Do we know what instruction-set profile it implements? Any?

#62Upstreasming status: https://rvspace.org/en/new-page/JH7110_Upstream_Plan StarFive Tech. have been upstreaming on kernel, OpenSBI and U-Boot from several weeks now. Of course this is still weeks/months away (if not more, for all the features) from landing in stable releases. Even more for distributions to pick those up.

#63I have a sifive "unmatched" board sitting here collecting dust, cost me $700 then. Most projects turned out ARM based after I bought it. The site is not working, any price of this board? What's its market, e.g. ip camera? I'm still interested in lower cost ready to go risc-v boards.
I’m looking to buy these boards; recently I bought one on eBay. I plan on using them to add to FOSS projects’ buildfarms. The first one I got from eBay is now running Postgres buildfarm. Please let me know if you’re interested in selling me yours.
yes since it is no longer needed for my projects.

Any reason why it's collecting dust? I have a few RISC-V boards and I haven't had any issues with them other than having to compile almost everything from source.
mainly because my projects are now all arm
the fan on unmatched was screaming loud, i bought a quiet one and it worked well.

> 1 Processor, 1 Core, 4 Threads Any idea why StarFive went with this choice for an SBC? I remember POWER7 also having 4 SMT, but it felt right for a superscalar multi-core CPU.
The link in the GP comment is wrong - both SoCs have 4 cores, each with a single thread. The reason why this SoC is faster than HiFive Unmatched seems to be down to architectural improvements.
They both use U74, but different versions.
The one in JH7110 is the 2021Q1 version, AIUI.
Besides faster, it also added B extension.

#67I received mine weeks ago. There are several desktop images but various issues reported from no display output, to only 1080p supported. To this image or that one working. Important note, the later images require an updated to uboot and SPL, either with the bootrom or a serial connection. It's a mess at the moment!
Does is have UEFI boot support? I guess through u-boot?
AIUI it doesn't, but there's nothing in the way of it, other than some board-specific porting work.
I believe by the standard boot process, opensbi would jump into uefi instead of u-boot.

We should remind ourselves that Raspberry Pis are in abundance, just not in the hobbyist channel. Current situation is not unlike the graphics card shortage when crypto miners were on garaunteed purchase contracts This board has so much going for it. The native M.2 is a highly desireable feature. The only knock is the lack of wifi/bluetooth which can at least be solved with a dongle.
The no-wifi seems to just be the kickstarter. When I ordered mine a little while back, they had an option for wifi (extra $8-$10, as I recall). I haven't received it yet...so not sure if it actually does.
I understand it is just a usb dongle, shipped together.

4.4 W is the figure given for the SoC on full load. They also give a lower figure that's 3.x W for full load with the GPU off. It won't need a heatsink, because with its power draw it won't get above 70C even on full load, while the chip is built for industrial temperature range in operation.
Do you have a URL for those 3.xW and 4.4W claims? For longevity 60C is better. I'm talking multiple decades at constant permanent full blast here.

The interesting part goes:
>As for power consumption, JH7110 is separated into 8 independent power domains. CPU frequency can be configured through software. To achieve a balanced PPA, customers can set the most optimum SoC frequency based on their application scenarios and performance requirements. In sleep mode, the static power consumption of JH7110 is 120 mW. When working on an SBC, with all the main modules under full load, the dynamic power consumption of JH7110 is 4,100 mW. In the application scenarios of soft routers and NAS, where you don’t need GPU and video processing, but only require the dual Ethernet port operation, you can configure the modules on/off through software. And the actual power consumption decreases to 3,300 mW.
So, to summarize:
* 120mW when completely idle.
* 4100mW on full load.
* 3300mW on full load w/o GPU or video processing modules.
This is, I have to say, crazy good relative to rpi4.
>For longevity 60C is better. I'm talking multiple decades at constant permanent full blast here.
Yes, I will at least put a stick-on passive heatsink on mine.

It's sad how 'being able to actually use GPIO pins in software' is an achievement for an SBC. But I do applaud StarFive for actually seeming to throw some support behind their boards. We have been spoiled with Raspberry Pi the past few years prior to the shortages. I wish another vendor could get close to Pi's position to give more competition in terms of support and documentation.
I don’t know much about this stuff. But Khadas has some stuff. They provide quite a lot of docs. Even cad model so you can design cases for their stuff.
I just got an Edge 2. Damn so much faster than my pi4. The downside is I think it’s hard/impossible to get an OS on it other than the ones they provide. ubuntu/android.
