 I have successfully run Linux one and other core running barematal

 Possibly Run FreeRTOS instead of barematal application.

 Run Linux and FreeRTOS on hypervisor.

 After completing "FreeRTOS on one Cortex-A15, GNU/Linux on the

 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.

 anyone interested in something like this?

X15 is a different beast for different purposes imo. I still like the form

 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.

Don't get me started on that. Tried that for years and never could get it

Well in our case ntpdate + ntp.pool.org works fine. Most of the time.  But
I've also thought about many external work arounds, which really renders my
gripe moot. An msp430g2553 for instance doesn't cost much more than an RTC,
and can serve multiple purposes . . .

The on die RTC has been rendered unusable. It has no clock. External RTC is

The only real thing that bothers me that I can think of offhand. Is having
an on-die RTC that effectively can not be used. However, there *are* both
hardware, and software work arounds. Depending on how early you need the
clock to be accurate.

Not even sure if that is listed as an errata item, but . . .

Non of that has had much if any effect on any of our projects. Which my
buddy ( the EE in our projects ) read the errata prior to release. He
expressed some concerns early on, but in the end they have had no effect on
our projects.

They are what are called X versions. As was the case on the BBB, these are
the same devices as the production release versions.The same devices will
be used on the TI EVM.

All issues are listed in the process errata. Any issues that may be fixed
have HW workarounds already in the design.

This is getting confusing... as far as I know "ducati" properly refers only 
to the dual cortex-m3 subsystem, although somehow it seems to have acquired 
the secondary meaning of the overall video setup it manages.  Applying that 
to the omap5 or vayu however feels misplaced since it has no "ducati" 
subsystem: the dual cortex-m4 subsystem replacing it is called "benelli".

IPC should be pretty easily portable; which is also evident from the fact 
that IPC 3.x supports tci6638, omap-L138, omap5, and vayu 
(dra7xx/am57xx)... which are pretty different processors.

IPC is used for communication between cores on the chip.  It has no 
relationship whatsoever with PCIe.

You're confusing a few things. HDVPSS handles (uncompressed) video in/out 
streams and compositing, and is basically a predecessor of Vayu's 
VIP/VPE/DSS (but together in one subsystem with one VPDMA instance). IPU is 
the dual cortex-m4 subsystem, successor of the dual cortex-m3 subsystem 
(aka "Media controller") that's on omap4 and dm81xx, which is used to 
manage the video subsystems. I've never looked into what tasks it handles 
exactly, and that may be platform-dependent, but it does have a close 
relationship with ISS if present, and probably glues video in/out streams 
onto IVA-HD (aka HDVICP2) for en/decoding.

The closed firmware blobs are annoying, and could probably be replaced with 
open source code if interaction with IVA-HD can be figured out and someone 
cares enough to put in the effort.

The am57xx is a "dra74x", just like omap's prior. The DR74x is a
automotive specific designation, whereas the am57xx has the
sitara/catalog (wide market) branding..

Same hardware underneath, just a different marketing name..

As I understand ,

2) dra74x only support ipc version 3.x , compatible with linux kernel rpmsg
3)pci-e is nothing with Ti ipc
4) Ti implement ipu/hdvpss on their m4/m3 with BIOS/rtos ,this is depend on

About the pci-e on am57xx should have some difference with dm81xx
at least , if am57xx same as dra7xx , dra7xx have 2 pci-e subsystems .while
dm81xx only have one

You can contract Ti with Dra74x TRM ,maybe NDA needed ,but this should be
the  right way .

The revision that's in the DM814x certainly has some fun ones...

   - *Advisory 3.0.6* - Data is corrupted is burst accesses (e.g. EDMA) are
   performed that do not start and end on a 16-byte aligned boundary.  Any
   access which can't satisfy that constraint must be performed using single
   accesses.  (Doing that with EDMA is still possible but requires some
   creative self-chaining configuration.)
   - *Advisory 3.0.7* - A failed non-posted transaction doesn't set the
   status bits it's supposed to. You can still find the raw PCIe header of the
   response in some register and parse it yourself.
   - *Advisory 3.0.10* - PL_ACKTIMER register may only be changed while in
   Gen1 mode. Changes made in Gen2 mode corrupt contents.

I really don't understand all this fussing about documentation.  You'd
think that being well-supported by software adds value to their IP, and
public documentation is generally rather important for that.

(The crypto accelerators are in an even worse position: TRMs often don't
even admit to their existence, not even those for which linux drivers have
been publicly released. *rolls eyes*)

Add on boards is TBD. I do no plan a PCI board per se. I am looking more

I am looking more towards more functions per board that one connector.

You are correct. And all of those that were made public, evidently, should
not have been.

It's worth mentioning that various other reasonably recent TI SoCs have a 
PCIe subsystem with public documentation, e.g. Netra (DM816x / AM389x), 
Centaurus (DM814x / AM387x) and the Keystone series. They all have slightly 
different versions of the same Synopsys DesignWare Core, so it seems likely 
the one in AM572x will be similar too.  (Of course I could be wrong there)

If you feel so strongly about this issue, then direct your efforts to make
a difference. Express your views on IMGTEC developer forums or contact
your TI rep or express your views on TI¹s E2E. We all agree that the lack
of Linux support for IMGTEC IP is a big issue but no one here can make a
difference.

TI is waiting for approval from the IP owner as to what can be put into the
document. This was a way to get it out sooner and not have to wait on the
IP owner.
It will be included in the final release.

Look at the recently submited mail box subsystem.

Please share a link


http://marc.info/?l=linux-omap&w=2&r=1&s=mailbox&q=b


Yes thank you, I did not saw my mail reaching the mailing list.
The recently merged generic mailbox subsystem and the omap mailbox
driver are the foundations for remoteproc.
All in on the way. This is a big step forward for all past and future ti
soc.
http://marc.info/?l=linux-omap&m=141505601225611&w=2


Posted on mailing is just step #1.
 here are other steps needed:
- Device Tree maintainers need to ack - that takes a bunch of time and 
sometimes depends on the polarity of solar flares and grace of a bunch 
of overworked devicetree maintainers dragged in all directions.
- Mailbox maintainer need to ack as well - which means the mailbox and 
rproc framework cannot conflict against other SoCs..

- All of these must finally be accepted by Linus.

Just coz it is posted around 3.18-rc4 requesting dt reviewers indicates 
it probably will miss 3.19 window, 3.20-rc1 is the next opportunity (umm 
5 months away)? yeah - it will be nice to get additional review help on 
the linux-omap mailing list so that maintainer jobs are a little 
easier.. all contributions welcome. we will continue to push from our 
side ofcourse.. but kernel.org support takes time...

Umm, slightly different. Poulsbo also included the 2d engine, so with
out GMA500 driver, no "DISPLAY PERIOD..", in our case we can get video
working on mainline, it's just the 3d offload we need the sgx bits
for..

 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?

Feb 2015 is too early to have all the remoteproc/rpmsg pieces make it to
upstream, so for now the 3.14-LTS based TI kernel is the latest where
everything is in place.

 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.

One should be able to directly download the C6000 compilers at
http://software-dl.ti.com/codegen/non-esd/downloads/download.htm#C6000

The rpmsg-ti-linux-3.14.y branch in the above tree is the feature
integration branch for rpmsg/remoteproc and does support all the
processors on OMAP4, OMAP5 and AM572x/DRA7x. The AM572x support should
be present through the am57xx-beagle-x15.dts file (its been sometime
since I pulled the required platform branch with any updates to this).

I am in the process of pushing all these features/patches upstream, but
it will mostly be sometime next year before all the patches and their
dependencies will make it into the upstream kernel, so until then have
to rely on a TI tree.

Suman

I guess if enough users way in and convince IMGTEC to support Linux
mainline, they may rethink their reluctance to support the open source
community. Post your comments on:

Maybe not as bad as you think. I had a discussion on the linux-omap
mailing list and TI have RPMSG/REMOTEPROC working on the AM572x processor
and will push this to mainline early 2015.

 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.

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.

 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.

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?

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.

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)

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.

Did you mean OMAP5 interface? The last I looked, OMAP5 support wasn¹t
complete and as you know I¹ve been pushing for RPMSG/REMOTEPROC support on
this processor and the only feedback I received was that support wasn¹t
going to happened anytime soon. To me, RPMSG/REMOTEPROC and SGX should be on
TI¹s 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.

Re: [beagleboard] Re: BeagleBoard-X15 - seriously? :)

[Chris Morgan]

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.

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).

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

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...

John Syn,
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'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 !

There is eSATA on the board. I do not know if it supports port multipliers.
That would be a TI question.

I did not notice the eSATA on the specs that I've read so far. However
assuming this board does have an eSATA port on it, does this port also

According to this article:

http://www.arm.com/products/processors/cortex-a/cortex-a15.php

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.

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

Re: [beagleboard] Re: BeagleBoard-X15 - seriously? :)

[William Hermans]

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.

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.

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:

http://www.contextengineering.com/split_body_enclosures.html

Pricing is pretty reasonable:

Nice work Gerald.

[sa_Penguin]

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...

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!

Yeah, that gnu project has been around for awhile, they have only
updated the list of boards..

I thought this we a little interesting..

imgtec must be now desperate for new business, as they provide the isa

with nobody contributing recently:

Definitely not one of those. Look at what it has on it and make a good
guess.

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..
