Some clarification about the cores:
- When in the Debian or Ubuntu build, your userland is running on the 1.6GHZ C908 core with all the goodies it has. The smaller core does nothing AFAIK.
- When in the MicroPython build, your busybox shell is running on the 800MHz core, with RTSmart (as shown by its shell `msh`) running MicroPython (via repl) on the big core.
- When in the C build, same as MicroPython, but you're just at the msh prompt.
More info coming, just give me a week or two! (inc power consumption)

I really like this as a motherboard for some sort of Cyberdeck build. You can run a decent Linux environment on the main core and have a little micro controller / micro-python environment ready to go for running specialized I/O or just extra stuff you don't want directly touching the main OS.

I'll not mislead myself into thinking the RiscV will get similar performance, but for sure its not useles. I have absolutely no need for this but to try build of a mock industrial controller😂

Awesome that you got one as it's cool little board. I believe Bananapi have announced their own RVV 1.0 board but no pricing as yet - Banana Pi BPI-F3 with K1 chip. Did you also see Sipeed released their own version of the Milk-V Duo S called the NanoRv with smaller footprint which is exciting as the more RISC-V boards the better!

@alexlovett1991 5 месяцев назад

Very interesting bit of kit! Are you able to program the second core from the initial core? I.e once it’s in the field it can be updated.

@PlatimaTinkers 5 месяцев назад

Yeah to a degree - depends how good you are! The two can communicate, so if you wrote custom code for each, you can pass messages between them. But as far as updating in the field you would likely a) use the MicroPython build and push code onto the big core to run, else b) use the C build and put a file with a known name in /sharefs after reconfigure RTSmart to execute that known binary name in a loop. That being said, if you're really good at editing the device tree you can probably setup the UART output from the big core to present as a COM port to the small core, instead of mapping it to the USB port, and then just treat the big core like a serial-networked computer. Not sure about restarting the 2nd core, but I would expect there is a way!

@saketsinha89 5 месяцев назад

what about the main feature that this board is specail for . Vector extensions ? No demo for that ?

@PlatimaTinkers 5 месяцев назад

Unfortunately there's no real way to show that off. Most things don't support RVV 1.0.0 yet, eg Geekbench and similar benchmarks. RVV 0.7.1 as implemented in most RISC-V SBCs the last few years should perform much the same as RVV 1.0.0, but this design is now 'stable'. That means that software can actually start adding support for the RISC-V vector extensions, which going forward makes a huge difference. If you know of any way to show it off I would gladly show it in a 'Part 2', eg putting this side-by-side with a JH7110. Cheers!

Problem with Kendryte is that there is basically no documentation, just a SDK. It was already the same issue with the K210. What they call the "K230 full datasheet" is just a 27-page product brief. Unless, of course, I missed some documentation - in that case, I'd be happy to have a look!

@PlatimaTinkers 10 дней назад

Yeah it took me bloody ages but eventually I found github.com/kendryte/k230_docs/blob/main/README_en.md Between that and www.remlab.net/op/k230-canmv-debian.shtml I got there eventually!

@joseoncrack 10 дней назад

@@PlatimaTinkers Thanks. Unfortunately, it's mostly SDK documentation (which is better than nothing as the K210 didn't even have a doc for the SDK IIRC) and hardware design guide, but no real datasheet (it's a brief) and no reference manual. So, still the usual with Kendryte. Note that it's a relatively common issue among vendors for this kind of SoCs. You're supposed to use them as you're being told to and not try to use them any other way. Haven't looked at the SDK source code though, so maybe it's clean enough that figuring out most things may not be that hard.

@PlatimaTinkers 9 дней назад

@@joseoncrack It is actually all in there, but you have to dig a fair bit. The link structure and hierarchy makes no sense. Eg this one has a fair bit: github.com/kendryte/k230_docs/blob/main/en/01_software/board/examples/K230_SDK_CanMV_Board_Demo_User_Guide.md Looking at my history, I also used developer.canaan-creative.com/k230/dev/zh/00_hardware/K230_datasheet.html#feature which appears to have full specifications, and then developer.canaan-creative.com/k230_canmv/main/index.html which the orig docs link to, and you just need to use the 'Translate to English' function as I don't think there is an English copy. But yeah, not awesome that's for sure

@BensProgrammingLab 4 месяца назад

hey I got the board but I could not figure out how to get wifi working on the small core. Any tip? But I really enjoyed watching your video! Very Interesting channel!

@PlatimaTinkers 4 месяца назад

Hey thanks mate much appreciated, and so yeah this is a bit of an odd/interesting one you raised! The default image, from memory, runs on the big core, so the little core is left doing nothing. In the MicroPython build, your Linux environment is on the little core, with FreeRTOS running on the big core. Both should have access to the AP6212 depending on the DTB file included. I didn't get wifi going personally, but I can only imagine if you dig through the device trees you should be able to find something. That being said, Rémi (www.remlab.net/op/k230-canmv-debian.shtml) didn't get it going either. Might see what Bruce Holt gets from it, and let you know if he had any luck. Mine K230 is back out at the lab somewhere as I've been messing with the BeagleV-Fire last few weeks instead.

@PlatimaTinkers 4 месяца назад

I can assemble and execute none-vector instructions just fine, but the assembler errors if I try to assemble vector instructions. I would have thought I could still assemble though (even if I was running on the smaller core), even if I couldn't execute the resulting binary. Maybe the error I'm getting is somewhere else. I'll likely post a query on the RISCV reddit over the next couple of days. :-) Thanks again.

So, could this thing run a desktop environment and function somewhat like a Raspberry Pi? I can get one for quite cheap but running standard Linux programs is kind of a requirement for me. It seems to be the cheapest RISC-V "computer" available. Also, could you get the HDMI to work as a proper video out and the USB port as an actual USB port for the OS?

@PlatimaTinkers 3 месяца назад

Nah it's more of a proof of concept than to be used like that. It's I don't think the ports are designed to be used by an OS like that either, as I don't think it has a GPU in the traditional sense. It's more of a "devboard" than most devboards really, but it's the first to show off RVV 1.0 As far as wanting an RV64 computer for desktop use, the upcoming Milk-V Meles, in SBC format, or the Oasis or Pioneer desktop boards, look excellent, but for now there is also the Milk-V Mars, which I quite like and have made a video about. There is also the StarFive VisionFive 2, which I made a video about, but has a bit of work to be done. Else the Lichee Pi 4A seems dang powerful, but I've not actually tested one yet!

Both fairly affordable, and there are even higher-end models than the Rock 4SE, but that's the one I have and like. Just the Radxa images are a bit rubbish, so you'd likely need to build your own. Else anything with the new SG2000 or SG2002 is both RISC-V and ARM in one (not at the same time), eg Milk-V Duo 256, albeit only 1-2 core, not quad, and no HDMI.

At least from the benchmarks on their website, they claim resnet50 with 65FPS while a raspberry pi 5 can do around 5 FPS, so it's not that bad if it's true.
