ARM development - KEIL (MDK) vs. IAR (EW)

Started by alemannia April 2, 2011
Hi all,

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 The posts that I found are quite outdated, so I thought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.

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 tim

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.
Hi,

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.

Surely that's a limitation of the ARM7, rather than the toolchain? -- John Devereux

+1 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 ? hamilton

Same with IAR + Segger Jlink + STRM912 CPUs That's most likely a processor limitation, not a tool's one. -- Roberto Waltman [ Please reply to the group, return address is invalid ]
