Tinker V: Single-board RISC-V computer
- peoplearepeople 4y agoThe first RISC-V single-board computer.... from ASUS that is
- jerrysievert 4y ago(from Asus). there are other SBC's available, like the mango pi mq pro, which is in the form factor of a raspberry pi zero.
- whitehexagon 4y agoDid I miss the pricing? I quite fancy the "StarFive's VisionFive 2" that was mentioned here a while back (assuming software improves a bit), but once again not clear what this new board offers in terms of RISC-V extensions/level of support. btw I noticed today that Pine64 are also planning a cheap RISC-V board maybe next month.
- FullyFunctional 4y agoIt adds a much slower CPU /s The VisionFive 2 is currently the best RISC-V SBC option, at least until TH1520 becomes available (next month?), depending on the price. I can vouch for the VF2 hardware - works well. Alas PCIe is oddly slow, but I'm hopeful that firmware will improve that. EDIT: The Pine Star64 is (should be) the exact same SOC, so it should be basically the same as VF2 (small differences like PCIe edge connector instead of an M.2 slot, etc).
- brucehoult 4y agoPeople are getting around 250 MB/s from an SSD on the PCIe (M.2) on VisionFive 2. Ok, so you'd ideally like 400 MB/s from 1 lane, but it's still 10x better than SD card. It's probably being limited because the RAM to RAM copy speed isn't much more than that! I get 475 MB/s memcpy() speed for 64 MB copies on my VisionFive 2. The much slower CPU on the AllWinner D1 manages 1100 MB/s n the same code. Somehow the SiFive-based SoCs have never been good on RAM speed -- the HiFive Unleashed and Unmatched were even worse than this. Hopefully the Horse Creek SoC has some good Intel DDR IP in it.
- FullyFunctional 4y agoI'm getting ~ 180 MB/s on a Samsung SM8?? which hits around 3 GB/s on a desktop. I'm using a 5.1V 3.5A supply so that ought not be the issue (but I'll try another PSU now). Horse Creek would be nice - should it ever become available for purchase. EDIT: Well, I'm shocked. With a far more beefy supply (12.3V/0.7A) I now hit 295+ MB/s, not great but so much better than before. Thanks for the hint.

- brucehoult 4y agoInteresting data, thanks!
- FullyFunctional 4y agoNobody called me on my nonsense so I will: The 5.1V 3.5A = 17.8W was the PSU _rating_ whereas the 12.1V 0.7A = 8.5 W was actually _meassured_. I’m not a EE and I don’t understand the power section of that board, but something to look out for.
- brucehoult 4y agoYes, it didn't seem to make sense butI figured it was a typo and the more important thing was the increased SSD speed. What is the rating of your bigger supply? And presumably what you were measuring is the average Amps/Watts, not the peak.

- CharlesW 4y ago> Did I miss the pricing? If you follow the "Where to Buy" links for the United States, it's available from Amazon for $280.
- microtherion 4y agoNo, that link goes to the Tinker Edge, a board with a different CPU and a TPU. As far as I can tell, Amazon does not carry the Tinker V at all.
- metaphor 4y agoNope...the Amazon page that ASUS redirects to[1] is a different SBC[2]. [1] https://www.amazon.com/ASUS-Tinker-1-5GHz-Graphics-Motherboard/dp/B083FM7Y4M https://www.amazon.com/ASUS-Tinker-1-5GHz-Graphics-Motherboa... [2] https://tinker-board.asus.com/product/tinker-edge-t.html https://tinker-board.asus.com/product/tinker-edge-t.html
- CharlesW 4y agoYou're right, thanks! Here's the "Where to Buy" page that sent me there: https://tinker-board.asus.com/where-to-buy.html https://tinker-board.asus.com/where-to-buy.html
- whitehexagon 4y agoThanks, I only scanned Europe. But anyway that is quite a premium over the SV2 at around $70? And I got the impression Star64 will also be in that lower price bracket, but lets wait and see.
- rektide 4y agoPretty cool seeing a RISC-V chip from a longstanding well known name in chipmaking, Renesas.
- chunk_waffle 4y agoWish the SuperH stuff would have panned out, the open source stuff seems to be dead on the vine :(
- rektide 4y agoAgreed. The j3 & especially j4 cores would have been very interesting baselines to compare against. https://j-core.org/ https://j-core.org/
- Reitet00 4y agoLooks nice! Too bad it's not PoE powered. That'd be great for simplifying IoT provisioning.
- johnwalkr 4y agoWould be nice but it's easy to add with an external adapter.
- squarefoot 4y agoGiven the use and current draw, it would probably require a fully 802.3 compliant active PoE adapter, which would add some ~20 bucks to the cost.
- johnwalkr 4y agoAnd a lot of power (probably same or more than the device itself). Some space on the board too. While I think it would be nice to include on the board, it is for sure the better option to not include it and let people use an adapter for their use case.
- unusual-name 4y agoApparently the CPU in this SBC violates the RISC-V ISA pretty badly. [1] [1] https://lore.kernel.org/all/CA++6G0Do001Bo+kxhUNz5T937TYU-K5Y43MH+X=Q2TgFCaxcfQ@mail.gmail.com/ https://lore.kernel.org/all/CA++6G0Do001Bo+kxhUNz5T937TYU-K5...
- pclmulqdq 4y agoKeep in mind the spec being violated is the privileged spec, not the core instruction set (which is what people think of when they think of an ISA violation). Personally, I think the privileged spec is a little too overzealous about the implementation-specific details that it specifies, and a little more should have been left to chip vendors.
- mikevin 4y agoWhy does the ISA spec define the starting adress of the text segment anyway? Struggling to find a good reason.
- pm215 4y agoIt doesn't. Effectively the architecture spec defines behaviour so that it shouldn't matter what you choose for the text segment starting address, but this implementation's non-standard behaviour means it does matter, because there's a weirdly behaving address range you have to avoid.
- snvzz 4y agoIt doesn't. This implementation has a very incompatible (and problematic) deviation from the privileged ISA spec. It seems to act as if there was a hardcoded, stuck, TLB entry that cannot be removed, so the whole system has to work around it. And to add insult to injury, it affects a virtual memory address range that happens to be used in most Linux programs. IMHO ASUS is doing a disservice to RISC-V by releasing a board with such a chip. They should have used something else or skipped this generation.
- Pet_Ant 4y ago
- fortysixdegrees 4y agoIn my work I have had to evaluate a whole bunch of SBCs, and the Asus Tinkerboard is a cut above all the others. I expect the quality of this board to be similar
- chunk_waffle 4y ago> The first RISC-V single-board computer > from ASUS The "from ASUS" part is pretty important to that headline IMHO...
- msla 4y agoHey, if Apple can be recognized as the inventor of the GUI...
- rocket_surgeron 4y agoAre they? As far as I'm aware, there are only categories of people when it comes to "the invention of the GUI": 1. People who know it was a long and involved development process involving many people starting in the 1960s. 2. People who don't care. edit: Lol y'all some bitches.
- garbagecoder 4y agoApple didn't "invent" the GUI and Columbus didn't discover America, but they popularized it, at least among a certain set. No one was popularized RISC-V yet. Maybe Asus will be the one!
- aacid 4y ago> Micro-USB Honestly??
- wyldfire 4y agoProbably saved a good $0.45 using a cheaper header. :(
- thrown123098 4y agoOr it was the only one they clild get in volume. The last 3 years have been merry he'll on supply chains.
- johnwalkr 4y agoConnectors, especially ones made by multiple manufacturers in the same footprint (including usb-c)really weren't hit hard by this.
- bayindirh 4y agoThis is an enterprise/industrial IoT board with CANBus and RS232. These people carry RS232 over Ethernet and call it a revolution. I’m sure that finding MiniUSB is much more easier on that setting and ecosystem.
- wolrah 4y ago> Or it was the only one they clild get in volume. The last 3 years have been merry he'll on supply chains. This is Asus. They make a phone that has two USB-C ports, plus a variety of mobile accessories that all have one. They also make laptops, desktops, and motherboards that generally have 2-4 of them. I'd be shocked if the sales of the entire Tinkerboard line added up to even the mobile products alone, much less the PC lines.
- wolrah 4y agoAmen to this. I wish the USB-IF would officially deprecate the entire mini and micro line, stating that they are not allowed to be used and will not be certified compliant in new hardware designs unless the new design is intended to be a physically identical drop-in replacement for an older design that used those ports. There is no good excuse for these ports' continued use in new designs, just penny pinching nonsense. Host-side ports can be full size A or C, device side ports can be full size B or C, anything else is just being cheap.
- uticus 4y agoI'm confused. When I click on "Where to Buy" it sends me to an Amazon page with these specs: > CPU and GPU: Quad-core ARM Cortex-A53 and integrated GC7000 Lite Graphics > CPU Socket Quad-core ARM Cortex-A53 > Chipset Type Quad-core ARM ...am I right to expect something not ARM? [edit] nm, apparently the SBC series also offers ARM
- st3fan 4y agoUnobtainium? Doesn't actually seem to be for sale anywhere?
