Re: Lemon Pi, $35 ARM Quad-core A9 open source board

Mon Aug 03, 2015 5:11 am

In case no one noticed, they made their $10,000 goal with about $400 to spare thanks to some Chinese hackspaces making some last-minute bulk orders. It appears they're still taking orders as perk links still seem to be live. They posted about a month ago that they're late shipping early-bird boards due to some hardware improvements and fixes.

It's nice to have a command economy where some People's Liberation Army general and/or party official can just say "Make it so, Numbah One" to prevent someone from losing face. Maybe it really was a bulk order from some hackspaces acting of their own volition, and the number ordered is a drop in the bucket for the 300 million Chinese in their version of a middle class that's starting to be able to know what to do with, let alone afford such luxuries as high(er)-performance SBCs.

Executing lshw on a pre-production Lemon Pi shows the ARM CPU clock speed to be 1.04 GHz and that the cores are A-7, not A-9 as stated in the IGG campaign summary. Not sure whether the clock speed is calculated by lshw or just read out of ROM and whether the core type labels may just be strings from an older design that hadn't been updated yet for the initial production spin. If it really is A9 it should be 20 ~ 30% faster than the RPi 2 cores at the same clock speed, and being bit higher in clock speed at 1.04 GHz may give it a bit more overall speed.

The PowerVR GPU clock speed is reported to be 550 MHz, which is more than twice that of the 250 MHz of the Pi VideoCore IV GPU. This may be a generation newer than the VC IV, but I need to run some real-world OpenGL ES demos to get a feel for what it can really do. I wouldn't expect the PowerVR to be as open-source as the VC IV given its relative shiny newness.

The most exciting thing appears to be the USB 3.0 port, which seems to be for real and that may be one true advantage over the RPi 2, along with the on-board 4 GBs of eMMC flash memory and support for 1.8 volt Ultra High Speed mode micro-SD cards. So, true Class 10 performance should be possible to upwards of 30 MBps reads and somewhat slower writes (but should still be well above 20 MBps, depending a great deal on card geometry).

Analysis, as they say, continues.
The best things in life aren't things ... but, a Pi comes pretty darned close! :D

This seems to be the same board as (or very very similar to) Actions Technology's bubblegum-s500 devel. board

Sure looks like it. It also adds one specification that I never saw mentioned on the Lemon Pi...the power draw. I'm a bit dubious about that, though, since the board has 2 USB 2.0 and one USB 3.0. It ought to be able to provide upwards of 1A for those ports, and that isn't going to happen with a 700mA input.

I notice that the linked page omits the same things the Lemon Pi material does...CPU clock speed. An A9 core *ought* to run at around 1.5GHz (per Wikipedia), but these guys haven't given a clock spec.

Should they have created a foundation first? Their phony fiat currency is just as fake as your fiat currency. So face the economic reality, the banksters pre-ordained Facebook and Google to be successful. Their competitors never stood a chance.

The USB 3.0 port is the only reason I gave it a second look... Banana Pi M3 is an eight core and the new Orange Pi Plus uses a fancy H3 chip.

Which currencies do you consider to be "fake"? For that matter...which ones do you cosider to be "real"?
The USB 3.0 port is the only reason I gave it a second look... Banana Pi M3 is an eight core and the new Orange Pi Plus uses a fancy H3 chip.
Banana Pi M3 is (per Alibaba) $58 to $65. Oddly enough, the developers say that the SoC can be clocked as high as 2GHz, but the M3 is (apparently) only set to run at 1GHz, which means that the only thing is has over the Pi2B in that regard is the extra cores (and 8 cores aren't going to actually run twice as fast as 4 cores) and double the memory. At raw clock speed, it is only 11% faster than a Pi2B, yet costs about 60% more. (I'll grant that I consider the SATA port a real plus, though.)

Orange Pi Plus...that "fancy" H3 chip is 4-core Cortex-A7, just like the Pi2B. Advantages are that it has a SATA port and--apparently--a 1.6GHz clock speed. That would make it faster than the Bpi M3.

There is yet anotherhttp://linux-sunxi.org/H3 H3 board, Orange Pi-PC with a self adjusting CPU speed from 480MZ to 1.54GHz.

Please check this link for further details http://news.softpedia.com/news/orange-p ... 2924.shtml

Though it will run Raspbian, " Wolfram Language and Mathematica Bundle" will not work. That alone makes this $15 board a lot more expensive than Raspberry Pi-2 B to many many people :?

OK - I actually didn't know if anyone used it. I always assumed it was one of those things that they acquired (for free) and said "Hey, let's put this in - it's free after all..."
And some folks need to stop being fanboys and see the forest behind the trees.

the wolfram Language is a very math topical "programming" language, I advise you to learn more about mathematica, and the wolfram language.

Same SOC as the Lemon Pi. The name suffers from the usual defects, but at least it isn't as bad as Lemon Pi. The RAM is nice touch, though.

And, while I'm on the subject... The lemon Pis from the IndieGoGo campaign were supposed to ship in August. They didn't. Nor did they ship in September.

Nice...but I specifically noted that eh *Lemon* Pi hasn't shipped, and they were supposed to out in August. They're over a month late. (Not that I'm terribly surprised...)

So apparently Roseapple Pi and lemon Pi are exact same boards... just different sellers.
the only difference being that lemon pi hasn't started shipping yet but i received my roseapple pi.

here's a little intro if ur interested: https://youtu.be/dfnCwrq1xmo

Yes, I know this is necro'ing the thread...but it's appropriate.

I received my "Lemon PI", actually a Roseapple PI, that was supposed to be shipped last August....yesterday, April 1st.

I have it up and running. Clock speed is 1.1GHz. It has 2GB of RAM. I can't find any sign of on board eMMC. There is a downloadable image file for Debian. It works, but the last update was Nov. 30, 2015 and even after an apt-get update/upgrade cycle, the installed xscreensaver complains about being horribly out of date. I may just uninstall it. I'm less than impressed with their Debian build. Ssh-server wasn't even installed, for instance. So far, I can't get the screen resolution to allow for anything other than 1280x800 (my monitor is 1920x1080). On the other hand, the Debian build is Jessie, even though the kernel is 3.10.

Had this board arrived last August, it would have been a nice bump in performance over the then-top-of-the-line Pi2B. With the existence of the Pi3B, not so much. It's sort of a Pi2.5B. One article I came across from last October (which claimed that the Lemon Pi boards would be shipping "soon") said that the Lemon Pi and Roseapple Pi were both using an Actions (the SoC supplier) reference design.

Advantages over the Pi: 2GB RAM, 1 USB 3.0 port, A9 (vs. A7 on Pi2) cores. Disadvantages: No sign of FCC or CE approvals. Only 2 USB 2,0 ports. As is typical of most non-RPF SBCs, poor software support (took some digging to find out what the default ID and password is). Slightly larger PCB than any Pi B-series board. Neutral: It came with a heat sink installed on the SoC.

Once I get a few bits and pieces (probably within the next week or so), I plan to run mass storage speed tests, specifically on the PiDrive (native USB3) and an SSD (SATA-III) using the USB 3.0 port.

I've had this one for months now, heats like hell and the screen resolution issue is due to the fact that the resolution is coded into the .dtb file and cannot be changed at runtime.

Hmmm..... Good thing I'm not seriously trying to do anything critical with it. Hard coding screen resolution in this day and age (unless said code is fully documented and under user control) should result in the person making that design choice being taken out back and shot.
