The family of 64 bits ciforths has now a new member. https://home.hccnet.nl/a.w.m.van.der.horst/lina.html

Apart from i86 linux, MS-windows, arm Linux, and i86 Apple there
is now a risc-V version.
Due to the generic build system, this baby is born with hair, claws
and teeth.
It builds locally with the regular tool chain on a
Linux ubuntu 5.19.0-1007-allwinner #7~22.04.1-Ubuntu
SMP Wed Feb 22 16:07:52 UTC 2023 riscv64 riscv64 riscv64 GNU/Linux
and a
DongshanNeZha-STU board.

So it has the usual features of ciforth's:
1. A comprehensive test succeeds
2. Fitting documentation available in info pdf and ps format
with indices of words and concepts.
Heavily cross referenced .html present.
Man page present.
3. The library, with numerous ciforth facilities
4. Simple examples.
5. Compiles to executables. Scripting available.

Fitting means that the documentation is fully applicable to
this Forth, there are only words in the documentation that are
actually available and all words are documented the way they
actually work in this particular Forth.
(Try `` man as '' to appreciate this.)
The documentation is grouped in wordsets with a description.
This cuts down in finding a functionality (that e.g. naturally belongs
to string handling) and more importantly allows to decide whether a functionality is not available.

This is a beta release, a dated snapshot, so you will have to manually
-unpack it,
-if you're paranoid inspect the source and reassemble it;
you need gcc (actually as and ld)
-tryout: it is usable in this directory
- install : you can do a system wide install with option -i
- enlarge : if 2 Mbyte is to small use option -g
- copy .info .pdf .ps man.1 to appropriate places.

After a burn in period this will be promoted to version 5.4.

(Building a .deb archive is postponed till then. This is
as much effort as porting to risc-V in the first place.)

The word VMA-IO works, i.e. you can find the address of the io-space.
If I can locate the 1400 page (chinese?) manual of the D1-H chip,
all the gpio, dac, SPI, UARTs, timers can be used.
[ Beware: Other boards have different manuals.]

A welcome addition, thanks. I'm hoping to move my home computing to a
RISC-V soon.

To unleash the full power of the D1-H chip you need the manual
that describes the port address, functions of each ports etc.
Once you have a D1-H chip there is one variable that determines
where the ports are mapped. This available in ciforth through
the word VMA-IO . You have to be superuser, otherwise you get
a privilege violation.

I have tracked it down:
https://open.allwinnertech.com/#/doc?menuID=2
You may need to register, I did it a long time ago.
You need D1-H_UserManual_V.1.3 , but I recommend to
select all, down load all.
No it is not an excerpt, it runs 1400 pages. It is all about
hardware, look elsewhere for the instruction set/ assembler manuals.

The holding board has a mask that contains the io pins names,
e.g. PB6. These can be tracked down easily in the manual.
The circuit description is available, electronics schematics
and board layout.

The board that I have is available through analoglamb.com ,
a knowledgeable supplier which can be contacted directly and
responds.
It is shipping directly from China, no intermediate amazon or aliexpress.
