/** @page tasks Pending and Open Tasks
|
||
|
||
This page lists pending and open tasks being considered or worked upon
|
||
by the OpenOCD community.
|
||
|
||
@section thelist The List
|
||
|
||
Items with a current patch available should include a link to its
|
||
posting on the openocd-developer mailing list archives.
|
||
|
||
Some items may be in progress, usually indicated by the individual whose
|
||
initials in parentheses following it. A key for decoding these initials
|
||
appears after The List.
|
||
|
||
Most items are open for the taking, but please post to the mailing list
|
||
before spending much time working on anything lists here. The community
|
||
may have evolved an idea since it was added here.
|
||
|
||
Feel free to send patches to add or clarify items on this list, too.
|
||
|
||
@section thelisttcl TCL
|
||
|
||
This section provides possible things to improve with OpenOCD's TCL support.
|
||
|
||
- organize the TCL configurations:
|
||
- provide more directory structure for boards/targets?
|
||
- factor configurations into layers (encapsulation and re-use)
|
||
|
||
- Isolate all TCL command support:
|
||
- Pure C CLI implementations using --disable-builtin-tcl.
|
||
- Allow developers to build new dongles using OpenOCD's JTAG core.
|
||
- At first, provide only low-level JTAG support; target layer and
|
||
above rely heavily on scripting event mechanisms.
|
||
- Allow full TCL support? add --with-tcl=/path/to/installed/tcl
|
||
- Move TCL support out of foo.[ch] and into foo_tcl.[ch] (other ideas?)
|
||
|
||
@section thelistjtag JTAG
|
||
|
||
This section list issues that need to be resolved in the JTAG layer.
|
||
|
||
@subsection thelistjtagcore JTAG Core
|
||
|
||
The following tasks have been suggeted for cleaning up the JTAG layer:
|
||
|
||
- use tap_set_state everywhere to allow logging TAP state transitions
|
||
- rename other tap_states to use standard JTAG names (suggested by ML)
|
||
|
||
- retire jtag_add_end_state() and replace w/global variable:
|
||
- removes TAP_INVALID as an argument to jtag_add_xxxx().
|
||
|
||
- global variable as argument to jtag_add_xxxx() should be phased out,
|
||
but it is useful while we need to bug-by-bug compatible while
|
||
testing changes.
|
||
|
||
- Suggested by <20>H. Michael Bruck also interested in this.
|
||
- Encapsulate cmd_queue_cur_state and related varaible handling.
|
||
|
||
The following tasks have been suggested for adding new core JTAG support:
|
||
|
||
- autodetect devices present on the scan chain
|
||
- implement 'discover_taps' command
|
||
- SPI/UART emulation:
|
||
- (ab)use bit-banging JTAG interfaces to emulate SPI/UART
|
||
- allow SPI to program flash, MCUs, etc.
|
||
|
||
@subsection thelistjtaginterfaces JTAG Interfaces
|
||
|
||
The following tasks have been suggeted for improving OpenOCD's JTAG
|
||
interface support:
|
||
|
||
- rework USB communication to be more robust. Two possible options are:
|
||
-# use libusb-1.0.1 with libusb-compat-0.1.1 (non-blocking I/O wrapper)
|
||
-# rewrite implementation to use non-blocking I/O
|
||
- FT2232 driver:
|
||
- integrate FTD2XX High-Speed Device support @par
|
||
PATCH: https://lists.berlios.de/pipermail/openocd-development/2009-April/005479.html
|
||
- fix outstanding bugs
|
||
- J-Link driver:
|
||
- fix to work with long scan chains, such as R.Doss's svf test.
|
||
- fix other outstanding bugs
|
||
|
||
The following tasks have been suggested for adding new JTAG interfaces:
|
||
|
||
- TCP driver: allow client/server for remote JTAG interface control.
|
||
|
||
@section thelistswd Serial Wire Debug
|
||
|
||
- implement Serial Wire Debug interface
|
||
|
||
@section thelistbs Boundary Scan Support
|
||
|
||
- add STAPL support?
|
||
- add BSDL support?
|
||
|
||
A few possible options for the above:
|
||
-# Fake a TCL equivalent?
|
||
-# Integrate an existing library?
|
||
-# Write a new C implementation a la Jim?
|
||
|
||
Once the above are completed:
|
||
- add support for programming flash using boundary scan techniques
|
||
- add integration with a modified gerber view program:
|
||
- provide means to view the PCB and select pins and traces
|
||
- allow use-cases such as the following:
|
||
- @b Stimulus
|
||
-# Double-click on a pin (or trace) with the mouse.
|
||
- @b Effects
|
||
-# The trace starts blinking, and
|
||
-# OpenOCD toggles the pin(s) 0/1.
|
||
|
||
@section thelisttargets Target Support
|
||
|
||
- general layer cleanup:
|
||

http://bdm.sourceforge.net/
|
||
|
||
or the OSBDM package @par
|
||
http://forums.freescale.com/freescale/board/message?board.id=OSBDM08&thread.id=422
|
||

||
|
||
- factor and clean-up code
|
||
- review The Guide for OpenOCD Users for documentation errors or omissions

|
||
- provide Technical Primers to bootstrap contributor knowledge
|
||
- develop SVF unit tests
|
||
- develop XSVF unit tests
|
||
|

@section thelistdebug Debugger Support
|
||
|
||

|
||
|
||
@section thelisttesting Testing Suite
|
||
|
||
This section includes several related groups of ideas:
|
||
- @ref thelistunittests
|
||
- @ref thelistsmoketests
|
||
- @ref thelisttestreports
|
||
- @ref thelisttestgenerichw
|
||
|
||
@subsection thelistunittests Unit Tests
|
||
|
||
- add testing skeleton to provide frameworks for adding tests
|
||
- implement server unit tests
|
||
- implement JTAG core unit tests
|
||
- implement JTAG interface unit tests
|
||
- implement flash unit tests
|
||
- implement target unit tests
|
||
|
||
@subsection thelistsmoketests Smoke Test Tools
|
||
|
||
-# extend 'make check' with a smoketest app
|
||
- checks for OOCD_TEST_CONFIG, etc. in environment (or config file)
|
||
- if properly set, runs the smoke test with specified parameters
|
||
- openocd -f ${OOCD_TEST_CONFIG}
|
||
- implies a modular test suite (see below)
|
||
- should be able to run some minimal tests with dummy interface:
|
||
- compare results of baseline sanity checks with expected results
|
||
|
||
-# builds a more complete test suite:
|
||
- existing testing/examples/ look like a great start
|
||
- all targets should be tested fully and for all capabilities
|
||
- we do NOT want a "lowest common denominator" test suite
|
||
- ... but can we start with one to get going?
|
||
- probably requires one test configuration file per board/target
|
||
- modularization can occur here, just like with targets/boards/chips
|
||
- coverage can increase over time, building up bundles of tests
|
||
|
||
-# add new 'smoketest' Makefile target:
|
||
- calls 'make check' (and the smoketest app)
|
||
- gather inputs and output into a report file
|
||
|
||
@subsection thelisttestreports Test Feedback Tools
|
||
|
||
These ideas were first introduced here:
|
||
https://lists.berlios.de/pipermail/openocd-development/2009-May/006358.html
|
||
|
||
- provide report submission scripts for e-mail and web forms
|
||
- add new Makefile targets to post the report:
|
||
- 'checkreportsend' -- send to list via e-mail (via sendmail)
|
||
- 'checkreportpost' -- send web form (via curl or other script)
|
||
|
||
@subsection thelisttestgenerichw Generic Hardware Tester
|
||
|
||
- implement VHDL to use for FPGA-based JTAG TAP testing device
|
||
- develop test suite that utilizes this testing device
|
||
|
||
@section thelistautotools Autotools Build System
|
||
|
||
- investigate fixes to permit the use of -Wshadow
|
||
- eliminate sources of confusion in @c boostrap script:
|
||
-# Make @c bootstrap call 'configure --enable-maintainer-mode \<opts\>'?
|
||
-# Add @c buildstrap script to assist with boostrap and configure steps.
|
||
- automatically build tool-chains required for cross-compiling
|
||
- produce mingw32, arm-elf, others using in-tree scripts
|
||
- build all required target code from sources
|
||
- make JTAG and USB debug output a run-time configuration option
|
||
|
||
@section thelistarchitecture Architectural Tasks
|
||
|
||
The following architectural tasks need to be accomplished and should be
|
||
fairly easy to complete:
|
||
|
||
- factor code to eliminate duplicated functionality
|
||
- overhaul use of types to improve 32/64-bit portability
|
||
- rewrite code that uses casts to access 16-bit and larger types
|
||
from unaligned memory addresses
|
||
- libopenocd support: @par
|
||
https://lists.berlios.de/pipermail/openocd-development/2009-May/006405.html
|
||
- review and clean up interface/target/flash APIs
|
||
|
||
The following strategic tasks will require ambition, knowledge, and time
|
||
to complete:
|
||
|
||
- Allow N:M:P mapping of servers, targets, and interfaces
|
||
- loadable module support for interface/target/flash drivers
|
||
|
||
@section thelistadmin Administrative Tasks
|
||
|
||
- Develop "style" guidelines for committing to Subversion
|
||
- Develop milestone and release guidelines.
