Hello Everybody, I have some quesitons regarding 'ti/examples/dsk6711/bios/audio' Example 1-On page# 6 of SPRA598: An Audio Example Using DSP/BIOS, It is written that "As the audio function will just read a frame from DSS_rxPipe and copy it to a frame in DSS_txPipe. The transmit rate will be the same as the receive rate: 48 kHz

Hi, I'm using a TMS320C6711 DSP with a PCM3003 Audio Daughter card. Can anybody explain me how to configure the DSP/BIOS (for RTDX usage) on a program that uses hardware interrupts (like 'loop_intr_pcm' by R. Chassaing)? This is what I am doing (please correct):

Hi, I have a clue about what may be wrong. I suppose the problem is that the SDRAM is not stable at the time when the second level bootloader transfers the data from the FLASH to the SDRAM. All the necessary settings are properly done, but there are some minor errors sometimes. After a detailed analysis over the working NON/BIOS bootloader I have identified the line after which the RAM becomes...

Hi, I'm trying to profile my code with bios, since the profiler seems to be heavely bugged. So I tried to use LOG_printf(&Debug, "time = %d", CLK_gethtime()); in various places in my code, but the problem is that CLK_gethtime returns always the same v

Hi all, can anybody suggest how to implement SWI without DSP/BIOS on c6711. I did't find any interrupt vector location to map a SWI. I implemented this way, I mapped interrupt selector value 10 ( No default event mapping for this one, given as reserved) to

Hello, Does anyone know how hardware interrupts and the DSP/BIOS interact? Specifically, I would like to find out what happens before and after the Main function is called, when the interrupts are really enabled and how interrupts can be selectively enabled. (I think the DSP/B

Hi all, Using the DSP/BIOS operatinf system, I have hard times with the memory allocations. I want to use 'MEM_alloc' / 'MEM_free' instead of using 'new' and 'delete' (I work on C++). The reson is : using MEM_alloc I can define the memory section to be allocated in. The problem is that in order to use MEM_Free, I need to know the size to free, and this is too mu

Hi, I have just started an application using DSP/BIOS, targetting a C6701EVM. I am toggling the LED on the EVM to give me an execution time for a section of code. I was wondering if enabling the cache would speed this code up. I placed CACHE_ENABLE() in my main(),

Hi all, I m using TI C6xxx simulator.In a program using DSP/BIOS i want to read from a file to do some processing and write in another file.I have read the DSP/BIOS user guide but couldn't find the answer. Pls give me some pointers to this problem. Thanks in advance

Hello everybody, I have a doubt about stack in DSP/BIOS tasks. In fact I'm currently using a DM642 based platform and I have these doubts: 1) the stack size of task seems to be limited to about 32 KB. Is this correct? Why is used this threshold? 2) how is allocated the stack? It seems that there is some hole in stack, but I don't know which alignment strategies are adopted by the DSP/BIO...

Hi. First time poster. :-) I'm doing a C6713 project using the MCASP. My MCBSP and HPI are going to be disabled so as to use the MCASP unit. This is how I plan to get the audio into the chip. So, in the DSP/BIOS config thingy in CCS, I see a ob

Has anyone an example code using C6711's McBSP with EDMA under DSP/BIOS II? Specially I am interested in the initialization sequence. I have written a test program which initializes McBSP in Digital Loopback mode and EDMA to feet the transmiter and read the receiver. It works f

Hi all, I am uncertain of the HWI and SWI interrupt configuration under DSP/BIOS. Though there is a sample code on the timer interrupt, I would like to find out more on how I can configure the external interrupt(int4-7). Anyone has written any code for it? Or, an

Hi all, I'm new to the C6711DSK and have a question regarding DSP/BIOS data types. I'm outputting a 100Hz sin wave from my 88.2kHz DAC. To produce this signal, I've filled a buffer of size 882, as follows - Float sig[100]; Void main() { Int i;

HI, For DSP/BIOS application, before main() function, all BIOS modules have been initilised. Main function is usually used for you own application initialisation (e.g. your own hardware initilisation). Also, in main function, global interrupt enable should not be allowed. So, You may try to interrupt when running in a task object. Hope this works. Regards, C. Yang _________...
