Hi, Stu.
Thanks for your reply. You were right regarding to newlib question. I just had to implement a pair of stubs to remove these annoying warnigs. Also, I solved the debug question with Eclipse, it was due to a bad debug configuration regarding to source files.
Regarding to the size of image, I didn't make any progress. I was already using the flags you mentionned and I can build with -O2 at the most, but not with -O3 (I assume that -O3 is equivalent to -Ov100 flag of VDSP compiler). With VDSP and -Ov100 I get a small enough image that fits in the 32KB of RAM , but I have to use the GNU toolchain too.
My main doubts now are:
- Is there a big difference of performance between GNU and VDSP compilers?
- Should it be possible to use the scratch RAM for code?
Thanks again for your help,
Bonifacio
