OLinuXino, a serious Rasberry Pi competitor?

It's only a couple of years since I did my CCNA at the local college as evening classes. Their solution was quite simple: each time you do an IT refresh keep back twenty or thirty old machines for the tinkering classes. If a clean OS install is needed the student does it themselves at the start of the class restoring from a Norton Ghost image on DVD. Any network infrastructure or servers needed for the class is similarly set up at the start of the class. This was for all the courses, not just Cisco.

That worked quite well for them, where each class was at least a couple of hours but I've imagine set up and tear down would take up too much time for schools where a lesson is only an hour or thereabouts.

Additional information -2012-03-10

We started the iMX233 project, the name is OLINUXINO as it will run Linux natively.

The goal is EUR 30 single board linux computer. This is complete open source, open hardware project which is to be hosted on GitHub .

The specs are:

- iMX233 454Mhz ARM9 processor

- 64MB of RAM

- 2 USB hosts

- 1 100MB Ethernet port

- composite Video 640×480 pixels, color, with PXP graphics accelerator for picture manipulations

- micro SD card for boot and disk storage

- headphones stereo DAC with 99dB SNR

- linear input stereo ADC with 85dB SNR

- UEXT connector

- 31 GPIOs for interfacing including UART,SPI,I2C,PWMs

Although this board will run Linux there is possibility DM-BASIC to be ported on it and pre-estimated this MCU should run about 1 Million Basic instructions per second, with 64MB RAM available for applications.

The very preliminary schematic is uploaded on GitHub, the goal is next week to have complete schematic and routed board and in 2 weeks prototypes for the developers.

Cheers Don...

Well, mine crapped out at a much lower current. It is just that ignoring specs that makes that strawberry pudding a request for disaster.

Right, when I plugged the little Chinese mediaplayer into my PC, battery empty, I heard a ticking noise. It was coming from the player, charging, power disconnect, off, on (tick) charging, power disconnect, off, on (tick).... :-)

Cell phone chargers do not put out 3000 mA. They typically put out

0.5 to 0.7 mA... at least the ones I use do. I guess the "smart" phones that run down a 1500 mAHr battery in a day might charge at a higher rate.

I think 100 mA is a bit light though.

l Chinese mediaplayer I have,

There are LOTS of car adapters that provide a 5 volt USB socket, just add standard cable... Mail order places have them for under $5.

Very unlikely anything needs 5 volts other than the USB connector assuming it is a HOST connector for mice, keyboards, etc. But even then the 5 volt port will not need a tightly regulated 5 volts, it just needs to be within the input spec... which is somewhat tight at

4.75 to 5.5 volts typically. But to be sure you would need to check the data sheets for the parts in question. Since there is no schematic available currently, can't do that.

Considering cell phone batteries typically have a capacity of 1000mAh or more, at that rate it would take more than 8 weeks to fully charge it. I guess you are a very, very patient guy ;-)

Um, not. That is the GUI/DE that eats all that RAM. The actual functionality is maybe 5 to 10 % of that. Basic running interactively, with a file system was done in 16 K on a 6502. You have heard of bloatware.

Yeah, well, I guess I'm a patient guy... of course I meant 500 to 700 mA or 0.5 to 0.7 amp. lol

Hmm, strangely enough there was a link in another thread here where the main guys from Olimex were trashing the R-pi a bit and doubting they could make it for the price.

Do you think they have an ulterior motive and not exactly unbiased position?

Are you using the Hollywood edition of C++ with Gibson extensions enabled? (Usually installed under the name 'Java'.)

Memory usage while compiling KDE4 C++ sources from the command line:

PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 1333 root 25 0 332M 316M CPU/0 0:17 96.03% 57.03% cc1plus 1351 root 85 0 48M 32M pager_/4 0:00 2.47% 1.46% as

316MB in use by the compiler. C++ is Peeeg. And then there's Java, which is Mrs Peeeeg after 8 years of marriage..

And it was said this proposed supercheap 64MB RAM RaspberryPi killer would run Android and its Java systems. Uh, you need at least 768MB of RAM for Android to be usable at all.

I'm sure they wish they could sell 10,000 of anything in the first day its on the market. Wouldn't we all?

Ummm-it's not too hard to sell 10,000 of anything if you spec it right and don't actually deliver the product! ;-)

The toolchain were not on the RPi. It was just the target. Just the same your point has been made, those toolchains take gigs.

None of that is by any means trivial.

You need to put significant effort into getting that information out to the right people, convincing the sales channel that this is the right thing to push as well as the media.

Then get 10000 people to commit to buying before delivery

Anyone who can do that needs to put in a lot of effort.

Not delivering - well that is easy. Keeping momentum and recovering from it could be challenging.

I'm just not so sure why so many people appear to want them to fail.

Look at the price,

it's competing with thinks like Olimexino Arm7 (vs Arm11) , 128K ram (vz 512) . no netowork (vs onboard 10/100 (over usb)), no video.

It's even challenging beaglebone, 2/3 of the features at 1/3 the price.

there's even 8-bit boards out there with higher prices.

So to do any programming of the RPi, you still need a PC with Linux either native or in a virtual machine. Of course the same is true of any other low-cost system.

It does seem disingenuous to promote the idea that you could do significant hardware and C software development with the RPi and just a keyboard, monitor and mouse. You really need a PC and a second keyboard, monitor and mouse unless you plan to switch a lot of cables when you want to test your software.

Compiling KDE is a pretty extreme example. I find it rather disingenuous to dismiss the device as unfit for any purpose just because it isn't everything for everyone, especially when the complaints are about things that weren't design goals in the first place.

That would be faster but you don't need an extra keyboard and monitor. You can work remote from a Linux system. Mount the filesystem of the RP using fuse and have the RP use the Linux system as X server for output.
