\ARM\ARMCC folder to be easily found by µVision. For me, I used C:\Keil_v537\ARM\ARM_Compiler_5.06u7 but it is traditionally just in the. For one it’s probably better to keep it with where it would normally be, with your The installation is straight-forward but I would recommend choosing a more suitable installation folder than the default Program Files (x86) area. A tool which understands all these filetypes is going to be needed, such as 7-zip under Microsoft Windows. Here we can find the different releases of version 5 (and 4 if you want to go that far back). A registered account will be needed if you haven’t got one already.Īt the time of writing, the download can be found at: Although is eager to point you towards the latest copy of Version 6, we have to go to the Arm Compiler 5 (ACOMP5) download area. How to install another Arm compiler in µVisionįirst of all, we must download the compiler we wish to use. We can put compiler 5 back into our latest µVision environment with a little work. For the unexperienced, this can be a little daunting seeing a demonstration project which should run ‘straight out of the box’ instead fill your screen with errors and warnings.įor those who have their existing project but have a clean installation with the latest MDK, it's normally imperative to get back to a usable state with the previous compiler to show all is well. It has a number of differences, but the main advantage is moving to 64-bit on the compiling host.Ī Functional Safety (FuSa) qualified version of both compilers are available but only version 6 is being carried forward.Īlthough silicon vendor packs are migrating to using the new Compiler version 6, there are still a number of examples and demo code that expect version 5. Version 6 (armclang) jumps to the LLVM compiler infrastructure to take immediate advantage of the work already done in that area and bring it to Arm devices. The version 5 compiler (armcc) has been developed over many years and matured into a very reliable system. For new projects you should use the version 6 compiler. While the safety version is under long term maintenance no new features will be added. Version 6 is meant to be the successor to 5 but either are still valid to use. They are two separate tools, each with their own architecture and version numbering. Even more so now that version 6 is being renamed “Arm Compiler for Embedded". In some cases, projects and existing code still need compiler 5.Ĭalling the compiler version 5 and version 6 can be a little misleading. In previous versions both compiler versions 5 and 6 have been available as part of the installation. This isn’t an oversight, just a gradual progression to give a strong prompt that version 6 is the way forward. To keep things lightweight not all legacy tools are included ‘out of the box’.Īs of µVision version 5.37, it no longer ships with Arm Compiler 5. Like with most software tools, Keil’s µVision MDK software evolves over time to keep up with latest trends and technologies.
