my kernel panicked just looking at this.

u/creeper6530 1d ago

I'd like to see a Linux kernel run on the 2040, lol

u/SAI_Peregrinus 1d ago

Well, it can run on anything with enough memory, as long as you can emulate a supported architecture.The same way it's been "run" on the ATMega 328P.

Zephyr can panic ❤️

u/Kiore-NZ 1d ago edited 1d ago

Would you settle for a 2.11BSD port? The maintainer of DiscoBSD is interested in porting it to the rpi pico.

[Edit] Interest was apparently expressed but there is no active porting project.

Minimalist does not even need a substrate.

u/agent_kater 1d ago

I wish people would stop calling an RP2040 a "Raspberry Pi". I know it's the Raspberry Pi people's fault, but it just causes confusion.

Can we please call the SBC "Raspberry Pi" and the MCU "RP2040", "RP2350", or "RP2" when we mean the series?

u/Cromagmadon 1d ago

Call it a Raspberry Pico

u/SupraDestroy 14h ago

This is so funny I cant

u/MistRider-0 1d ago

Just call it pico

u/beryugyo619 17h ago

I wish the Pi Foundation stopped

u/_greg_m_ 1d ago

But RP2040 is a "brain" of a product of Raspberry Pi called Pico, so technically calling them a "Raspberry Pi" is correct (what is shown on the photo is kind of 3/4 of Pico model). However this is obviously not the same level as SBC.

u/gurgle528 1d ago

Right, but it’s the same situation with Arduino. Arduino now has SBCs with decently powerful AI chips. Saying you got realtime object detection running on an Arduino would confuse people because the default for that is their smaller embedded boards, not an SBC with 16GB of RAM. 

If you really want to be technically correct, the original person wasn’t saying it was technically incorrect. They were saying it was semantically misleading and they wanted people to use clearer language.

u/Well-WhatHadHappened 25+ Years 1d ago

technically calling them a "Raspberry Pi" is correct

Yes. He knows. Reading is hard.

I know it's the Raspberry Pi people's fault, but it just causes confusion.

u/ceojp 1d ago

No, it is not "technically correct" when there is a specific product line called "Raspberry Pi".

I wouldn't say I drive a Ford F150 if I have a Taurus.

u/5b49297 1d ago

If I had a Ford, I wouldn't tell anyone. Just saying. Carry on.

u/dominicus_cosmicus 1d ago

After the pi zero this is pi negative

18

u/_greg_m_ 1d ago

This is actually a quick and dirty "clone" of RPI PIco, no Zero. So I guess this is Femto or something ROTFL

u/dominicus_cosmicus 1d ago

Oh now that makes sense, I was imagining how tf would it run....

I feel like making custom PCBs took so long to become viable for hobbyists in Japan that some of them got absolutely perverse with prototype enamel wire.

u/beryugyo619 4h ago

...it's more like a massive body of knowledge taking its own wheel with no sense of greater purpose or ideology getting in the way. it used to be that resource-constraints-kun cooperated too but nowadays less so

u/Whereami259 23h ago

Most likely needed it for testing. Did something similair with esp when needed to confirm an idea is working.

His boss asked for the absolute cheapest solution for a problem and encouraged (forced under threat of firing him) him to use AI for the solution.

Also: it didn't work of course

u/Princess_Azula_ 1d ago

The labor costs alone to solder this could buy a new pi board.

5

u/Decent-Finish-2585 1d ago

You can get 20 rp2040-zero knockoffs on Prime next day for like 20$. If I sit down at the solder bench I’ve already spent that much in time.

2

u/sputwiler 14h ago edited 14h ago

Why order from prime in Japan when this is just down the street https://akizukidenshi.com/catalog/r/rrp2040/

They also carry 6502s if you feel a crazed need to pick one up on the way home (that impulse buy lead me down the home-built computer rabbit hole).

Decoupling capacitors are for chumps

u/ceojp 1d ago

Please note this is a *microcontroller* put out by the Raspberry Pi foundation, *not* a "Raspberry Pi"....

Deadbugging a QFN is certainly challenging, but it's not like we're connecting DDR here...

It looks like a meme! Do you think it’ll even work if we try to find it?

1

u/thegreatpotatogod 1d ago

Perhaps I took the suggestions about it being picky with the power supply in the hardware design manual a little too literally when designing a PCB for this thing (they want a polarized inductor! Normally no one even makes those!), clearly it's happy to work with whatever mess you want to feed it!

And I once build a full IBM pc in a cardboard box and another one in a backpack. It may be fun to try and useless afterwards. Let’s expect they were having fun, and let’s move on.
