hai friends, i am getting a new error which is not familier for me, that is memory map prevented read of target memory specified this cause program to stuck in some places where user defiend variable is accesed why its happening i guess it is something with , stack or heap , or something with .cmd file please help me in solving the problem -- regards, Joshy m....

Hello, I am in the process of determining if our Unix based (QNX) RTOS application can be migrated over to the DSP platform. My major concern is if we will have high level support that we currently use in our C code. Will the DSP RT Kernal provided by TI, support: POSIX / ANSI compliance? Is there a high level ethernet stack driver, that allows function calls that will not require d...

I am looking for most efficient sorting algorithm tailored for c64x (if not, for any dsp). My requirements and assumptions are 1. Number of elements for searching (Min, Max)= (2, 4300) 2. Data type is integer. 3. max. stack size = 4KB (if used by recursive sortings). qosrt is available in rts.src and rts64plus.lib. I have checked the qsort.c in rts.src and observed it is not optimized. U...

C6455 DSK CCS 3.2 Hi all My project has been working and compiling well for some time now, but recently I've experienced some trouble with CCS. After about every 5 'Projects Builds' I receive the following error Unexpected Fatal Error encountered which may have been caused by a stack overflow,out of memory condition or access violation and CCS crashes. I do have quite a large a...

Hi, I'm using NMI as power fail interrupt, to save important vars. Sometimes this didn't work. After a lot of debugging I found out why - the SP is sometimes corrupt! More debugging lead me to a linear assembly routine which is translated into code that uses the SP. IRP is saved to stack and SP is saved to IRP. As long as this code isn't interrupted all works fine. During normal op...

Desr sll, I am a final year project and i am working on the interaction of DSK91C111. I recently bought DSK91C111 ethernet daughter card but without any license as i got suggestion from someone that i can use the ip stack from NDK's trial version and so i will be able to integrate it with the DSK TMS3206713. Now i tried to run a demo program from Matlab which has DSK91C111 in it (acoustic nois...

Hi, is there a document that states the use of registers when calling a assembler function from C. I know that B3 is the return address; B15 is SP; A4, B4, A6, B6, ... are the arguments. I checked the assembler code of a lib function. There was B10 saved to the stack. I wonder what is located in B10, and if there are other registers I must preserve. TIA Gustl _______________...

Hi all! I'm constructing a C6xxx-based circuit for which low-cost is the top priority. (still debating between the $9.66 C6204 and the $20 C6410 for the DSP...) Looking into my stack of Spectrum Digital reference designs, TI DSPs are typically booted up with fancy power sequencing chips... (Which, by uncanny coincidence, usua

Hi c6x,I have a problem. In my thesis there's a function that operate on matrices, so I created two different version of this part of my code; In the first version (OLD) I've implemented independently my code, and in the second version (NEW) I use the dsplib library of C6701. T
