it works the same as the rpi, no?
if so, probably yes.
burn the .img into an sdcard and try it out. report back any the results.

But is it possible to assemble ISO from under Plan 9? Purely from the
system itself? Of course. I will tell you the results as soon as the
Raspberry Pi Zero arrives.

The current SD card image https://9p.io/sources/contrib/miller/9pi.img.gz
has a flaw in the bootable kernel which makes it wait forever for a
usb ethernet adapter, which isn't there on the pi zero. So, after burning
the SD card, please copy https://9p.io/sources/contrib/miller/9pi to the
DOS partition - this is a newer kernel which fixes the problem.
I will get around to updating the 9pi.img.gz Real Soon Now.

Cool. Thank you very much)) It is very pleasing. By the way, in plan 9, are
things with RISC-V?

I have a working (but not very thoroughly tested) plan 9 C compiler,
assembler, and loader for RV32IM.
I believe there was a Harvey OS version for RISC-V -- does anyone
have up to date info about that?

Do you mean something like BlackIce II (I'm under RV32I)? There is still
one interesting board (inexpensive) on the RISC V 64 bit (RV64IMAG) - if
you want I will show where to get

Yes, I have tried various soft cores on BlackIce (including
one of my own design, for fun); also real silicon HiFive-1.
So far none of these has had an MMU, which is required for
Plan 9 (though not for Inferno).

that is, blackice II will not start? (yes, by the way, how small the world

Speaking of RISC-V with MMU for Plan 9, Kendryte K210 is a 28nm MCU
with dual core RV64GC and Linux capable MMU (!). It has 8MB onchip
SRAM and also NN, FFT accelerators.
I think that makes a good platform for Plan 9 on RISC-V, on a real silicon.
It also has a lot of really cheap evaluation board options available.
(The only other currently available RV64GC w/ MMU silicon is the
Hifive unleashed, which is very expensive.)
The only major problem of K210 is that its IO capabilities are fairly
limited and you need external Ethernet/Wifi solutions on SPI bus,
which is likely slow.

By the way, I meant kendryte k210. and the board, for example, maix bit, is
very cheap (you can get a stock from Bangood.com)

I think it should be possible to add an MMU to a small RISC-V core
(eg picorv32) to fit on BlackIce II or MX, but I haven't tried
it myself.
You would also need some external RAM. I've been experimenting with
an 8MB hyperram chip, which is enough for bootstrapping the C compiler
in a "bare metal" setting, but a full Plan 9 would need lots more.

Thanks guys. Replacing 'www' with my country code shows me it's pretty cheap.

Has anyone tried putting Plan 9 on one of these MIPS based SoC’s?
https://vocore.io/v2u.html
The hardware is supposedly open, which might make it easier to work on drivers.
