That sounds amazing. What are we looking at in terms of expected price?

Yep. That monster is showing some life! It is actually looking good. But there is that other issue we always seem to have to deal with.

Processor availability of a new part. We plan to build  a limited number of these initially just to make sure we get it all pounded out before we build a bunch of them.

Oh and we also have a plan for a lower cost version based on a single core version.

He's probably irritated about the 'sgx' graphics. He's more then free
to contact TI, place a $bil order and request TI use an "open source"
gpu, probably take around a year for development.

Or he could just start reverse engineering sgx or pay someone. But in
my 6 years working bb.org no user has done that and gotten anywhere
yet..

Beagleboard-x15, the nexgen pseudo-opensource hardware based on
TI AM5728 SoC dual core 1.5GHZ A15,2GB DDR3L (dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x1080@60),separate LCD
port, video In port, 4GB eMMC, microSD, analog audio i/o, dual-Gb
ethernet.

Will it fall under $100 or will it be $100-200? Make your bets.

more like "mob" open source.. you can start making a board

Because they don't want you to compete with the foundation..

You got me wondering because Richard basically copied his info
from Nishanth Menon himself:

https://patchwork.kernel.org/patch/5245961/

"BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHZ A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x108@60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet."

So where's the truth? :-)

AM5728 looks exciting, in particular the 2xC66!

I must admit to a little curiosity about the design process.
Is there a particular reason to avoid DIMM socket RAM?

I find the idea of recycling old PC RAM, or buying new from a PC shop, rather appealing.
I get a cheap(er) board, can upgrade, and can even venture into overclocking...

Looking at BeagleBoard-X15 wiki, I like that the connectors are only on two sides, so now it is possible to use enclosures like this:


Pricing is pretty reasonable:

I see almost nil GPIO pin headers on this board. How many GPIO pins would be there on this one, and would it include all the PRU pins?

Also, just to confirm if there's an eSATA port onboard.

There is only four connectors with 66 pins each, so I could only get 157 GPIO pins on it. And yes it is eSATA.

BTW, the connectosr are on the back of the board. You can see their mounting holes from the top of the board, three on each end. The connectors are SMT.

I'm just hoping that the pricing is right - this is a killer board at around 150$.
Not sure if this can replace a desktop but it sounds like a good NAS/Media server/HTPC builds though that might not be an intended application of this beast :)

Is it the PCIe part which isn't open source on the board?

Ok "definitely" must mean $200-400. Is this not good guessing?
This starts to be a in different realm and the competition is more
fierce. But you know more about that than I ever will and it's
likely that I just don't understand the landscape. Dual Gb ethernet
will attract a lot of attention for server/firewall/IDS/IPS.

Both PCIe ports are connected to the expansion headers.

As to TI using closed source drivers,that is the result of buying IP from other sources, something that most SOC suppliers do in one area or the other.

Gerald, perhaps, but it is a huge disappointment to me, and I am sure to many others out there.

This board to me screams low-end x86 killer, and squarely lands in the multimedia arena. A bit much for a NAS like system if you ask me, but surely would do a great job of it.

It will be interesting to see how the USB3 drivers shape up as well.

With the dual dsp's and dual m4's, video decoding should be nice..

It's not the classic 'musb' IP from a completely different manufacture.

According to this article:


Cortex-A15 performance is double that of Cortex-A9. Given that Wandboard runs at just at 1GHz and the X15 runs at 1.5GHz, I would guess that the X15 runs about 30% faster; however, the X15 has a dual 32bit bus, so the memory bandwidth is way higher. Also, the X15 also has dual C66x DSP processors, dual Cortex M4s and dual PRUs, so this board will be a screamer compared to the wandboard.

I'd be surprised if it did. I've been keeping up with the technology for many years now, and mostly only Silicon image ( SIL3132 most notably ) chip sets support port multiplication. However, in the last year or so I have not been keeping as close an eye on this stuff.

Id be pleasantly surprised though !

Well the Cortex-A15 includes full hardware visualization, which the Cortex-A9 lacks. If this new board with multiple Cortex-A15 and dual Cortex-M4 is reasonably priced it might used as a references board for an open source Linux/RTOS solution.

*) FreeRTOS on one Cortex-A15, GNU/Linux on the other
*) FreeRTOS on one Cortex-M4, GNU/Linux on the Cortex-A15 cores,...

anyone interested in something like this?

Wandboard Quad does have 64 bit memory bus.

P.S. I don't know who needs dual DSP onboard because TI definitely will not support them as should like it was for omap3/dm37. I'd better have well supported hardware video encoder/decoder rather than double general purpose DSPs without any software support

I think the feature set of the X15 is almost comparable to the
OMAP5432EVM (which AFAIR was originally planned to become
a PandaBoard 5):

http://www.svtronics.com/5432

So this seems to confirm the price range $200-400...

Do you mean there won't be any way to access and use the DSP
from Linux, or just that TI won't provide us with codecs and other
software goodies?

My understanding is that DSP Bridge and DSP Link have been
replaced by IPC 3.x (which has OMAP5 support).

http://processors.wiki.ti.com/index.php/IPC_Software_Options

I hope we'll have support for that on the new shiny board!

The bbb sgfx is one reason why I've found the minnowboard is so
appealing. While we (my company) are using the bbb, and its a great
board, if we needed something in a higher performance range and could
float the cost we've been eyeing the minnowboard due to its fully open
graphics stack.

If the sgx was easier to get working with yocto or mainline kernels we
might think differently but we've already sunk a few weeks of effort
into getting accelerated graphics working without much success.

Did you mean OMAP5 interface? The last I looked, OMAP5 support wasn’t complete and as you know I’ve been pushing for RPMSG/REMOTEPROC support on this processor and the only feedback I received was that support wasn’t going to happened anytime soon. To me, RPMSG/REMOTEPROC and SGX should be on TI’s high priority list or as Maxim said, this processor will end up just like the DM3730; great processor without any ability to use all the features. BTW, I believe IPC3.x is SYSLINK3 which is RPMSG. Once we have RPMSG/REMOTEPROC, all the video encoding/decoding together with codecs etc should pretty simple for TI to add and that would make this a fantastic product.

John

When OMAP3 came out, the only compilers for C6000 were expensive,
closed-source compilers. Now, there is support in mainline GCC for
C6000. As the BeagleBoard.org community, we have to work together to
enable use of the DSPs if they are of interest to the
community---there aren't any barriers in our way.

The TI C6000 does some amazing pipeline optimization, which seems to be
missing from the GCC compiler. Anyway, using CCSV6 is no big deal, but
support for RPMSG/REMOTEPROC on this processor is a big issue. The source
is difficult to follow and my guess is we would need input from the
original authors to do this work.

Why dont we get involved in linux-omap discussions on the topic? most
of the rpmsg and remote proc discussions do take place in kernel
mailing list. usually discussing in context helps move patches forward
since it makes it clear to certain maintainers that these things are
important and help community.


Do you have anything specific that you are concerned about?

I think the biggest concern of bb.org, is that we don't end up in a
similar situation to the omap3. Where dsplink/etc never went mainline,
thus 5 years later, we still need to run the 2.6.32 psp to even
utilize the omap3's dsp.

Just the classic.. burn me once... ;)

For the am57x, since the foundation rpmsg/remoteproc is mainline, we
should be in good shape... (fingers crossed)

From the datasheet, it looks like the SoC does not have dual ethernet MAC's. Instead it has an internal 3 port switch, two run off-chip to the ethernet ports and one to the SoC's MAC. This is a bit of a disappointment as I was hoping for true dual GbE MAC's.

Looking at git.ti.com/rpmsg/rpmsg, I don¹t see any support for AM572x
processors. Also, Beagleboard-X15 is to be released with Kernel V3.18 but
I don¹t see support for this kernel versions. Last I heard, RPMSG was
working on OMAP4, but not fully implemented on OMAP5, but this was a while
ago and perhaps this has changed. Perhaps Suman can give us an update.
Similar concerns about REMOTEPROC. What I know is that I have been pushing
this issue on the beta list and the only feedback I received was that
"RPMSG/REMOTEPROC was in a SW blackhole².

Based on the TRM, this processor looks extremely attractive, and we need
RPMSG/REMOTEPROC to take advantage of the powerful dual DSPs and dual
CortexM4s.

Hi Suman,

That is really good news. I’m guessing that V3.18 support will occur with
the push to mainline? Any chance that we will see support when
Beagleboard-X15 launches in Feb 2015?

John

The picture on  
http://www.elinux.org/Beagleboard:BeagleBoard-X15
looks great. 

But, I note that it does not show a heatsink or fan on the Sitara.

Is this just some "photographic license" or is this Sitara going to need
some proactive cooling?

Thanks,

Gerald added two layers to the PCB to act as a heatsink, so no additional heatsink or fan will be necessary. At least that is the plan.

Thanks. Let us know when you know.

As a comment, I could not find any on-die temperature sensor.
In dealing with FPGA's and other high power chips, having a way to
directly read die temperature has helped us solve all kinds of problems.
Please pass on to TI marketing, if you get a chance.

There are on die and onboard temperature sensors. Current boards have a heatsink only.

Did the heatsink layers work as expected?

Yes. They helped a lot. But crank everything up and it may still need some help.

Graham,
I had a quick look through the manual: http://www.ti.com/lit/ug/spruhz6/spruhz6.pdf
On page 4007 it states: "There are five temperature sensors on the device die."
