I am trying to integrate the code described in the application note SPRA661A ("implementing a Software UART on the TMS320C54x with te McBSP and DMA") with a DSP/BIOS application. I would like to know if anybody has done it or can give me some references.

Hi everybody, i'm using 54CST on Sprectrum board. My application run with DSP/BIOS at 118Mhz. I've include Flash utilities for save audio message in flash memorie, but even with 14 wait cycles i can't write in flash. Manualy, with my

hello every one i am using C54CST Chip along with AIC20 Codec i have the follwing problem if any one can help me In a multi threaded DSP/BIOS application when i initialize AIC20 the system crashes/hangs and no further processing is done PLZ if some one can help me whether it is memory problem or anything else Thanks

Hi, I read in TMS320C54x Optimizing C Compiler SPRU103C, page 6-4, "6.1.3 Allocating .const to Program Memory". Its possible also to DSP/BIOS users ? How can I modify the boot.asm, rts.src ?

Hi everyone, I am working on DSK5416 and CCS. I'm doing real-time using DMA and McBSP to communicate with the codec. I'm working with 16 bits words and with DSP/BIOS configuration. I would like to know if the problem that I have is coming from data alignment. After interruption (full buffer: 1024 words of 16 bits) I use the following function: Interrupt function(){ int i=0,maxisync,maxica...

I am using the PEP5416 with code composer v3.1, and am having problems with memory allocation. In my code, I use the malloc() command multiple times, though after awhile, the program starts to return null pointers, indicating that I cannot allocate any more memory. The problem I'm having is that I have no idea where this memory is being allocated. I've been making changes using DSP/BIOS and...

Hi, I'm trying to get my project to link with the new linker and recipe file. I'm using the 5402 DSK and chose the DSK_ovly0 as the template. The problem is that the linker doesn't find any of the DSP/BIOS symbols such as BIOS_reset. The message it outputs is: "ERRO

Hi, has anybody already used the DAX API described in DSP/BIOS-II successfully? If yes, coud you summerize your experiences? We must decide very fast whether DAX will be used in our design or not. Cheers Gabor Kruchio
