## HEAD <a name="head"></a>
### General Proviso
The HEAD version shows the current development. No guarantees that
software or firmware builds or that the documentation is consistent.
The full set of tests is only run for tagged releases.
### Special Provisos
- DEUNA still with very limited functionality and testing
- no buffer chaining
- no loopback
- no memory access error checking
- works with 211bsd, ping and telnet login tested
- DEUNA and nexys3 shows rlink aborts
- unlikely that it's a DEUNA issue
- more likely this revealed a hidden flaw in the fx2 based transport
- all works fine with nexys4 !
### Summary
- refurbish dmcmon
- has now the sta,sto,sus,res logic as rbmon and ibmon
- does not depend on full state number generation anymore
- missed WAIT instructions so far, has been fixed
- dmcmon included in sys_w11a_n4 again
- full snum generation code gives bad synthesis under vivado (fine in ISE)
- the updated dmcmon can life with a simple, category based, snum
- integrate rbus monitor in w11 shell
- ti_rri: setup rbus monitor if detected
- rw11/shell.tcl: add .rme,.rmd,.rmf,.rml

- */util.tcl: setup: now idempotent
- w11 shell .bs now support ibus register names and ranges

- use start,stop,suspend,resume functions; improved stop on wrap handling
- add 'repeat collapse' logic (store only first and last of a sequence)
- BUGFIX: `rlc get logfile` or `rlc get *` crashed with segfault
- error was a type mismatch in the getter declaration in RtclRlinkConnect
- fixed by changing the return type in RlinkConnect
