Dear all, I have two questions. 1) Could anyone recommend a low-cost JTAG emulator for PC, that would be compatible with c6000 devices 2) Is it possible to program my DM642 evaluation board (the Spectrum Digital model) _without_ using a JTAG emulator? Thanks in advance.

Hi Folks, I had a strange experience this past week (well, maybe not so strange for TI...) in which I started a fresh copy of Code Composer Studio (I'm using 2.18, I think), so that there were no breakpoints or other debugging session setup, and then loaded and ran (via F5/Run) an executable into a TMS320DM642. Then during the processing of subsequent host processor messages (via the PCI b...

Hi New to all this DSP stuff but I'm programming the TI DM642 in C. Looking at some sample sourcecode for a similar task from someone who knows a lot about DSP, I've noticed that they've not used pointers or passed anything between procedures and relied on global variables. I'd always been taught global variables are the most sinful thing a coder can do but wondered if there was some reaso...

It suddenly happened that my DM642 board failed to run to the main(). While debugging, I found that c_int00 can't pass some assembly codes, which is to wait for the reset complete of VP1. I checked the register VP1_CTL, and found that VPRST field is 1, which means it can't finish the power on reset. but both VP0 and VP2 are OK, seeing their control registers. Does anyone know why?

Hi, Soon i will implement a video compression algorithm on DM642. I'd like to recover the compressed data, which will be stored in SDRAM, in order to be able to replay the video on the PC. Can you tell me if Code Composer allows us to recover data stored in external memory and to save them in a file on the PC ? Does RTDX allow to do that ? Could you point me to some example codes ? ...

After program the flash with these three parts and power-up the boa...
