she was pissed when someone blew up her guidestones.

Even before the drives she would be mad at me, pointing her finger and yelling 'how dare you'. this machine is a beast.

 

Might be fun actually.

OEM PSU arrived yesterday.

Guess what? Still wont boot, same thing powers up, loses power, reboots. repeat..  .  **(&T#^%W#)_

I probably missed some other posts on this subject, but this sounds like a bad motherboard.

It may be, or it may still be f-ed up Uboot. But, i'm not the only one still in this boat. Many have managed to find PSUs that work ( its random.. but most dont ) or wired it up directly. And it does sill act 100% like a PSU coordination issue, not a dead board. I could wire up a serial terminal and watch it try, but i dont care that much.

The entire roll out of this has been a disaster.  

If they dont fix Uboot soon, i may just hardwire it, or set it on fire. This was just to be a toy, as i'm not really doing any projects now, so not going to spend too much of my time forcing it to work. But i am curious how well it does, as its the next generation up from my other arm chips which i'm found of ( they are RK3399, this is RK3588 ), and should be around the same functional level as a mid-range i5 + its got AI stuff too. So in theory, a desktop that fits right in the middle of most things out today in the x86 world.

 

in hindsight, i should have just cancelled it, but i sort of forgot it was still out there until it was coming. I pre-ordered in mid-January.. Stupid supply chain problems delayed these chips a good year.

 

I still have that RiscV sifive version 2 coming next month. No real need for it too, but the novelty of having it won over common sense. Sort of neat having fully open commercially supported hardware running fully open software. Never dreamed that was possible 30 years ago. ( this one adds 2 more cores + GPU + M.2 slot and an extra 8gb ram. A bit more usable than the v1 board i have now ). In time RIscV will eat ARM.

I went to only solid state drives here a while ago.  I had forgot
**HOW FREAKING SLOW** spinny disks are.   geesh. i'm about to rip

Dude. You're using 7200 RPM disks. Those are the slow ones we use in our data centers as "cheap and deep" near line storage.

I have one in my main machine at home for backups. I use `hdparm` to make it spin down when it's not being accessed.

I still remember when they were fast. Yes i know they make 10k and more, but its what i was given for free.

And yes, they are now on a shelf, can be used for off-line backups if i need them.

Right, but 7200RPM used to be the desktop standard (before the desktop standard got even slower, i.e "we won't tell you what the RPM is) and before desktops moved to SSD.

10K/15K RPM is a lot less dense, hotter, more expensive, and consumes more power, and never really caught on for personal use outside of crazy gamers.

Thanks for clearing that up. I was reading this thread with my 7200s and feeling inadiquate and embarassed that I thought they were "the fast ones" when I bought them. I actually don't think I've ever seen a 10K RPM disk before.

Somewhere i worked at we had 10k drives in servers, and they were stupid expensive from what i remember.   Been a long time since i had to deal with hardware at the office.

i know i have not used spiny disks for a long item other than backup where i dont really keep track of time, start and walk away.... So i clearly have forgot, but man, its soooo different from even a cheap Chinese SSD..  ill never go back again.

Right. About a decade ago we were fitting our data centers with 15 KRPM disks as primary storage, 7200 RPM disks as "cheap and deep" storage, and much smaller SSD as "flash cache". High end storage systems were the first to implement auto-tiering, so the most frequently accessed data would end up on the fastest disks.

Nowadays, spinning disks are mostly extinct in our data centers. We're pretty much only using them for backups and archival.

Well i was doing some rearranging of stuff today since i made a lot of room tossing the last of my dead-tree books last couple of weeks ( and some other things too ). Pulled out one of my FPGA dev boards. Set it on my desk.   looked at it for a while then put it back.   

 

Almost...  Perhaps next time.

LOL I mentioned in my recent Rants rant that I lack low-level embedded dev confidence when job shopping. This is roughly a yearly tradition for me. I have a bunch of eval boards and microcontrollers and other little goodies, and every so often I get the urge to pull out my breadboard and tinker with it. Sometimes I even make it so far as to actually turn something on and hook up to the UART. Then it sits there for a month collecting dust before I finally say "this is stupid, I'm not going to do anything with this" and put it back in the closet again until next time.

I was an EE in a previous life. Earlier this year, i gave away nearly all my 'component' gear.  Parts, breadboards, chips, scope. generators, bla bla etc.  Several SBCs too

Only kept a couple of things, in case i ever got the urge to do 'something' but i know i was kidding myself if i ever thought id get out some resistors, caps, wires and stuff again and do it by hand... Worst case now id use an FPGA as the 'hard way' instead of discrete components, or one of my 'all in one' sbcs with grove style sensors and some python code.   

The  'fun' went away decades ago in all my hobbies. Part of it, i made my hobby my job back in the 80s. Big mistake. The other part, is just me i do realize, "fun" just does not exist.

 

I think i mentioned once that just after i gave away the last batch, i needed a resistor to test a sensor in the jeep. Just one 1k ...but  i didnt have *anything* left..  had to go ask the dude if i could have one back..

oooooo out of the blue the VisionFive/2 arrived today.  Never got a tracking number or even a shipping notice.

 

Now the "fun" begins of trying to make it boot. THIS im ok with needing some extra effort as it is new technology, unlike the ARM hoard i'm still pissed off about.

This summer perhaps, a RISC-V phone and tablet.   The new sispeed SOM that comes out in a month or 2, with a typical dev-carrier board ( which is pretty impressive according to the proposed specs ), but i guess they are going to start building things around the module on their own, and not just rely on 3rd parties.   

The planned 7 socket mother board sounds cool too.. mmm

Too bad it wont fit in my pine book pro..  different pin-out.

So ... what can you *do* with a RISC-V SBC at this point? Is it just the thrill of playing around with a new and hopeful architecture? I like the idea of getting more of the world moved over to an open source ISA, but once it's up and running it's basically just another Linux machine, right?

It is pretty cool, though, that the presence of an entire open source software ecosystem makes this kind of thing even possible.

For current boards i have seen/own: Embedded IoT device, a headless server, or a low-end desktop. Depending on which one you buy. in 2023 it will be competitive desktops you see and AI enabled devices.

i cant comment yet about my SF-v2 board with GPU as far as using it as a desktop, but i suspect more medium end level. intel i3 comparison is my guess. Just not that far yet. My v1 board worked, ran a desktop. Just was slow. But it wasn't meant to be a desktop really, just an early model to experiment with. No GPU or storage beyond SD. But it worked. it was neat.

Lots of IoT devices out there now ready for production use, and in-use.  Desktops/portables are next ( i bet mostly Linux and later android as they get into the tv box market ). 

IoT devices are both Linux based and bare metal, im sure other options will come. One of mine runs Debian, another is bare metal. t has a LCD display, camera, battery, grove ports, and a nice pretty case . I hear the small boards are already clawing at the IoT end of arm. and ESP32s have already switched over. The momentum is there.

One thing missing in the Linux desktop build was a decent browser. But it will come, we are still early in this game.

But to answer the question, i donno, assuming the V2 board is like an I3, what can you do? Well, what can you do with any computer ...

Oh, and at a micro level, RISC-v is in all NVIDIA products, apple silicon, western digital and a bunch of others.  its 'glue' at this point, but its out there a lot more than anyone really realizes.  Sort of how minix slowly evolved to be *everywhere* but no one noticed.

Right, so it's at a point now where it is being used simply to avoid the cost of a license, which is where the open source software world was 25 years ago.
It has not yet become "the" ecosystem that is everyone's first choice becuase it is encumbrance free and permanently vendor neutral.

Hopefully we'll get there and it doesn't take quite that long. Software that is hard-built to a particular architecture and platform is not as mainstream as it was a generation ago. Open source infrastructure and web based software have made it easier than ever to jump around. Perhaps my current motherboard will be my last AMD64.
