|
|
- w11a_V0.60 -> w11a_V0.70 cummulative summary of key changes
|
|
- Bugfix for DIV instruction (in w11a_V0.61, see ECO-026-div.txt)
|
|
- revised rbus protocol V4 (in w11a_V0.62, see README_Rlink_V4.txt)
|
|
- add basic Vivado support (in w11a_V0.64)
|
|
- add Nexys4 and Basys3 port of w11a (in w11a_V0.64)
|
|
- add RH70+RP/RM disk support (in w11a_V0.65)
|
|
- add TM11/TY10 tape support (in w11a_V0.66)
|
|
- reference system now ISE 14.7, Vivado 2014.4; Ubuntu 14.04 64 bit, ghdl 0.31
|
|
|
|
- trunk (2015-06-21: svn rev 33(oc) 693(wfjm); tagged w11a_V0.70) +++++++++++
|
|
- Preface
|
|
- resolved known issue V0.66-2: operation with multiple RP or RM disks
|
|
under 211bsd works now. Issue was caused by a faulty error check.
|
|
- resolved bug tracker issue 2015-06-06: the tm11 offline function works
|
|
now as expected. Issue was caused by de-referencing a null pointer.
|
|
- resolved bug tracker request 2015-06-05: the values returned as drive
|
|
serial number were interpreted by 211bsd standalone code as a signature
|
|
of SI drives, which made disk partitioning a bit cumbersome. Changed the
|
|
scheme used to generate drive serial numbers such that they never match
|
|
these 3rd party drive characteristics. The 211bsd installation on a
|
|
RM05 is documented with the 211bsd_tm oskit.
|
|
- the w11a designs grow larger, filling the FPGA's on Nexys2 and Nexys3
|
|
to ~50% (n2) or 67% (n3). To reach timing closure without fine tuning
|
|
constraints the cpu clock had to be reduced to
|
|
sys_w11a_n2 now 52 MHz (was 54 MHz)
|
|
sys_w11a_n3 now 64 MHz (was 68 MHz)
|
|
|
|
- w11a has now a complete set of mass storage peripherals. This is a good
|
|
reason of a major release, thus go for version V0.70.
|
|
|
|
- there are many known issues, and in many cases only core functionality
|
|
used by operating systems has been implemented. The missing parts will
|
|
be implemented in the upcoming releases towards V0.80, also much more
|
|
intensive testing, especially with maindecs (aka xxdp) will be done.
