Re: Announcing New Book by Rulph Chassaing

Started by October 8, 2005

I recently bought Dr. Rulph Chassaing's new book "Digital signal processing and applications with the C6713 and C6416 DSK" and a C6713 DSK from spectrum digital. I have been trying to following the examples in the book, but run into one issue.

I was able to load and run sine8_LED.out from the CD successfully. I was also able to following example 1.1 and built sine8_LED.out successfully except with a few warnings (see below). But when I tried to run this executable on the target. It got stuck at somewhere. So I set a break point at the beginning of main() function of Sine8_LED.c file, reload and run the executable. The break point was hit. I stepped through the code and found out that it was stuck at DSK6713_init() within c6713_dsk_init() function.

Could someone provides some hints to resolve this issue ? Your help is very appreciated.
