The similarity between the project contact address and your user name on 
this forum lead me to suspect that this is an attempt at self promotion, 
and might be considered Spam. By all means introduce your project to the 
forum (in another thread), but until it has been proven useful by the 
community, I am not sure that it deserves a place here.

Moreover the product seems somewhat immature and the website's use of 
English does not inspire confidence. It says: "CooCox Builder V0.1 can 
only build and has not been tested completely, it only for the users who 
always give attention to us". I have no idea what that comment means!? 
It looks like the kind of nonsense that comes out of an automated 
translator such as Babel Fish.

Hi friend,
    Maybe there is some truth about what you said, but CooCox CoBuilder 
has only released its 0.1 version. It is all for free.
    I have used CooCox CoBuilder myself, it is really distinctive, its 
repository is completely organized by components. Maybe it is ordinary 
even not good compared with other mature IDE right now, but CooCox will 
be absolutely a very useful and different set of development tools for 
ARM Cortex M3.
    Just have a try, please.

Free dose not make it a useful resource - and that is what this thread 
is for.

It deserves a place in this thread when and if large numbers of 
developers have used it and it has proven to be useful. Until then take 
your project to a different thread for discussion; that is all I am 
saying.  Note that in all this time that it has not made it to the front 
page.

Also you caginess about your relationship to this project (pretending to 
teh a user not the developer) does you no service.

Hi Cliff,

I completely agree with you: this is self-promotion.

This product may be free (as in "beer"), but it looks like it is not 
free (as in "speech")!

Beside the OS itself and the adapter schematic, nothing is disclosed.

The site's "About us" section does not give a hint on who is behind 
this, and a quick WHOIS search directs you to China...

I have found many forums where this project suddenly appeared using 
self-promotion.

My advice is to be very careful about this product, because of the 
methods used for promotion, and because of the ambiguity on "free"...

Hi Cliff and squonk42,

You guys are right. I did some self-promotion on my own products. I am 
sorry for all the inconvenience aroused. As CooCox products are 
emerging, propaganda is part of what it takes to achieve mature and 
well-known software. As the CooCox team is dedicated to perfecting its 
products, we have faith that all the software provided is and will 
become more reliable in the near future.

Thanks for your precious advice. I will take that into consideration.

Hello!
While you vanities on who what and why present this product, I just 
tried it. And I must tell you that for me
he has a future in GNU Embedded community. Do not know how they do it, 
but it will not manifest and there peaceful
use of MAKE for example. Get to test the software available free of 
these boys and girls, and then decide what is and support him or not 
endorse it!
When something new appears, it is said that it will be endorsed as such 
in time. Respect the work of the people are not gods to judge them!

My objection was only with the lack of honesty and transparency, and the 
use of this particular thread rather than one of its own.  Since it was 
so obviously self-promotion, treating the community like fools who would 
not notice or be concerned is insulting.

When something is proposed for a test and it is Free, there is nothing 
offensive or stupid to bother to make it look or test! No need to argue 
their opinion about who can do what in the forum or at all! If what is 
presented does not cause feedback does not sound or is not impressed 
anyone, and will remain unanswered!

You are entirely missing the point!  This is a permanent thread for 
resources that developers have found sufficiently useful and widely used 
enough to warrant bringing to the intention of other developers.  This 
product does not meet these requirements - it simply belongs in another 
thread; a point I have made more that once, but that Anny Lee has chosen 
not to do.

Would have been better to look at the topic and to understand what you 
write! Each software subject undergoes development, both in terms of 
development and to its users. For some of them even stopped maintenance, 
so there is no validated or insufficiently popular, and developed or 
abandoned. Stop the subject of misrepresentation.

Yes, you should do that.  The difference is proven resources that 
hundreds or even thousands of ARM developers have found useful over 
time, as opposed to some work in progress currently used by perhaps a 
handful of people.

If it had not been for the blatant attempt to deceive (and this treat 
the community like fools), this product might warrant serious 
discussion.  Start your own thread on it and I will gladly engage 
constructively; but this is not the place.

I note that since its first mention here, the web-site has been improved 
vastly - to the point that it is not even clear what this product is, 
which was not the case previously.

Regarding independent recommendation, a user who registers just after 
Anny Lee's last post and has only ever posted in support of Anny Lee to 
this thread does not count, since in all likelihood, you either are Anny 
Lee, or an acquaintance.  It would be interesting to hear from someone 
who has been registered here since before this discussion who is using 
this product.

Unfortunately, you continue to be made to an investigator and judge 
people! Nobody requires you this. Would have for himself to draw 
conclusions.
And what are you told people in the forum once in topic GCC saw that 
advertise IAR product? Look at your top post.
Become annoying people, so let me stop this meaningless argument!

SevensAndNines.com is hosted by IAR but is nonetheless a vendor agnostic 
resource.  It provides information and articles on ARM based devices 
from multiple vendors and a community forum. I neither promoted IAR 
products nor do I work for IAR.  The comparison with your post does not 
stand up.

Probably deserves adding, but there should perhaps be some guidance on 
how one might choose between this and the 7 other bare-metal GCC-ARM 
toolchains already in the list.  What value is added, or what host 
platforms does it run on for example?  They are all after all built from 
the same source (version differences aside).

It is clearly still available: http://sourceforge.net/projects/yagarto/, 
but perhaps obsolete and not recommended for new projects.

It is certainly encouraging that ARM Ltd. has taken on maintenance of 
GCC for ARM micro-controllers https://launchpad.net/gcc-arm-embedded

Very good & compact tutorial to get STM32 running from a low level point 
of view. Think makefile & build scripts:
http://pandafruits.com/stm32_primer/stm32_primer_minimal.php


I've been using Qt Creator 3.0.1 as ide (for avr stuff GCC & makefile) 
but you can easily use it for ARM also of course.

http://docs.platformio.org/en/stable/ide/qtcreator.html

platformio also has lot's of ARM & AVR stuff, among which are 1100+ 
libraries.

Also mbed.com if you like the "cloud" stuff (Which I don't).

Under OS options I would add ChiBios at http://www.chibios.org/ it is 
available both under the GPL and commercial licenses.

It has ports to a variety of processors and many examples.  It features 
two different OS options (RT and NIL) and a very full option HAL. A 
comparison of RT and NIL is located at 
http://www.chibios.org/dokuwiki/doku.php?id=chibios:articles:rt_vs_nil. 
NIL in its max config takes about 1k so is usable on just about any mpu 
yet has many adavanced features as noted above.  The creator Giovanni Di 
Sirio is very active on the forums.

As an added bonus (to me at least) is that benchmarks are encouraged 
unlike most other RTOS.

I'm not involved in development (outside of the C++ wrappers, which is 
user supported) just a happy user.
