Yagarto - free ARM C compiler

[bigtoy]

I don't want to make this sound like an advertisement or anything. But I've recently switched from IAR to the new version of Yagarto http://www.yagarto.de/ and I'm a lot happier. Sure, Yagarto is a bit more work to set up; it's not all wrapped up and pretty like IAR is. But I'm pretty happy - I'm having a lot fewer unexplained things happening in my code, and it's nice to have a lot more control over it all. Just a thought for those considering an ARM C compiler.

What are the main differences or more the main advantages towards other free ARM compilers like ARM GCC?

Yagarto is ARM-GCC based (and Free)
Last i checkked it was a nice package with build in OpenOCD support via Eclipse CDT

I'm using Codesourcery Lite , as i need Linux support.

But Yagarto is recommended in the windows world (even by Martin Thomas , who made WinARM)

It's a free and legal compiler for ARM , and well suited for most hobby and probably also commercial products.

But it can't produce as compact code as IAR

The reason I switched from IAR was pretty simple. I'd been using a <cough> evaluation version of IAR to try it out, and had a problem in my software where the processor seemed to be behaving strangely. I sent some code demonstrating the problem to tech support for the processor (a cortex-m3) and they determined it wasn't a processor problem at all - it was incorrect code generated by the IAR compiler. Oops! From there I went to codesourcery g++, and from there to Yagarto. I have spoken to other IAR users who have experienced similar problems, although I suspect those problems might possibly have been fixed in the latest versions. Of course no compiler, including the GCC-based Yagarto, is guaranteed perfect, but I've been happy and haven't seen any issues. As Mega32 points out, it is for Windows only.

mega32: Assuming both have linux support, which one do u suggest, Yagarto or Code Sourcery? U may just consider the command line tools of both.

I'll let Mega32 give his opinion, but I'll give you mine.

I've used both CodeSourcery and Yagarto. As Mega32 pointed out, Yagarto is Windows only, so that might be a factor for you.

Yagarto and CodeSourcery Lite are very very similar. They are both distributions of GCC, along with the various GCC libraries. They are both command-line based. You can pay CodeSourcery (Mentor Graphics actually) for a GUI / IDE with nice debugger etc, or you can do it yourself using Eclipse or what-have-you for Yagarto.

I had been using CodeSourcery for a while, but they only release a new version of "lite" a couple of times a year. So depending upon when they release it versus when you grab it, it might be current or it might not be. I switched to Yagarto simply because Yagarto had done a new release, rolling in the latest GCC bugfixes, latest processors support, etc, whereas at that time CodeSourcery was looking a bit old. In terms of use, code generation, bugs (I haven't come across any), etc, I haven't found any difference between CodeSourcery and Yagarto. It's trivial to switch back and forth between them - they're both GCC. In Windows just change your PATH to point to one or the other - everything else (makefiles etc) can stay the same.

Thnx for the review. So from what I understand, u say I can switch from one to another whenever a new version of either comes out. I think I'll stick to CodeSourcery as I'm using both Windows and Linux.

Hi ARM users,

Does ARM uc is available in real dip package not the dip module?

I actually think bigtoys ansver is 90% equal to what my ansver would have been.

I am basically using codesourcery (lite) , because i'm dualOS'ed ... And have to.
Especially after they have been bought by Mentor (hhrrmmpfff) :-(

But they are (were ?) the company that is/was being funded by ARM , to develop
arm-gcc. And does a nice job.

Michael @ Yagarto , is actually doing an even more impressive job.
Maintaining his toolchain almost alone.

The path changing (changing toolchain version) on linux is done , by/via symlinking the wanted toolchain to my $HOME/arm-gcc directory.
Fast, Efficient and Easy

AFAIK NXP is the only one that has one (announced one)
