I want to create a project with the gnu compiler. I've seen in the keil website that I can find the startup.s file in this directory: C:\Keil\ARM\GNU But I don't have this directory and I don't find startup.s file for my luminary microcontroler (to comple with gnu compiler). If someone can help me. Tell me where can I find this file. Thanks
gcc no longer supported by Keil. You have to go the other route, i.e. locate the ARM version of gcc, and pick up startup files etc from that site, or see what forums you can find.
The full CD image from each Luminary devkit is available for free download from the Luminary site:
www.luminarymicro.com/.../
For each kit, there are two GCC-based versions:
EKC - CodeSourcery; EKT - Code Red.
If you buy a luminary kit, the Code Red is unlimited for use with that kit after free registration.
There is, of course, also a Keil version - EKK.
Choose one, and use it - I don't see any point in trying to mix-and-match GCC with Keil:
