Lemon Pi on Indiegogo campaign,$35 ARM Quad-core A9 and Imagination PowerVR SGX544 open source board

[Embed Studio]

The Lemon Pi is a very low-cost open source single-board computer (SBC) equipped with a powerful ARM quad-core Cortex A9 microprocessor integrated with an Imagination PowerVR SGX544 GPU.There are a lot of the same characteristics between Lemon Pi and Raspberry Pi 2，such as the price,the size and the compatible 40 pin interface and so on.But the Lemon Pi has more powerful computing and Imagination GPU hardware acceleration capacity,more IO interface expansion etc.More importantly, Lemon Pi supports many specifictions that Raspberry Pi 2 does not support, such as USB3.0 host, OpenCL that Imagination PowerVR SGX544 supports, android 5.0. S500, which is one of Actions Semi open cource chipset series called ActDuino, is adopted on the Lemon Pi.

SDK is being prepared. you know, Lemon Pi is on campaign process. Everything including code/document/datasheet/hardware material etc. will be availabel as soon as possible.

Hi,

Stupid question: isn't this kinda off-topic for this list as the SoC on the LemonPi isn't an Allwinner part?

Thanks,

Julian Calaby

Are there lists for these other Chinese vendors?  I haven't found one for Rockchip or AMLogic.

I'm not aware of any either, but I haven't had reason to find them
yet. - I don't have many ARM devices and haven't had a reason to do
any development for any which aren't Allwinner.

I don't think that neither You (EmbedStudio) or Actions Semi understand
s what "Open Source" means.

There's no mention of Actions Techology SoCs in the latest mainline
kernel tree and neither in relevant mailing lists. Besides I can't even
find a proper datasheet or programmers manual for S500 SoC. And good
luck with PowerVR.

Therefore please stop spamming because this list is for discussing
Allwinner SoC hardware and relevant Open Source projects.

As stated on http://linux-rockchip.info/mw/ it is on googlegroups as
well: https://groups.google.com/forum/#!forum/linux-rockchip

For amlogic, things are not as far advanced:
http://linux-meson.com/doku.php#community

ActSemi seems to have no community at all.

When it is stated that linux-sunxi is special, then they are not lying.

This is very off-topic and should be considered spam indeed.

So this is what the crowd-funding and/or "raspberry pi beater"
golddiggers have come to these days...

Hi Luc,

Apparently so.

I'm waiting for them to run out of fruit options.

Thanks,

just to keep this thread REALLY out of topic, the "fruit race" remembers me my early days (80ies..) of computing when my father bought me and my brother a not so cheap Apple //e (beware the precise syntax.. not an older Apple ][  :-) but there were already at the time, the "china clones" (at the time the 6502 based Apple was more or less an open design..) with resembling names like PearPc or Lemon and Orange.. (as far as i remember..)

it's really true that history repeats itself periodically! :-) ..sorry for the unuseful post, no tree has been harmed anyway for it!

Not only China, but Europe and South America too.

Somehow, this discussion about history repeating is more interesting and
ontopic than the spammail it is based on :)

There are quite of a few things to do and probably should have been done before the campaign on Indiegogo.

1. The campaign on Indiegogo is a "Flexible campaign", which means that even if you do not manage to reach the funding target, you get to keep the money. 

The standard Indiegogo campaign type ("Fixed") is to return the money if you do not manage to reach the funding target.

If you go for the Flexible type, you need to build confidence that the device is working and what you are promising can be delivered. 

For example, you mention on the Indiegogo page that you ported the device to Ubuntu. Here you can show the dmesg output (put it on pastebin.com), 

run benchmarks or provide other relevant information.

You can also send a sample to websites like cnx-software.com so that they can review it for you.

2. The position that Actions Semi is now, was probably what was with Allwinner at around 2012 (that is, in early stages for a developer board)

There was a campaign on Indiegogo at https://www.indiegogo.com/projects/cubieboard-open-arm-box#/story

But before that campaign, there was (independent) developer effort and confidence. 

You may want to contact Tom Cubie (from Cubieboard campaign) and ask for advice.

3. Actions Semi is a new fabless company, so in order to gain the interest of developers/users, 

you need to do some things much better than what is available with existing developer boards. 

Finally, this Google group is about Allwinner SoCs and it does not look nice to talk about different SoCs here.

There are generic technical Linux ARM mailing lists such as those at http://www.arm.linux.org.uk/mailinglists/lists.php

Hope this helps,

Simos

Well, things are going on actually. Really slowly since I'm basically
the only one working on it, but they are going on.
