GNUARM, Keil, Iar, Rowley

Started by djordj April 14, 2007
I'm starting a new project with ARM7 core processors and I need to 
evaluate these toolchains (with associated enviroment).

Is the GNUARM toolchain (debugger) good and reliable, or do I need to 
buy some proprietary product?
I'm looking for some advices, info and experiences about those.

Thanks a lot.

As far as I know the GNUARM debugger is just GDB, which is reliable but somewhat limited by modern standards of usability. I personally use Insight as a GUI to GDB, but this is not always so good on a Windoze host. There is some build information on the following page: http://www.freertos.org/portlpc2106.html with regards to this (go to the homepage to see the menu frame). For an open source solution people are using Eclipse more and more, but I have yet to overcome a few hurdles with that. Rowley provide a professional quality IDE for GCC at a very reasonable price. The FreeRTOS.org site contains some sample projects for all the compilers you mention (the old Keil compiler included, the new ARM/Keil combo is not yet in the download). You could get eval versions of each and try out the projects to get a feel for each. -- Regards, Richard. + http://www.FreeRTOS.org A free real time kernel for 8, 16 and 32bit systems. + http://www.SafeRTOS.com An IEC 61508 compliant real time kernel for safety related systems.

The Rowley software is very good, they use the gcc compiler with their own IDE and debugger. Leon
Leon presented the following explanation :

Yes, it's at the top of the list, due to its low price. As it uses GNUARM, I suppose that I can use even eclipse with a JTAG bridge, but I'm very scared about debugging possibilities. As for Keil & IAR, I can't figure out (as now) how much do they cost: I think some thousands dollars.

Just a little update. During this weekend I've bring up my eclipse installation (I usually use Eclipse for Java and C/C++ programming - with CDT) and create a small GTK+ Win32 project. I've found that GTK+ uses C language (not C++ like other GUI toolkits), so I think that this could be better in order to build a simulated enviroment used to develop the embedded application. Now I'm using MinGW 5.x GCC compiler and make, so I suppose that the step to ARMGNU should be small. The only think I'm concerned still remains the GDB interface, but I've read on the net that Eclipse con be used (quite easily) with OpenOCD and other JTAG interfaces (or so I hope!).

If you want arm gcc along with a ready-to-run Eclipse environment with debugger, look at www.codesourcery.com . You can get a free gcc setup, or buy a subscription to the gcc with Eclipse for the debugger front end. I haven't tried their ARM tools, but I use their ColdFire tools (although I actually prefer command line gdb over Eclipse for a lot of my work). A big advantage is that Code Sourcery are the official maintainers of these gcc ports, so you get the latest improvements to the compiler, and if you have problems or questions, their technical people know what they are talking about! mvh., David

Another place you can get these tools is www.gnuarm.com. There is a Yahoo group which offers support, http://tech.groups.yahoo.com/group/gnuarm/. There are some differences between the CodeSourcery tools and the "official" Free Software Foundation sources. So you can choose your poison.

Thank you for the link!

Yes, there are some differences - the free CodeSourcery tools have pretty much the same backend as the next version of the FSF tools will have, while the subscription versions have the same backend as the version after that (the frontends are all much the same, although some CodeSourcery developers work on the frontend and middle "end" too). CodeSourcery are the official maintainers of the ColdFire and ARM ports of gcc. So their versions are always ahead of FSF versions - it takes a long time to get changes through the FSF bureaucracy (for good reason - it's a complex system, and they don't want gcc to get broken by poorly tested contributions). So if you want to be able to compile your ColdFire code with a "-mcpu=5213" flag for the MCF5213 processor, you can download CodeSourcery's binaries or source tarball now, or you can wait a couple of years for gcc 4.3 to be officially released. Paid subscriptions get faster access to the latest developments, along with debugger improvements and Eclipse builds (if you want to use it). Pay some more, and you get professional level telephone support rather than just mailing list support (the developers are active on the list). I haven't used the ARM, but my understanding is that the same thing applies there. Of course, there are many reasons for wanting to stay with the standard FSF versions. But I'd just like people to be aware of the CodeSourcery option, whether you are wanting the free version or to pay for a subscription version. I don't know how the Rowley ARM tools compare to CodeSourcery's, and I don't know how much Rowley contributes back to the FSF or modifies the compiler themselves, but I *do* know that CodeSourcery know what they are doing with the tools.

Have you used ddd? M.
