There's something I'm not clear on ... is it possible to have both a Keil Tools-based target and a GNU Tools-based target in the same project? I tried it, and it seems that because of the substantially different Startup.s for Keil vs GNU, it's not possible to do this. E.g. I had a project with only a Keil-based target. In this project I created a new / additional target for use with GNU. Building the GNU target failed because of lots of syntax errors in Startup.s (which came from a Keil project, of course). So In the GNU target, I removed Startup.s and replaced it with the one from the GNU Blinky, so that it would build under GNU. But now it fails under Keil because of the same problem ... Are the files in the filelist always the same across all of the targets? I.e. a project's filelist is not target-specific? Thanks,
You may add two files STARTUP_GNU.S and STARTUP_Keil.S to your project. The config Wizard will still work. We will take away the filename limitation in the next uVision version, so that you no longer need to rename it. This was introduced, because the tools itself are using the filename to derive a module name. If a project has two identical module names, it cannot be linked or debugged.
By the way: the Config Wizard is based on tags in the source file only and might be useful also for other configuration files (like RTOS config). The features of the Config Wizard are documented in the uVision User's Guide, uVision3 Utilities, Configuration Wizard.
