Hi everybody I have used an example problem and used my functions to place in the ram after calling it main , it isnt working..........(Iam working on ADuC7026 processor). #define MUL_hi(a, b) ((a*b)>>16) #define MAC2_hi(a, b, c, d) ((a*b + c*d)>>16) inline void fft_rescramble(int * x_vector, const int LENGTH); register unsigned int R15 asm ("pc"); void Ram_Function(int *end) __attribute__ ((section (".fft_ifft_func"))); void fpfft(int * X_real, int * X_imag, int * x); void fpifft(int * x, int * X_real, int * X_imag); void Ram_Function(int *in_buf) { int X_re[256],X_im[256],re[256]; fpfft(X_re,X_im,in_buf); fpifft(re,X_re,X_im); } Thanks Hameed
I haven't solved the linker problem yet. What I did was define a funtion (with the same prototype) to be in a RAM section, and just copied the real function from .text to RAM. Since my function is assembly language I was assured that the internal references were correct. It works fine, but I wish I knew what I'd done wrong with the linker script. Having spent $$$ on the GNU tools (with Keil debugging capability) just prior to the release of CARM I couldn't really justify the cost of upgrade to my superiors. CARM would ease this problem, but introduce others of its own.
Having spent $$$ on the GNU tools (with Keil debugging capability) just prior to the release of CARM I couldn't really justify the cost of upgrade How much time will you spend trying to work around a problem a tool upgrade would fix? How much is that time worth? (Rule of thumb: 2.5x your salary expressed as an hourly rate.) What are the risks of delay in the project, and how much would that cost? The cost of software development tools is usually a pretty minor factor in the overall cost of development.
