- provide more directory structure for boards/targets?
- factor configurations into layers (encapsulation and re-use)
+- Fix handling of variables between multiple command line "-c" and "-f"
+ parameters. Currently variables assigned through one such parameter
+ command/script are unset before the next one is invoked.
+
- Isolate all TCL command support:
- Pure C CLI implementations using --disable-builtin-tcl.
- Allow developers to build new dongles using OpenOCD's JTAG core.
@subsection thelistjtaginterfaces JTAG Interfaces
+There are some known bugs to fix in JTAG adapter drivers:
+
+- For JTAG_STATEMOVE to TAP_RESET, all drivers must ignore the current
+ recorded state. The tap_get_state() call won't necessarily return
+ the correct value, especially at server startup. Fix is easy: in
+ that case, always issue five clocks with TMS high.
+ - amt_jtagaccel.c
+ - arm-jtag-ew.c
+ - bitbang.c
+ - bitq.c
+ - gw16012.c
+ - jlink.c
+ - usbprog.c
+ - vsllink.c
+ - rlink/rlink.c

The following tasks have been suggeted for improving OpenOCD's JTAG
interface support:
- J-Link driver:
- fix to work with long scan chains, such as R.Doss's svf test.
- FT2232 (libftdi):
- - make performance comparable to alternatives
+ - make performance comparable to alternatives (on Win32, D2XX is faster)
- make usability comparable to alternatives
The following tasks have been suggested for adding new JTAG interfaces:

- regression: "reset halt" between 729(works) and 788(fails): @par

+- ARM7/9:
+ - add reset option to allow programming embedded ice while srst is asserted.
+ Some CPUs will gate the JTAG clock when srst is asserted and in this case,
+ it is necessary to program embedded ice and then assert srst afterwards.
- ARM923EJS:
- reset run/halt/step is not robust; needs testing to map out problems.
- ARM11 improvements (MB?)
- - fix single stepping (reported by ØH). Need to automatically
+ - Single stepping works, but should automatically
use hardware stepping if available.
- hunt down and add timeouts to all infinite loops, e.g. arm11_run_instr_no_data would
lock up in infinite loop if e.g. an "mdh" command tries to read memory from invalid memory location.
