Compiling and working with the files already in the project works just fine and was easy enough to understand. Have a look at this page: When I put that in the makefile, I get an error of not being able to find libnosys.

The overflow was bytes on this one. In GCC the flag '-Os' will turn on all size optimizations.

Again, using the builtin gentoo crossdev arm toolchain. I just recompiled newlib without the syscalls and now this is what I get: I suggest you try with a plain example like blink that does not print anything to the display and start from there by adding things and watching how the size grows.
You should also try playing around with compiler optimization and see how much this can give you.
nedlib The best is to check the map file to figure out what is eating up the memory. Stack Overflow works best with JavaScript enabled.
Also check your map file to see which parts of the program is using the most space. Sign up using Email and Password.

Have a look at this page:. I can get small programs to compile just fine. The last rule that applies the patch doesn't work, but even if it did I can't help but feel like I'm doing this wrong. Try to nnewlib using printf or use iprintf restricted to only integer numbers instead to save code space.
You are still overflowing both RAM and Flash. What happens if ndwlib just remove the link to nosys? I tried downloading the sourcery codebench as described in one of your getting started guides, it didn't specify version so I grabbed the latest. Asked 5 years, 10 months ago. Replied Dec 308: Improving the question-asking experience. Replied Dec 306: The other problem is that the final output is too large to fit in the memory available on your target.
When I put that in the makefile, I get an error of not being able to find libnosys. For instance, this lines shows that it allocates newlig 6 kB 0x16d8 bytes for vfprintf.
Post as a guest Name. The forum system won't let me attach the map file Error You aren't permitted to upload this kind of file. Nothing seems obvious but then I've never looked at one of these before Note that this map file is from an attempt to compile a stock inttemp from the 2.0. demos. I am not sure why it does not compile when you use the codesourcery library. This is a common problem when trying to neslib code using 'printf' in small embedded systems.
