ARM development - KEIL (MDK) vs. IAR (EW)
alemannia
I have browsed the web for recent experience reports on KEIL MDK and IAR
Embedded Workbench. The posts that I found are quite outdated, so I thought
I start a new thread here.
I will need to buy one of those products sometime soon and I am curious
about your experience with one OR/AND the other. What do you like about it,
what are the weak points? I am completely aware that this questions is a
little bit like "iPhone" vs. "Android" but I find it hard to decide and any
suggestions will help.
There are free (size limited) version of both environments and I am having
a first look, but this takes time and additionally I need to buy a JTAG
probe to get the real feel of the IDEs in action.
I appreciate your input.
Cheers.

I'd add Rowley's CrossWorks to the list. I don't believe that they offer
a time-unlimited free version but one does get 30 days to evaluate the
full suite. It also supports quite a range of JTAG adapters, including
the relatively inexpensive ones from Olimex.
Likes: Works pretty well. Has include files/packages for more ARM-core
processors than I knew existed. Supports serial wire debug (SWD) mode.
Dislikes. Wish that the text editor had a vi mode!

I worked for a company that used the IAR for a while and the optimisation of
the code that it produced was absolutely rubbish compared to the ARM
compiler (that every previous company had used).
They soon swapped!
The ARM complier isn't that expensive. For a single seat you will not
regret the small up front extra costs

I can't comment much on either of these, but you should be aware that
there are a number of other alternatives. Someone else has mentioned
Rowley - I'd add CodeSourcery and Code Red to the list of tools you
should try.
You really should try out the tools yourself - asking other people will
just get you personal opinions. You can get a good impression from
using them without a board or a jtag debugger - they all have some sort
of simulator, which can give an idea of how the debugger works and its
features (though obviously no impression of the real-world speed).
You are going to be investing a lot of time, and possibly a lot of
money, in these tools - it's worth spending some time picking the right
tool at the start.
alemannia
thanks for your answers so far. I think at the end it's really a matter of
personal taste.
I have been working with the ARM compiler (stand alone with Lauterbach
JTAG) for quite some time and that's why I will opt for the KEIL package, I
think.
I just wanted to check, if there is a killer argument in favor of IAR.
IAR:
+ USB stick based licence management. The license is not linked to your
PC.
+ Support for Cortex A8, which will never be the case with KEIL.
KEIL:
+ ARM compiler.
As to the other tools, I tried CodeSourcey and it's interesting although I
am not sure about their JTAG support and the whole 'Sprites' approach. Also
CodeSorcery has been bought recently by Mentor. They will certainly start
pushing their own products (Nucleus, etc.) through this channel now.
Anyway thanks again for your answers.

I felt a litle ripped off when they initially said unlimited updates, then
upped the version number and therefore wasn't eligible for updates!! :-(
Also in my case limited by 2 hardware breakpoints.
John Devereux
Surely that's a limitation of the ARM7, rather than the toolchain?

You also, undoubtedly, have your own way of "doing things" and
you want to see for yourself if the tools support, encourage
or *discourage* this. No one can "tell" you that...

Which ARM compiler are you talking about ?
ARM PLC sells Keil, are you talking about Kiel ?
Are you suggesting ARM RVDS ??
The question was about IAR and Keil, are you also adding a third
compiler to this mix ?

Same with IAR + Segger Jlink + STRM912 CPUs
That's most likely a processor limitation, not a tool's one.

If you are used to ARM/Keil, then that's a big argument in favour of
continuing using it.

I expect that most debuggers work in a similar way, using some sort of
"proxy" program that is specific to the hardware interface. They might
hide it better, but it's a common way to modularise the debugging system
and let it support a range of hardware debuggers. Tools like Lauterbach
that connect by a network are sometimes a different matter.

I haven't noticed any change in CodeSourcery since Mentor bought them,
but perhaps it will over time. But the core tools - Eclipse for the
IDE, gdb debugger, and gcc for the toolchain - are all open source, and
safe from too much Mentor-specific influence.

Hi hamilton,
As far as I know there is only one "ARM compiler" - armcc. It is the same
compiler in the KEIL MDK package and in the ARM RVDS package. The only
difference is that the KEIL package has some flags disabled. It doesn't let
you compile for the ARM application processors Cortex A8/9 for example.

LOL, and the rest of us knows that how ??
So far the discussion has mentioned 5 ARM (processor) compilers.
So, the war (flame) begun has !!

The one sold by ARM.

Isn't its current name Realview?

Yep. I have no experience of the Kiel so I can't do a comparison.
I can only compare IAR with ARM and TIME there is no comparison

Yes I'd forgotten that.
Is the compiler "branded" Kiel the same as the one that ARM used to sell
using their own branding?
tim
David Brown
As far as I know, when Keil was a separate company, it had its own ARM
compiler completely independent of ARM's compiler. When ARM bought
them, I presume that they standardised on one and merged the good bits
from the other - but that's just a guess.

The Keil compiler will not support any cores... only MCU. The RDVS
supports al the cores. That is the differentiation between the RVDS and
Keil.

And accurate,.
Keil had their own (very good ) ARM7 C compiler.
When they were acquired by arm the dropped their own compiler and put a
cut down version of the ARM RVDS into Keil uVision.

Hi Chris, I suspect you are using your own private definitions of words
again... :).
If it supports a particular MCU with a cortex-M3 core, say, then it
supports the CM3 "core", doesn't it?

No I am using the definitions off the Keil ARM distributor
documentation.
The ARM RVDE supports al the ARM cores.
The Keil uVision Arm compiler only supports ARM/Cortex MCUs not the
cores.

That is due to the market these things are sold into. The entire
MDK-ARM product is based around a Device Database which contains
details of not only the core but the memory maps and peripherals of the
device. It is being in this database that is classed as 'supported' for
the product as it means that the libraries that are supplied with
MDK-ARM will just work(tm).
RVDS is more aimed at SoC bring up and doesn't have such a database.
As has been repeated said the compiler in MDK-ARM is armcc. The only
difference is that some flags have been disabled so it can only be
configured to tune code for ARM7,ARM9 and Cortex M and R profile cores.
