Octa core Risc V .....sbc

[vinceASPECT]

Hello forum

There are new octa core SBC computers out which are Risc v.

Each single core offers 1 point 3 times better speed than an Arm a55 cpu

and the computers are 30 bucks

They support the latest Ubuntu but I don't know if they support the repo of apps

They are a well known brand of fruit named SBC

thx
C

hope it interests people

some interesting comparison & reviews of ppl with hw @ https://old.reddit.com/r/RISCV/comments/1j6c6xz/orange_pi_rv2_riscv_sbc_powered_by_ky_x1_octacore/

Nice Thanks

they seem pretty pleased with it

Just ordered an Orange from Ali.  Thanks for the heads-up!
Eight RISC cores...  a pair of M.2...  dual Gigabit Ethernet...  this should prove to be interesting!

[vinceASPECT]

Sir / Madam,

Yes , interesting indeed. Just reading here about if RISC V Ubuntu supports all Ubuntu Repo of apps.

thx

LOL - I have no personal use for Ubuntu.
I was thinking more under the lines of Core.

[vinceASPECT]

Right.

Not sure how you would compile Tinycore for RISC V.

No doubt it's very involved.

Thx

I think graphic drivers will be bigest challenge. And I talk about simple cli display. Also bootloader.

[vinceASPECT]

YEs,

There are some open source free graphics drivers for RISC V

You should look at T2 Linux, with Rene.
https://t2sde.org/

He tries to cross compile/and native compile AMD ROCM drivers for RISC-V.

Yes,

Out of interest it says the following at Perplexity,

=========================

Will ubuntu for RISC V have a compatible app repo?

Answer


Yes, Ubuntu for RISC-V will have a compatible app repository. Canonical has been actively porting Ubuntu packages to RISC-V architecture, and as of 2025, 97–98% of Ubuntu's packages are already ported to RISC-V. This ensures robust compatibility and software availability for RISC-V platforms.

Additionally, Canonical plans to leverage the RVA23 Profile, which guarantees software portability across compliant RISC-V chips. This means that a single binary can run on all RVA23-compliant devices, further enhancing app compatibility for Ubuntu on RISC-V

=========================

so all Ubuntu's APPS work on Risc V

RV2 arrived today (in fact, I'm typing on it right now.)
I ordered the 2GB unit as I didn't want to over-invest in something that might have been a disappointment - even with only 2GB it's reasonably impressive.  It'll be even more so once I order the M.2 SATA (6 Port) adapters and see about adding half a dozen to a dozen SSDs and/or Spinners   Even MORE so once I've had a chance to check out the repo for tools to port this thing over

BUT...

Specs call for a 6 Amp 5vDC (USB-C) power supply which most people aren't going to have lying around.  I have it connected to a bench supply and it's not drawing all that much (~2A) but I'm also not overloading the existing hardware and/or adding a bunch of USB devices.

I'll have more details once I have had time to thoroughly dig in!

[CentralWare]

Sorry - typo!
Power Supply per the user manual indicates 5v 5A, not six.
HOWEVER the OEM supply is a quad voltage (5v, 9v, 12v, 15v) each having its own ratings.
Variable and bench supplies are only feeding 5v through the onboard USB-C port.

There seems to be a small (~16MB) onboard flash I'm assuming is configs, bootstrap, etc. (haven't dissected it yet!)
Micro-SD is the primary boot medium followed by eMMC and if I'm reading it correctly, followed by Gen2 M.2 2280 (the 2230 slot doesn't boot.  They say "yet.")

Running power requirements with only KB, Mouse and TF Flash connected idles around 0.6A, peaks 1.0A during boot, and I was hitting 2.1A with M.2s both populated along with a USB3 drive attached.  The manual's requirements might be a bit high.  I've given 'er a 4.0 Amp ceiling and so far she hasn't come close to hitting it.

The M.2 ports are not capable of B/M Key SATA cards (they fit, of course, but the system can't see them OR maybe support isn't in the kernel - I haven't dug yet.)

The WiFi antenna included with the unit is...  well, it's two chokes inside heat-shrink tube so it's fugly and no means to properly mount it anywhere.  A little creativity will be needed if we 3D build a mount for this board.

There are two Gigabit chips/ports founded from the USB3 bus, dual MIPI camera slots, a single MIPI video and single HDMI for those who like to see what they're doing and a micro plug for a battery to keep the onboard RTC alive.  For those who like GPIOs there's a RasPi1 header - which isn't too bad considering the number of devices already populating the board.

This board gets a little toasty at idle, so I'm guessing active cooling may be in order.

Finally, the system seems sensitive to voltage.  RasPi doesn't like running AT 5.0V - it likes a little elbow room around 5.1x volts.  Orange, however, didn't care for going past the boot-loader screen with a manual setting of 5.11v but at exactly 5.00 she's seemingly happy.  I don't know the borders yet, but they'll get documented.

Online grape-vine leads one to believe there's a WRT port, possibly a Debian one and of course, the Ubuntu 22.x that's listed on their website.
However, a number of their resources (schematic, cross-comp chain, etc.) are empty - intentionally or otherwise is yet unknown, but there's a start!  The /boot directory looks to have a config (unsure if it's complete yet) for 6.6.63 developer kernel with a notation that it's not for production and that trace_printk() is being used for debugging.

Ahh...  that's better!  SSH is now lit.
Okay, warm boot ('Buntu) is failing - freezes at boot loader screen; may be temperature related as the unit gets turned off for a few minutes and once cooled, acts normally.

These boards are still in their infancy, but thus far things look promising!

definitely interesting!

[vinceASPECT]

great

but Ubuntu is failing......what OS did you use and how did you type?

you could try DEbian and the repo of APPS
