Which board to support?

[PDP-8]

Re: Asus Tinkerboard - if you don't have one already, you may want to wait for the "S" model supposedly arriving any day now.  16gb onboard emmc, better voltage regulation (although most still recommend going through gpio pins and not microusb etc....

Thing is - even with my Libre board, these boards are coming out so fast and furious, it's almost impossible to recommend one!

The good thing for bmarkus is that RPI support here fills a good niche, since the Armbian folk won't touch an RPI -- they've got their hands full among all the other boards...

Supporting Odroid C4 would be awesome !!!! Still waiting HARD for it.......

I still haven't converted my Libre Computer board (Le Potato) over from Armbian to Tinycore yet.

Just mentioning it, because unlike the RPI's being hard to find, or price-gouged online, the Libre Computer S905X-CC is still about the same price I paid online years ago and available.

Just a thought for the intrepid TC pioneers still waiting for supply chain issues to resolve with RPI's, who might something to hack on.

Yes Sir,

there are hundreds of different "SBC brands"  out there.

....a good Value for money brand are "Orange Pi". which i believe
are available  (i think they have about 16 board variants)

Hi Béla and all,
The Olimex products are of interest to me. They seem to be pro open source as much as possible.
I have not had any experience dealing with them and I have no idea about the quality but they tend to
incorporate some neat features in the OLinuXino designs.

I am saving up for a purchase, hopefully soon.
If I get an extra one, and send it to you,  would you be interested in getting it working with tiny core?

I agree for Olimex. Boards are cheap and obey healthy design principles. Software is open-source and I did read some U-boot code and it is healthy, too.

Is there other interested tc developers to fork with Olimex?

Besides, company owner Tsvetan is great innovator:

Maybe look into RISC-V architecture, now that the boards are becoming cheaper....

Is there a board for that?

....this?

There are a few suggestions on Debian's RISC-V Wiki page. I'm not sure if it's up to date though.

I just picked up an X86_64 Radxa X2L (celeron J4125), and it's mating heatsink and fan.  Has the RPI 2040 controller chip which one can use perhaps micro-python, thonny or the like.

Runs TCpure64 just fine.

Radxa makes a higher-powered X4 (N100 cpu), and I've been told to make sure there is not an air-gap between the cpu and heatsink.

So kind of hybrid X86_64 and RPI controller SBC computers.

they have some interesting products

@Béla,

+1 for OrangePi (RiscV and ARM both!)

I purchased a couple of the OrangePi RiscV boards but haven't had the time to really get my hands dirty with them yet as much as I would like.  (I did design/build an mITX adapter and case and have tested 6x SATA SSD drives with MDADM but other projects tore me away before much else was accomplished.)

I bought this one:

https://webstore.vlsi.fi/epages/vlsi.sf/en_GB/?ObjectPath=/Shops/2015020901/Categories/%22Circuits%20and%20KITs%22/VSRV

They are audio IC experts, and I suppose this is first "general industrial use" -SOC. Phone codecs are very real time performance critical applications, so they know how to handle linux real time problems.

I think RISC-V MMU is unnecessary complicated, but simplifications need support from linux kernel and RISC-V development groups. I think kernel development and RISC-V groups like tc professional minimalistic approach and efficient code,  so I suppose, that support is possible if tc-port is considered...

...and with MMU-development linux problematic device driver mechanism updates automatically, too.

I received yesterday VLSI Solutions RISC-V32 CAT Board (VSRVE01). Very fast delivery, it ready for tc port right now.

At first glance this stuff is very pro, it is targeted  for mobile phone android coders, and documentation is very minimal and good. I suppose, linux kernel is installed in "raw format" and single core.

There is another operating system on board for codec, but  I think linux side can be operated stand alone.

There is discussion forum:

https://www.vsdsp-forum.com/phpbb/index.php

..and product pages

https://www.vlsi.fi/en/products/vsrves01.html

Unfortunatelly there might be some privilegies set for these pages.

I can recommend this board for tc port, is is very minimalistic and very professionally documented.

Kernel ver. 6.12 has some very interesting RT-features:

https://kernelnewbies.org/Linux_6.12

Interrupt handlers are in kernel thread etc.:

https://www.linutronix.de/videos/introduction-to-realtime-linux.mp4?m=1586192378&

That VLSI Solutions board uses currently 6.1, but natural goal is 6,12 with RT.
