Hello All,
Working on a project with CW 10.4 and a DSC 56F8335 processor. I have the latest USB Tap (black plastic box) and my Target PCB is complete and works fine. On the legacy CW (8.3) I know you need to select 56F834x.cfg in order for the USB Tap to debug an 8335.
I have decided my old Win XP laptop needs to be retired so I started my new project on my newer Win 7 laptop and CW 10.4. I have noticed that in 10.4 on the Debug Configuration there is a drop down choice for the 8335 (see picture above).
When I choose this option I the project will not load and I get "Failed to resume target process., CCSProtocolPlugin : CCS: Core not responding" However If I select 56F8345 the project loads fine and runs.
The issue I am having is a subtle one and I am not sure if it is a debug config or something different about the Eclipse version of the compiler or just my code. This project works fine on the legacy CW and it runs as expected. I tried to import from the Legacy to Eclipse but that did not work so well so I recreated the project from scratch (I have done this to many projects with success).
I use strncmp() to match some incoming ASCII data and the issue I am having is this function is not working. I halt my project at the function and I see the data string I received and the one I am going to compare with all match but the strncmp() returns a non-match. When I step into the function I see that the data being passed as expected in str1 & str2 but when it is assigned to p1 & p2 - p2 becomes NULL.
//My usage of strncmp()
if(!strncmp(( char*)cmd, "HELO", 4))
//This is the actual strncmp() function I stepped into
int strncmp(const char * str1, const char * str2, size_t n)
#if !defined(__POWERPC__)
const unsigned char * p1 = (unsigned char *) str1;
const unsigned char * p2 = (unsigned char *) str2; Here is p2 becomes NULL
unsigned char c1, c2;
while (--n)
if ((c1 = *p1++) != (c2 = *p2++))
return(c1 - c2);
else if (!c1)
break;
#else
const unsigned char * p1 = (unsigned char *) str1 - 1;
const unsigned char * p2 = (unsigned char *) str2 - 1;
unsigned long c1, c2;
while (--n)
if ((c1 = *++p1) != (c2 = *++p2))
return(c1 - c2);
else if (!c1)
break;
#endif
return(0);
What I am wondering is this an issue of an incorrect debug profile or should I look at some other configuration setting?
Thanks,
Dave
