002 - MilkV Duo, a $9 Linux board

In this video we talk about the Milk-V Duo a tiny Linux board based on the CV1800B, a dual-core 64-bit RISC-V running at 1GHz and that includes 64MB of DDR2 DRAM and an 8-bit surprise!

Nice intro to the milkv duo board. Awaiting more videos on this!

[@non_maskable_interrupt]

Thanks! They are coming soon!

[@PlatimaTinkers]

Interesting take on it mate, much appreciated - did not know of the 8051 before this!

[@non_maskable_interrupt]

Thanks! Glad you liked it! Yeah the 8051 was totally unexpected!

[@M0UAW_IO83]

Had to go back and read that again, at first I thought you meant you'd never heard of 8051 and I felt incredibly old for a moment until I realised (I hope) you meant that you didn't know there was an 8051 in the Duo...

[@non_maskable_interrupt]

@@M0UAW_IO83 yes that is exactly right. I have used different flavours of 8051, from the small 2051 and 4051 from Atmel to those beasts from Dallas (can't recall the pn now). But I was never expecting to find an 8051 core inside a new application processor in 2023! Lol

[@PlatimaTinkers]

@@M0UAW_IO83Yeah bit of a mixed bag. I knew of the 8051 from way back when, but not of the more modern 80251 and similar as I expect is actually used in this

[@felderup]

in circuit cellar 5 steve ciarcia made a supercomputer with 64 8751's as slave processor nodes. with smt versions it might be pretty tiny, and worth a shot at doing a modern build of. what might be possible with these milkv's?

[@bitflipper]

Great overview on the Milk-V Duo, Fabio. Thanks.

[@non_maskable_interrupt]

Thanks!

[@AnotherByteData]

Very nice Fabio! This board is really interesting! Very low cost!

[@non_maskable_interrupt]

Yes it is! I was totally not expecting all the builtin features!

[@ruhnet]

Great video!

[@Freireg1503]

Nice video! They recently updated the build root sdk to enable the second core with FreeRTOS. Once you get the hang of it is very interesting to use

[@non_maskable_interrupt]

Good to know!

[@AymanFakri-ou8ro]

great overview, thanks!

[@non_maskable_interrupt]

Thanks for watching! More to come!

[@fernandolichtschein4222]

You are right, "folder" is a Windows term.

[@hamburgengineer]

Do you think Linux can run a full OpenCV version, like a Raspberry Pi can?

[@FATTIdotCOM]

I read the datasheet 3 times and I couldn't find any power consumption ratings. Yet, I couldn't find any CE mark.

[@non_maskable_interrupt]

Yep, I just noticed my link to the datasheet was broken and updated it. The new datasheet still does not show any details on power consumption, just the approximate 500mW for the hypothetical usecase.

[@Otakutaru]

I wanted the white PCB version so much... Came out blue for me

[@non_maskable_interrupt]

I guess I was lucky!

RISC V non RVV(1.0) Vector Computer

[@protektwar]

ADC works at 1.8V only as specified in Datasheet... In order to have a working Ubuntu, swap partition should be created prior running the system, otherwise with 64MB of RAM apt will not work at all. With swap partition will work very vert slow although the apt porcess with use only 4-6% of CPU.

[@non_maskable_interrupt]

Interesting. Why are you planning to ruin Ubuntu on this machine? Any reason in particular?

[@protektwar]

​@@non_maskable_interrupt with what else if not with Ubuntu?

[@non_maskable_interrupt]

What I mean is that Ubuntu is a distro. But Buildroot can build anything so you add packages (apt?) to mimic a Debian system like Ubuntu or you can do something else. AFAIK the default package management on Buildroot is opkg which is much more lightweight than apt. But if you want desktop-like experience and turnkey then Ubuntu core might probably make your life easier. Thanks for your comments!

[@llothar68]

64MB. What a dream i had about this when i developed my master thesis project. Now it won't even run an installer 🤣

[@jacobdavidcunningham1440]

11:09 lol I come back to this video like wth

[@non_maskable_interrupt]

Lol yeah Donald Duck or more like Chipmunk!

[@pu5epx]

Would be perfect if came with the Ethernet and/or Wi-Fi.

[@non_maskable_interrupt]

It has RNDIS over USB and there is an I/O board that includes an Ethernet connector and a USB hub with four ports! Of course it adds up to the cost...

[@putyavka]

Actually it has Ethernet pinout on the side where sd card located. But integrated wifi would be much better

[@udirt]

Make the Browser Window a bit smaller, you're smaller than a tiny sbc :-) (says person who never made a video with a cam video ups)

[@non_maskable_interrupt]

Lol! Thanks for the feedback, yeah I am still playing with all these things, but it is hard to find the right balance!

[@jyvben1520]

why did donald duck appear ?

[@non_maskable_interrupt]

Lol Donald Duck is an icon! But yeah it was an experiment, I did not want the video to be too long and boring so I thought fast-forward would be a good idea, but now I can see it did not help!

[@robby.roboter]

KZbin can change speed of video :)

[@eglintonflats]

It appears you possess a discerning acumen in the art of textual interpretation, albeit with a rather limited proficiency.

[@non_maskable_interrupt]

Sorry to disappoint!
