I am trying to start to use the DSP/BIOS for my application. I have a non-BIOS application that loads fine on the target with my custom .cmd file. But when I try to write a very simple program using DSP/BIOS, I see the following error when I try to "Load Program" Data Verification failed at address 0xFF80 Please verify target memory and memory map. I have looked at the .cmd file and the me...

hi everyone, i have some problems when i use dsp/bios. i want to use a software interrupt to contrule a task, when something have met, software send a interrupt signal and boot task. the task need to be booted peridicly. the problem is that how can i do this through bios. thanks!

Can anybody direct me to a ready to use serial driver for F2812s integrated with the DSP/BIOS? Last time I checked TI's web site they provided only one application note for a different, older processor. Thanks, Roberto Waltman [ Please reply to the group, return address is invalid ]

Hi All I have a DSK6416 board and I have an application including two SWI and one HWI, after running the main function and passing the control of algorithm to the DSP/BIOS, after some time , it gets back to the main function and I don't understand why? I have checked for stack overflow and it doesn't seem to be the problem . I appreciate any idea. Regards , Hamid

OK, this may be a stupid question but I'm going to go ahead and ask it. I seem to be missing something very basic in the use of semaphores. The SEM module in DSP/BIOS maintains a non-negative count of the number of times it has been "posted". Then when a pend occurs, the process either a) blocks if count = 0, or b) decrements count and resumes. I have one task T1 that must run to completi...

Hi All, I m working on DM642 DSP from TI . I would like to know as to how can i calculate the "time taken by a particular task/function". The CCS ver2.21 has the profiler in that,but,it takes hell lot of time(when using profiler,the CCS goes into Simulator MODE). Is there any other way around?. I have tried using DSP/BIOS object STS ,as specified in DSP/BIOS debugging tutorial.this particu...

Hello, i looking for user who have already use the "TMS320C6713 DSP Starter Kit". I am trying to estimate this developpement tool. Does anyone have trouble using the latest version of DSP/BIOS on 6713 ? Is it a robust tool ? Is DSP/BIOS source code available (in order to be able to correct some problem) ? I also want to have feedback about the C++ Code composer studio compiler. Is thi...

Hello, I am starting with a C54CST, I get the corresponding evalutation board C54CST EVM wihtout JTAG. I have some example given by SPIRIT the company which produced the algorithms included inside the DSP. I manage to use the flex examples applications using only a thread. However I can't used those with BIOS included. It starts the emulation via JTAG. When I load the program by UART, It ...

I'm trying to get three dynamically-created (versus creating statically under the Tconf gui) tasks running but the tasks just won't run. They are successfully created (TSK_create() returns non-null) but never run according to the event log. This is taken from the tsk example under the bios directory. Any ideas/help would be appreciated. --Randy *************** .tcf file: var mem_e...

Hi, I am trying a simple video loop through application using the EVM DM642 from Spectrum Digital. (EVM v3 with TI decoders, CCS 3.1, DSP/BIOS 5.2) As far as I can tell my code as well as the DSP/BIOS configuration is identical to the samples provided. Unfortunately, the program hangs during the start up phase, either during EVM_init() or in the capture task during the first call to FVI...

hi 2 all I am an engineering student frm india.I have to implement image processing algorithms in DSP/BIOS.For that i have to transfer the image into the SDRAM of DSk6711. I have actually implemented a C++ code in CCS. what is the size of int and char of C++ when implemented in CCS. plz tell the size(in bits )of one memory location of dsk6711.

Hello friends, I am tiring to base my application on DSP/BIOS. Unfortunately it seems to me that this OS puts big performance overhead (more than 20%). In the literature I couldn't manage to find a clear statement about the period of invocation of the task scheduler. For my case it seems that this period is about 80us. Can I control this parameter of the OS? Any help will be highly...

I'm trying to debug a video decoder device driver on a DM642 system that uses TI's class/IOM driver model under BIOS and in which the class driver is GIO. When the application first starts a video capture, it calls GIO_submit() to obtain a buffer of data, but the function call isn't returning, i.e., it appears to block. The problem is, according to the documentation, the function should ru...

In order to config on board codecs using IIC moudle (support by CSL API) in a DSP/BIOS program, I add a IIC write sentence behind video mini driver's configuration for a simple test like this: FVID_control(disChan, VPORT_CMD_EDC_BASE + EDC_CONFIG, (Ptr)&EVMDM642_vDisParamsSAA7105); addrI2C = 0x88 > > 1; for(i =0; i

I am working with a TI C6727 DSP, CCS v3.1 and BIOS v5.2. I try to allocate Memory with the help of MEM_alloc during running time. In the BIOS API manual TI wrote the function needs a Segment ID (segid). But what is the correct SegID of a memory section? My functioncall looks like this: void* p_ret; p_ret = MEM_alloc(IRAM,512,1); IRAM is a memorysection which I a had configured in t...
