Ox64 SBC - Connecting, Flashing and Booting Linux! ($8 from Pine64) 

I’ve been hoping for a video like this! I got one too but haven’t gotten to okay around with it, so I didn’t know what to expect.

Glad I stumbled across your channel! You explain things very well!

The pi pico is in no way almost a full fledged computer, it is just an MCU. This board is different though since it has a RV64 processor, a RV32 processor and another RV32 processor that is apparently used for WiFi. This chip also has a built in NPU. It is very different from the pi pico.

I was on the fence re: the Ox as read flashing Linux was super complicated but your video convinced me to give it a go and I await my order and look forward to following this guide so cheers!

Nice! Thanks for sharing this! I'll probably be picking up a few to play around with. It's cool that they come with ZigBee, they should be great for automation.

Excellent. Liked and subscribed. Looking forward to more of your stuff : )

Nice video. A few of these would be really nice for building up a home automation system.

Once the WiFi is working, this will be really interesting. MicroPython is great on Pico W, but it is not a full OS. Really like the full OS aspect.

On the store's accessories page they have stacking headers which might cover less of the pin labels (haven't got any yet as waiting for software support to mature).

Great video, very well explained!

Nice one! Those could be super handy.

Great stuff! Thanks for sharing.

I'd completely missed this board's existence! Thank you for fixing that.

pretty cool device! Hopefully they flesh out a bit more documentation so there's less hunting to get what needs done. I'm in the US though, and our picos are $4/$6 for regular and wirele4ss respectively, so these are a bit pricier than that. that being said, pine64 is definitely an organization worth investing in as far as open source goes.

Amazing device! I can imagine using this SCB to make a portable SDR that can process much larger bandwidth than those made by ESP32 and STM32H4. (H7 I am not sure but H7 is crazily expensive).

WOW, the ZigBee part is super exciting..we got a new player beside xtensa!

Great overview, may have to pick your brain when I get 1.

Nice video of nice hardware.

とてもわかりやすかった

Cracks tinny in the middle of recording…. Subscribed 👍

The RISCV architecture has always interested me. Good to more and more devices on the market. Will definitely grab a couple. Also, is that a Cooper Pale?

A good choice for robotics and automation.

"This is basically running on a fart" - Possibly the most Aussie thing every said.

Nice! Thanks for this. I have a couple myself and eager to give them a go.

For that money it's incredible ! Also having linux kernel and prompt run on just 9MB !

Just had 4 of these show up, keen to see everything I can do with it, both on the Linux side and running code on bare metal.

this board looks VERY interesting, but I think I'll wait for some proper documentation, and to see how they do expansions, audio in particular, because if that 2 ADC 1 DAC @ 8-192kHz claim is true, then I have some nice use-case scenarios for this little fella... do post more videos, this looks promising...

I didn't even finish the video before I started looking for one.

Just one tweak, when I was flashing the d0/m0 lowload binaries I had both at Block 0 as opposed to 0 and 1

Wow. Impressive. Both the result, and path to it. Alas too difficult for me with all those cables and images. I can use Balena, and that's about it.

Looks like soon (once EthX and camera are driven) this will be the perfect node for a chain of low-power and affordable ethernet security cameras. Can anyone assess whether they would have sufficient compute to do local image processing - like face or human detection?

Lot of these micro computers coming out today. "Microdata" will be the new tech wave. Be cool to see this getting LTE-M data going through it.

Ok, here's a question: with Linux on there, can it act as a USB host? Does it have access to the USB with that kind of control? That's the main issue I have with the PICO, that it does not support USB host mode.

Question: I had a crash with M0S board (Boufallo's BL616 single core RV32). * They require custom GCC10, * Zigbee is walled by NDA, * Flash programming is via a custom, unintuitive software * a vast majority of How-tos are in Chinese. How does Ox64/C906 stack against that?

Very nice

This thing seems quite interesting. I wonder if this thing is powerful enough to build a remote RTL-SDR receiver or at least do some direct sampling stuff with a RTL2832U.

Thank you for this video :). This looks promising :). I prefer a Linux kernel and Linux based with Bash to be true. Maybe you could do a simple programming with some I/O devices as a part 2? :) Sub went your way :). My YT is about the electronics repairs and if I've got any spare time, I try to learn programming simple I/O devices. If I can stick to Linux, that's even better :).

Thanks for the video, really interesting. What is the current draw (I assume at 5V) running full Linux?

Finally! A non-bloated Linux installation for me..

I am really interesed in the ZigBee side of things!

Now what I _really_ want to do is run Rust on this thing bare-metal. 64MB of RAM _all to myself_ and whatever protocols I can bit bang from however-fast-that-thing's-GPIO-is without an OS in my way sounds really fun.

Currently looking for a good board to be brains for autonomous rover using computer vision AI (opencv), Lidar, odometry and ultrasonic sensors. If I need a couple of these boards running ROS that would be fine as the price is awesome.

Amazing tiny device! I can't believe it could be possible to run actual Linux kernel on a board with the Arduino Nano form factor. Is Zigbee embedded version 2 or 3?

my 4 pieces arriving today !

could anyone confirm if the USB MIDI host mode is functional? just pluggin a USB controller/keyboard

there is probably a pine64 wiki for this item but it needs a volunteer to write up some documentation. I sent you a message in the red dit post for how to join the pine live chat on this very item since I can't figure out how to be invisible to the YT delete bot.

"Package cannot be shipped to your country due to logistical reasons." Is there other way to get from other stores or without using some random dropshipping services?

looks great for a ginormous nerdy linux smartwatch

Good video! I love how fast it boots, that's a big deal. Also 90mA power draw while idle isn't all that great compared to a rpi pico

Awesome video! Can it handle Scratch app with some screen attached?

Seems like that fills a gap between a RP2040 and a Pi zero I didn't even realise was there.. might snag me a couple, already got some ideas on what that could do.

There is another board with the same chip, it is the sipeed M1S dock and it has a LCD and camera interface as well as two usb C ports, it also allows you to flash the chip over USB as it has a chip or microcontroller built in to handle that, it may be more useful for some people than this board. Since it uses the same chip it should just be programmed the same.

Likely not, but could belena / docker run on this?

Could you do a find in /sys/class/gpio ?

Please don't use baud for serial communications unless there is a good reason for it. Bits per second is what you should use to avoid confusion. Bits per second is exactly what it says. Baud is symbols per second, where the number of bits per symbol varies based on protocol used. It can be 1, 2, 4 or many times higher. 4096 has been common with cable modems, as an example, for several years. UARTs use 1 bit per symbol, so 200K baud is the same as 200Kbps. Way back in the past, telephone modems were initially described as 110 baud, 300 baud, 1200 baud, and 2400 baud. As technology improved it became apparant that using baud was outdated and confusing. After all is a 2400 baud modem able to run at 2400 bps or 9600 bps. Plus modems started offering hardware compression. This lead to having a modem to modem connection speed much less than the modem to computer (UART) speed. With a 9600 bps modem, you might set the UART to 19200 bps, allowing for a maximum 2 to 1 compression ratio. A 14.4kbps modem could have the UART set at 19.2kbps, 38.4kbps or 57.6kbps. What speed you used would depend on the capabilities of the UART, the modem and CPU speed. As modems became faster the UARTS couldn't keep up. When early UARTS were designed 9600 bps was considered high speed. Most computers built up until the early 1990's used an 8250 UART. The first major upgrade was the 16450 UART, which could operate up to 38.4kbps. Then the 16550 UART was released, which included a 16 byte send and 16 byte receive buffer, unfortunately the buffers didn't work. The 16550a UART was released with working buffers and a maximum speed of 115.2kbps; these were needed for the 56k modems and ISDN modems. The final major UART was the 16650 which doubled the size of the buffers to 32 bytes each. Newer models including the 16750 and 16850 (128 byte buffers) were made but much less common. One of the biggest issues during the 1990-2000's era came about because of the UARTS. The 16550a and 16650 were significantly more expensive than the 16450. This meant most computers (and many modems) used the 16450 UART combined with a 14.4k, 28.8k or 56k modem. Many times the UART speed was set at 57.6kbps (or 115.2kbps). After all faster is better and the modems did hardware compression. This lead to dropped packets and retransmissions. This made real transmission speeds drop by a large amount. The people in this situation didn't know that dropping the UART speed to 38.4kbps (and for some unlucky people that had really slow computers and/or 8250 UARTs 19.2kbps may have been faster). Many people in this situation blamed their telephone company, but not all was the telephone company's fault (I'm not saying that they didn't suck). There was the UART issue, there was the issue of ancient telephone lines and equipment, then there was the issue that many modems lied. So many of the El cheapo 28.8k and 57.6k modems would purposelu connect at speeds faster than the phone line could handle. A 57k modem might say CONNECT 38400, but within seconds drop down to 21k (maybe a bit faster or a bit slower). This made users think the speed was much better than it really was, then combined with retransmissions due to an under powered UART and the real speed could be 10kbps or lower. Trying to get someone to speed $30-50 on a new serial board with 16550a/16650 UARTs and $200+ for a good external modem was usually impossible. After all a $250 upgrade to their new $1200-1500 computer that already has an internal 57.6k modem was a hard sell. Trying to explain that their junky 57.6k internal modem can only work at 19.2k was almost as difficult. Even showing how they were only downloading a file at 1KBps before my changes and 1.5KBps to 2.4KBps with the UART set at 19.2kbps wasn't a long lasting change. It always seemed that the next time I came over they'd have the UART set at 56.6k or 115.2k. They'd always say that that is what the ISP, their neighbor, co-worker, friend, or family told them to do for faster speed. Some would even talk about how the modem compressed data. I so rarely won these battles, even when I owned an ISP. Most people couldn't grasp that most data that they cared about were already compressed (zip, JPEG,mp3) and that the ISP used software compression on compressible data. In fact the software compression was better than hardware compression in many cases. This meant that a text file might have a 4x compression. Being limited to 19.2kbps because of the UART would still allow that text file to download at about 9.6KBps. Using hardware compression (probably 2-3x compression) and 115.2kbps UART speed would Max out at 14.4KBps assuming everything works right. Most people at that time rarely had a stable modem connection at 38.4k. Usually it was between 20-30k or 7.5 to 11.2KBps with 3x hardware compression, but only if you had the expensive 16450a/16550 UART. Sorry about my rambling down history's lane.

Can this run klipper and be used on a 3d printer?

I own something similar. It's the Milk V Duo

Cool. I'm most interested in Ethernet

Can you also review sipeed m1s dock

You could run an Amiga operating system in that system.

The price of shipping is stopping me from getting one. I really with they make Aliexpress shop or something like it.

Can this run klipper firmware?

does it have a phy to connect to ethernet?

I use PUTTY and FLASHED BL808. system runs but the 2000000 on the CP2102 I use just will not work. Nothing but garbage coming out the serial port. It will suck if I have to rebuild the OS just to change the baud rate to something normal. Even 921600 would be good. But 2000000 is just stupid to me.

Run Klipper ?

According to the documentation, after flashing, pins IO5 (RX) and IO8 (TX) are UART3. But GPIO5 and GPIO8 dont't exist and pin is RXD pin 8 is GND. Which pins did you connect?

What's nice is from my understanding, you don't even need to use Linux. You can write your own programs on bare metal.

NodeRED will work?

LOLZ @ RISC-"VEE"

Good platform for running OctoPrint/OctoPi?

It got one rv64i core (D0) , one rv32i core (M0) and a rv32e core (LP).

Guessing that Buffulo maybe an homage to Gnu.

5:38 uff

FTDI232 diddnt work for me thought you mentioned it would, although mine is the 232RL and i think others are ok. others reporting the same even at slow speeds. putty console works fine as per your ping/pong demo so the standard ttl protocol should be fine. only an issue when flashing with the "bouffalo dev cube" software. smells like more very intentional dodgy bouffalo behavior (payback for FTDI bricking knockoff Chinese chips ide imagine). in the end got it working with the modified picoprobe provided in the wiki. edit: i should add, for a sanity check after it was flashed and the bouffalo software wasnt needed any more, the linux terminal works fine with the genuine FTDI232RL at 2Mbps again and the picoprobe can go back in the box. the exact one that was knocked off in chena [intentionally misspelled since previous addition got blocked].

That's cool, but where can I buy that SBC? It is out of stock!

How to serial MIDI port suport? And i2s audio dac for standallone MIDI sampler (fluidsynth)under linux

Okay this is a really cool piece of kit. But the amount of fiddling required to program it seems to be a bit much.

It's not "Risk Vee" it's "Risk Five"

The ram is the problem why RPI pico and most other micro can't have a Linux port, kernel needs I think 8MB(or 16MB) at least to run. RISC-V is not a powerful instruction set, comparable with attiny, RV32I set has about 50 basic instruction if it doesn't have any of the extensions.

I'd rather compare it to the Pi Zero instead of the Pico because the Zero runs Linux which the Pico doesn't.

nice! though I don't think calling it a Pico competitor would be fair, since this is a whole SBC and the Pico is just a microcontroller

I can't help but read this as Hex64...

You should do internet radio with 1.8 inch display

Comes out to $19.99 when you add the crazy shipping fee. This comes from China direct? But I am positive that this is well worth $20, it's just that it would be better to go ahead and charge more for the device and less for the shipping. Perception.

and they have a 30$ shipping quote for Europe.

You really could wait and not drink for this 15 minutes and burp into the microphone.

can you flash with linux?

Didn't work for me.

How can i order it?

On the site. Board $6. Shipping $11.99. Lol.

can you make a linux board run on a fart.... ? sounds like a good project for small pc's like this, , maybe not for farts but, body heat , body movment, other small electricity generating "operations"

How to buy one in china

Anyone else have their comment(s) deleted? I made a comment earlier and I don't see it here anymore.

Just like Raspberry Pi.. Out of Stock

Wifi and can run Linux.. hm. Webserver time!

Pico is pronounced "Peeko"

Just needs an esp32 for wifi 😂

No I2S?

Interesting but out of stock -_-

90mA is not running on a fart. That isn't battery capable.
