Here I show you what the parts of it are, how to flash it with the Linux image, how to gain SSH access to it, how to monitor it booting over serial, and then how to cook it with a DIY janky 24V POE adapter that faulted.
Should I build my own image for this with ION RAM already freed up, SDIO1 preconfigured for wifi, dhclient installed, and similar? Let me know in the comments!

@der.Schtefan 7 месяцев назад

So, how DO you wire up Ethernet then? :) I remember there are actual ethernet sockets, that come with the transformer already included inside. I vaguely remember it from a project that bit banged ethernet with a microcontroller in software. Also, is there any documentation on the Linux interface when it comes to the 2 ADCs?, or how to run Linux and RTOS on the two cores in parallel?

@PlatimaTinkers 7 месяцев назад

The ethernet DOES work like that, I had it working, however, you're best to 1) not use 24V passive POE like I did, and 2) use diodes on the TX/RX lines to prevent any stray signals causing issues. The ethernet module itself is super basic: www.aliexpress.us/item/3256805730788067.html The second core is still under embargo it seems, much like the issues with the BL808 on the Ox64, which essentially has the same silicone. As for the ADC though, that should either be available natively if configured in with the kernel build, which I'd expect so, else I'd say you can use pinmux to set the channel/pin mode and generate some sample sample code.

@bastiannenke9613 8 месяцев назад

This video planted the seed and i just ordered 6 of them before they go out of stock again. The Ram will probably be a issue but they'll be nice to play with until the milk-v mars is available. For less than 5€/piece they are more attractive than a microcontroller.

RISC-V is a very, very serious game changer. Coming back from a 10 year hiatus due to burnout in the PC game... In which i did not keep up with at all, absolutely blew my fkn mind man. I left when the original RPi was still struggling to get support outside of the foundation's own work and remember thinking to myself that "SBC's" were a cool idea, but the hardware would never actually allow them to become anything worth a shit. Boy, was I wrong. These new SBC's and even the RISC-V boards are just completely insane to me. I would have never ever thought these things would exist back when I was a teen and struggling to get over 500 mb of RAM for my Win 98 SE machine lol. I absolutely love this new world of computing and have spent several thousands of dollars on snatching up every SBC I could get my hands on before the good ol pandemic took a shit on the whole world. I'm still trying to catch back up with this new massive wave of product releases. 😅

Hah man I was kind of similar. Did not touch a Raspberry Pi or anything ARM or RISC-V really until about 6 years ago and was then like 'wait, I need a rack of these' haha. Win 98 SE?

@ericlawrence9060 8 месяцев назад

yes it is CRAZY. I'm gonna petition this fine youtuber to make a truly useful video we should all pitch him ideas. I want one on a plant sensor that you can use in houseplants that links to preexisting sensor apps. I think I'll put the script together for him and shoot him some cash and money to do it. these things are so amazing yet NOBODY puts sensible projects together. Think a plant stick that you shove in the ground and it tells you the LIGHT (in the plant wavelengths), the total light, and possibly moisture at different levels. so like a rod you knock in the ground 2 feet, so you don't waste water. A nutrient sensor could be good too. The thing is the prebuilt ones suck. use standard sensors. May be too hard but temp / light / water is easy but would be very very nice. Even a camera could easily be added even on a $5 ESP board like my former tech built in like 30 min off a pile of pi's and esp boards i am too lazy to work with. Sounds like you are a crack addict on this new tech like I am. i just sent him a paltry $33.33 AUS as a thank you for this. I love his coverage of the pins... ethernet 10/100... are you kidding me HOLYY SHITTT. Then he does the POE. Security cam, moisture sensor, poe, wind, sound, security, blinky light built in to scare away the fucking rabbits, and a buzzer!

I have got pH sorted in my testing, but nutrients are super hard to track, as you'd normally measure EC or TDS, but when it's soil and not hydroponics that is way harder.

PIO will not easily happen. RPi has PIO instruction set and architecture patented. Some Bouffalo chips actually have them, but due to patent issues, they were blocked at factory. WiFi is possible, more likely with a Bouffalo chip as they already have the technology on some of their chips. I know a Chinese team is working on a 32-bit PIO design (OG RPi PIO is 16-bit) that circumvents all RPi patents, but the state machine code will not be binary compatible, instead they will be offering compilers that is source compatible with RPi's.

This is a general linux question.. maybe someone can give me a pointer.. I have a USB to LAN/RJ45 adapter and a driver for it, qop_kernel/drivers/net/usb /dm9620.c But how do I compile/load it such that my pi sees it, and I can call the functions from that driver?

@PlatimaTinkers 7 месяцев назад

Hey the easiest way these days would be to build the driver using DKMS then install it. The kernel would be the one calling the driver functions, but you can also link against it in your code and include it's header if you want to call functions from your own program. Here's a really good simple guide on building a driver with DKMS that should hopefully help jksinton.com/linux/building-a-linux-kernel-driver-on-ubuntu-using-dkms/ THAT BEING SAID, USB-to-Ethernet is pretty standardised these days, and honestly I've not seen a Type A or Type C adapter in a very long time that I cannot just plug in and use. If you do `dmesg -W` keep an eye on what comes up when you plug it in, and if you've installed net-tools package you can run `ifconfig` to see all of your interfaces nicely, else `ip link show` gives you some broad strokes. Best of luck mate

That is pretty impressive. I guess, they partition RAM statically in firmware. Because website, and boot loader says there is 64MB, but only 32 or so available to the first core. I hope it will be possible to just run dual core Linux, with RTOS. It is also cool they opted for 64 bit core, instead of 32 bit one. 32MB is really low, but still probably usable, if you optimize things. The kernel they are running is also really old. I hope it will all be upstreamed properly, otherwise it will be another crap. Other than that, at that price, it is really cool.

@PlatimaTinkers 8 месяцев назад

Hey yeah it's right here, reserved for ION by default; github.com/milkv-duo/duo-buildroot-sdk/blob/develop/build/boards/cv180x/cv1800b_milkv_duo_sd/memmap.py#L43 I think they reserve that much for the exact image buffer amount? Not entirely sure. And yeah 32MB can hurt, but honestly that's enough to run quite a bit - we just seem jaded from these modern behemoth systems. I've not really hit the upper limit, but it wouldn't be hard to solder some NAND flash onto those SPI pads, or enable swap space on the SD card (RIP erase count). The kernel is a tad aged, but 5.10 is LTS and will be supported and security patched until 2026 at a minimum (ref en.wikipedia.org/wiki/Linux_kernel_version_history#Releases_5.x.y). It also appears that the buildroot for this RISC-V variant is maintained by T-Head perhaps (github.com/T-head-Semi/buildroot) which could be imposing some limitations or delays. Glad you enjoyed :)

You could do a single drive for sure, but I don't see the point of sharing a single drive via LAN when you could setup RAID and really leverage the benefits of a NAS with a bit more CPU power. I'd suggest going with the Milk-V Mars (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HuU0LbnTbFk.html) as then you can use a SATA breakout on that NVMe port, but RPi 4B should work just fine too!

@PlatimaTinkers 9 месяцев назад

Hey mate. I use these for mostly IOT purposes; hooking up to my garden sensors and controlling pump relays, controlling my workshop solar setup, etc. I'd say the key differences against Ox64 are; - Fuller SDK - Faster core(s) - Ethernet PHY built-in - More power options - MIPI CSI connector - RDNIS functioning (Ox64 could do this though) - Surface-mountable

For this it uses BCLK, LRCK, PCM, SDI and SDI pins (github.com/milkv-duo/hardware page 42) Then if you look at duo-schematic-v1.1.pdf section VDD18A_USB_PLLyou can see the IIS2 pins are shared with the ethernet interface and could be used. From what I can infer, the IIS1 pins are tied to GPIOC24, GPIOC23 and GPIOA30 which are otherwise used by the mic positive, onboard LED, and otherwise not connected. I am not sure if that ethernet PHY has any supplementary componentry, but I don't think there is much, so you'd just need to use whatever driver or python code to change the C906 pins to the correct mode.

Now THAT is a very valid point that no one on Reddit bought up haha. Most of their arguments were around if it can run a full OS like Linux, not just an RTOS. That being said there is actually graphics and sound, technically, the ports just aren't attached. Eg: - The dual lane CSI means you can easily hook it up to a HDMI bridge like the Arducam CSI-to-HDMI (which includes 3.5mm TRS for audio), or the B100 if that still exists. - Similarly with the ADC onboard you can hook a speaker up to an analogue output and play an MP3 with python. There are probably even GPIO audio drivers available!

Things like the RPi have a SoC with onboard GPU, and I suspect this isn't the case here. The way I see it, this appears to be more closely related to Raspberry Pi Pico than any of the Pi SBCs, and if the term eSBC applies to this, it should apply to Picos. I don't think it does, but you might disagree. Of course, the question of whether sound and video can be software implemented and output and/or input on GPIO pins leads to a very interesting question: to what extent can a system without physical ports be considered an SBC? The Pi Zero needs a USB OTG adaptor to plug a keyboard in... is it a true SBC? It needs a USB hub to plug in a keyboard and mouse siultaneously, so I'm thinking maybe not. In fact, as I recall it the Raspberry Pi Foundation launched it on the grounds that lots of Pis were being used for embedded systems, and they wanted to feed that market, so they weren't really going for the SBC market anyway.

It's meant for a Pi Pico, but all you really need is ~252MHz+ core, 3 PIO machines on the same PIO instance, 6 DMA channels, and 264KB SRAM/RAM. That being said, I had more of a think about it, and it has serial output. That's still a display, in much the same way computers had many years ago. Even though it was monochrome mostly-text, it was still a computer. Then you can also lastly go to the USB-C port. It's only USB 2.0, but you could in theory get a USB 2.0 DisplayLink adapter if there are supported drivers. I argue my stance on 'eSBC' but you do definitely raise a valid point! eSBC is not yet defined though, it's just something I flung out there, so we could say that it has to have network, video, audio and input in SOME form, with maximum a breakout board (not addon board) given the small form factor and intended modularity. So this has ethernet, serial I/O, microphone pins that can PROBABLY be used in reverse, USB keyboard support, and adding more can be done with a breakout board since there is enough power to do it all in software.

Maybe get in contact with me. I sent you money on your paypal so you know i'm not some idiot. I'd like to bounce an idea off of you and fund a video and project if that is okay.

Easy done mate, just replying to your email now before I head out. Cheers

YT recommended this video, I do work on several IOT projects. Your video however did not help me in any way. My language is not English, and I do understand it very well. But. You talk way too fast. And, this video. What is the point of it? Showing your skills? I did not subscribe of course. I hope YT improves its algorithm. Note: I did have to gave a thumbs down, to 'teach' YT this is not my cup of tea.

Hey thank you for your support and the comment! Playback Speed -> 0.75x helps haha. And no, I have no no skills - this is here to share it with the thousands of people that are interested and enjoy my content, plus give an overview of how easy or hard it is to use one of these. If you look at the hundreds of comments, many found this helpful, which makes me happy. Thanks again, and have an awesome weekend mate.

Risk v sucks if you have to actually get something done. Open source does not equal good. There simply is no real advantage.

You're very entitled to your own opinion. But so am I, and my opinion is that you're wrong 😂

@@_specialneedsAh, wrong again! This is where Milk-V does not work correctly out of the box. The RISC-V MCU did exactly as it was supposed to. And everything costs you money if you have a deadline, you just need to choose the right tool for the job. To help you understand a bit here; if you need a daily-use computer, then a Milk-V Duo probably isn't a good choice, however, if you're developing / prototyping an IP camera with onboard neural processing, this is an extremely good devboard to start with. On the other end of the spectrum, it is also ideal for HPC applications, data centres, AI training, and more, given it's beneficial open-source nature and customisable ISA. It's already eating into a lot of ARM's RISC marketshare and benefitting the worldwide compute space by creating competition, spurring-on innovation, and allowing greater access to embedded and high-performance development platforms. The benefit of zero licensing fees is just gravy at that point! Western Digital use RISC-V, Google use RISC-V, Alibaba use RISC-V, nVidia are implementing RISC-V, Huawei is making use of it in their newer hardware, and on and on. I am extremely certain that the engineers at these companies are a hell of a lot smarter than you or I, my good friend. That all being said, again, this is personal opinion - you are welcome to think whatever you would like.
