I'm programming in C++ on a 6713 DSP. I've told the compiler to use the -pe switch for embedded C++. I'm linking in the fastmath67x.lib file into my project, and have listed that library in the linker order before any of the other files without linker order. Am I doing what I need to take advantage of the fastmath library for things like the cos() and sin() functions in my code, or am I...

Hi, We are trying to run a prog on a self-developed C6701 DSP card. The problem is that the code never enters main(). We are using memory MAP 1. The linker command file and vectors_poll used is same as provided in Rulph Chassiang C6713 book. The linker command file is this : --------------------------------------------------------------------------- MEMORY { IVECS: org=0h, le...

Hi Mike, I made the test. No warning while compiling, I just get an error while building because there is no "main" (unsresolved _main).

Hi everyone, I am working on c64xx and using ccs 3.3. In the code, I need to use the malloc(), which means I need to define heap in memory. I tried to use the DSP/BIOS config or the linker options (Project-> Build Options-> Linker-> Basic-> Heap Size). The heap size is 0x10000. But when I check the .map file, I found, //.sysmem * 0 00011000 00000000 UNINITIALIZED My qu

Hi to all. I am a student and I am trying to learn using DSP with th eDSKBoard 6713. I have a problem when I declare an array ( buffer1 ) in SDRAM, i.e. in the section ? .my_section ?. What I have done is: #pragma DATA_SECTION(buffer1,".my_section") Int16 buffer1[500000]; Using DSP/BIOS, it creates a linker command file by default ( prova_6cfg.cmd ). To add

Hi, Ive just discovered that when I enable C++ (Treat C files as C++ Files (-fg)) copiler option to enable C++ code, the linker is unable to resolve symbols in main.c with their references in the DSP/BIOS *.cdb In other words when I enable -fg then the linker complains. Is anyone else combining C++ with DSP/BIOS? Many Thanks

Hi, I have a linker problem. I tried to find a sollution here, but I didn't find the right one. So the problem is that, I got the error message "error: relocation value truncated at 0x24 in section .bios". I am using --mem_model = far and RTS call = far, but it is not helping in this situation. Should this be handled somehow with -r argument? [audio_dspcfg_

Hello I am using the DSK6713 for Speech recognition application which performs Cepstrum feature Extraction and Hidden Markow Model for recognition.

I ran into a strange thing when compiling code for my DSP recently. I would like to know what is going on, if this is something I don't understand in a difference of C vs C++, or something really strange in the Code Composer Studio Compiler / Linker. My understanding was that a a char array was simply dealt with as a pointer to the chunk of memory that was declared. The following
