Hi, I am using TMS320VC33 in MCBL mode.But till now we haven't done any boot loader programs, as we are in the initial stages of programming.We are simply writing some code for adc, dac etc for testing purposes.Initially it was fine. But nowadays we find some kind of degradation in the performance of DSP in the sense that,after we run the program twice or thrice the dsp stops responding.hard...

Hi, I am new to this platform. I am using the tms320vc33. I am using code composer version.4.10.36 I have written an inialization code in (C and asm) for dsp. When I startup, the cpu registers are showing some default values and not zero. If I start to trace with these values, at the end of some function calls the trace goes to some unspecified location. But if I make the cpu regist...

Hi, I am using C31 processor , if i decalare "unsigned char" data or "unsigned short" , the code composer shows 32-bit assigned to it . Is it possible to decalare 8-bit or 16-bit data type for the C31.? Also if two memories one 8-bit wide and another 16-bit are externallay attached to the C31, and if i want to move 8-bit memory data into 16-bit memory data what would be the efficient way to...

I've been given this new board to bring up. I see two problems (maybe they're related). The board features external RAM mapped from address 0. The DSP is configured to run in Microprocessor mode for now during debugging and just load directly to RAM from the XDS510USB JTAG emulator. The connection to the board seems to be fine and I can manipulate values in RAM. 1. I cannot step....

Hello everyone, I am currently trying to debug a TMS320VC33 DSP target (my own design) board with the help of the XDS510PP (Plus) emulator and Code Composer (version 4.10.36). I have downloaded the relevant drivers from the Spectrum Digital website and have established communications between the XDS510PP emulator and the target board, i.e. I can load and step through code as expected. My pro...

hi, i'm a newbie with tms320vc33 dsk , and i would like to know : 1) is it possible for me to alternate between assembly language and C language within a same source code. if yes, how? 2) the software included ( im using version 2.02) has up to 20 application files (dsk3a, dsk3d, dsk3win, dsk3osc, to name a few). so far, i'm only using DSK3DW, which is stated as the debugger. what are the ot...
