  57 The following tasks have been suggeted for improving OpenOCD's JTAG
  58 interface support:
  59
  60 - rework USB communication to be more robust.  Two possible options are:
  61   -# use libusb-1.0.1 with libusb-compat-0.1.1 (non-blocking I/O wrapper)
  62   -# rewrite implementation to use non-blocking I/O
  63 - J-Link driver:
  64   - fix to work with long scan chains, such as R.Doss's svf test.
  65 - FT2232 (libftdi):
  66   - make performance comparable to alternatives
  67   - make usability comparable to alternatives
  68
  69 The following tasks have been suggested for adding new JTAG interfaces:
  70
  71 - TCP driver: allow client/server for remote JTAG interface control.
  72
  73 @section thelistswd Serial Wire Debug
  74
  75 - implement Serial Wire Debug interface
  76
  77 @section thelistbs Boundary Scan Support
  78
  79 - add STAPL support?
  80 - add BSDL support?
  81
  82 A few possible options for the above:
  83   -# Fake a TCL equivalent?
  84   -# Integrate an existing library?
  85   -# Write a new C implementation a la Jim?
  86
  87 Once the above are completed:
  88 - add support for programming flash using boundary scan techniques
  89 - add integration with a modified gerber view program:
  90   - provide means to view the PCB and select pins and traces
  91   - allow use-cases such as the following:
  92     - @b Stimulus
  93       -# Double-click on a pin (or trace) with the mouse.
  94     - @b Effects
  95       -# The trace starts blinking, and
  96       -# OpenOCD toggles the pin(s) 0/1.
  97
  98 @section thelisttargets Target Support
  99
 100 - regression: xscale does not place debug_handler.bin into the right spot:

 170
 171 @section thelisttesting Testing Suite
 172
 173 This section includes several related groups of ideas:
 174 - @ref thelistunittests
 175 - @ref thelistsmoketests
 176 - @ref thelisttestreports
 177 - @ref thelisttestgenerichw
 178
 179 @subsection thelistunittests Unit Tests
 180
 181 - add testing skeleton to provide frameworks for adding tests
 182 - implement server unit tests
 183 - implement JTAG core unit tests
 184 - implement JTAG interface unit tests
 185 - implement flash unit tests
 186 - implement target unit tests
 187
 188 @subsection thelistsmoketests Smoke Test Tools
 189
 190 -# extend 'make check' with a smoketest app
 191   - checks for OOCD_TEST_CONFIG, etc. in environment (or config file)
 192   - if properly set, runs the smoke test with specified parameters
 193     - openocd -f ${OOCD_TEST_CONFIG}
 194     - implies a modular test suite (see below)
 195   - should be able to run some minimal tests with dummy interface:
 196     - compare results of baseline sanity checks with expected results
 197
 198 -# builds a more complete test suite:
 199   - existing testing/examples/ look like a great start
 200   - all targets should be tested fully and for all capabilities
 201     - we do NOT want a "lowest common denominator" test suite
 202     - ... but can we start with one to get going?
 203   - probably requires one test configuration file per board/target
 204     - modularization can occur here, just like with targets/boards/chips
 205     - coverage can increase over time, building up bundles of tests
 206
 207 -# add new 'smoketest' Makefile target:
 208   - calls 'make check' (and the smoketest app)
 209   - gather inputs and output into a report file
 210
 211 @subsection thelisttestreports Test Feedback Tools
 212
 213 These ideas were first introduced here: @par
 214   https://lists.berlios.de/pipermail/openocd-development/2009-May/006358.html
 215
 216 - provide report submission scripts for e-mail and web forms
 217 - add new Makefile targets to post the report:
 218   - 'checkreportsend' -- send to list via e-mail (via sendmail)
 219   - 'checkreportpost' -- send web form (via curl or other script)
 220
 221 @subsection thelisttestgenerichw Generic Hardware Tester
 222
 223 - implement VHDL to use for FPGA-based JTAG TAP testing device
 224 - develop test suite that utilizes this testing device
 225
 226 @section thelistautotools Autotools Build System
 227
 228 - make entire configure process require less user consideration:
 229   - automatically detect the features that are available, unless
 230     options were specifically provided to configure
 231   - provide a report of the drivers that will be build at the end of
 232     running configure, so the users can verify which driverswill be
 233     built during 'make' (and their options) .
 234 - eliminate sources of confusion in @c bootstrap script:
 235   -# Make @c bootstrap call 'configure --enable-maintainer-mode \<opts\>'?
 236   -# Add @c buildstrap script to assist with boostrap and configure steps.
 237 - automatically build tool-chains required for cross-compiling
 238   - produce mingw32, arm-elf, others using in-tree scripts
 239   - build all required target code from sources
 240 - make JTAG and USB debug output a run-time configuration option
 241
 242 @section thelistarchitecture Architectural Tasks
 243
 244 The following architectural tasks need to be accomplished and should be
 245 fairly easy to complete:
 246
 247 - clean-up code to match style guides
 248 - factor code to eliminate duplicated functionality
 249 - rewrite code that uses casts to access 16-bit and larger types
 250   from unaligned memory addresses
 251 - libopenocd support: @par
 252     https://lists.berlios.de/pipermail/openocd-development/2009-May/006405.html
 253 - review and clean up interface/target/flash APIs
 254
 255 The following strategic tasks will require ambition, knowledge, and time
 256 to complete:
 257
 258 - overhaul use of types to improve 32/64-bit portability
 259   - types for both host and target word sizes?
 260   - can we use GDB's CORE_TYPE support?
 261 - Allow N:M:P mapping of servers, targets, and interfaces
 262 - loadable module support for interface/target/flash drivers and commands
 263   - support both static and dynamic modules.
 264   - should probably use libltdl for dynamic library handing.
 265
 266 @section thelistadmin Documentation Tasks
 267
 268 - Develop milestone and release guidelines, processes, and scripts.
 269 - Develop "style" guidelines (and scripts) for maintainers:
 270   - reviewing patches
 271   - committing to Subversion
 272 - Review The Guide for OpenOCD Users for documentation errors or omissions
 273 - Update The Manual for OpenOCD Developerrs:
 274   - Add documentation describing the architecture of each module
 275   - Provide more Technical Primers to bootstrap contributor knowledge
