Hi, Im trying to convert an app that currently runs on a c5402 which has been built without DSP/BIOS to use DSP BIOS, however im having some difficulty translating some of the ISR's : Ive found HWI_INTx but i cannot find the following in the BIOS Config Editor:

Does anyone now if it is possible to use HPI as IO when DSP/BIOS is used? I've tried this without DSP/BIOS and it works but not with DSP/BIOS.

Hi groupmembers, We are developing basic analog phone on TI's TMS320C54CST.. We need multithreaded support so we are in the process to convert our existing single threaded application to DSP/BIOS env.. My Question is where I can find the sample example or documentation for DSP/BIOS as I dont know what are the consideration to develop application on DSP/BIOS environment.. If...

hello everyone, am using CCS1.2. After i have loaded a DSP/BIOS out file onto the DSK (5402) and i try to invoke some or any of the DSP/BIOS tools CCS completely shuts down. If i try to runthe program without any tools it seems to be running. What can the problem possibl

Hi, I'm trying to build a DSP/BIOS project. I include bios.a54 for the bios stuff. I understand this file as being a sort of library, but Code Composer trys to assemble it and gets stuck in a loop somewhere. Code Composer has it in the list of source files an

Hi, I am trying to change the DSP speed in the DSP/BIOS config tool to 40MHz from 100MHz. When I save the change, it writes its config files, then when compiling it brings up errors about the syntax of the .s54 file which the DSP/BIOS config tool writes (improperly).

Is the DSP/BIOS used in general, or do people write their own kernel software/firmware? I know it depends on what the application is, but it seems like the DSP/BIOS is nice for development, but in production, it might make the kernel bigger than it should be and the more one takes ad

I am having trouble switching the C5402 DSK to mircocomputer mode using DSP/BIOS. The way I did it was by changing the MP/#MC bit of PMST register value within the DSP/BIOS cdb file. However, my program does not run correctly afterward. It ran okay before when I used microprocessor m

Just wondering what the group thought of DSP BIOS or any other RTOS. DSP BIOS seems powerful, but, perhaps it is just me, I have not found good documentation on how to use. How much agony is required to get this going? ucos is available and the port seems t

Dear Friends, I am learning about DSP/BIOS based DSP System Design. Now I tried to understand the structure of PLIO Adapter and LIO Controller. It seem be complex and luxury. Because my custom design without DSP/BIOS is very simple. I wanna to know the situ

Hi, As far as I know, there shouldn't be any trouble with making use of RTDX or DSP/BIOS capabilities on TMS320VC5402 connected via parallel port. Am I right? Need I JTAG ? I am racked by all these doubts since programs with RTDX or DSP/BIOS do not want to work. Thanks f

I need to boot my C5409 EVM board in HPI mode. I read the SPRA382 (for C5402 HPI boot) and SPRA672A (for C5409 boot). Now I can boot a simple blinking program like the SPRA382 example but when I try to boot a large aplication that use a DSP/BIOS the boot fail! I have move the

Brian, Thanks for your response.... I think I may have become one of those old engineers that I used to complain about when I was younger....but that configuation tool for DSP BIOS drives me nuts...So I am not even sure that you could bringing up something quicker

-Jeff "On C54xx devices, SPCR1[0] access requires a sub-address setting; i.e. SPCR1 register, port 0 (McBSP0). Therefore you have to set SPSA0 first (located at address 0x0038). Are you doing that before trying to read RRDY?" I open the McBsp0 using DSP/Bios Configuration. So I'm wondering, Is the SPSA0 set automatically when using DSP/Bios Configuration ?

Hi, What can be the cause of my problems with launching DSP/BIOS Tools ? I tried, for instance, to configure appropriate objects like SWI, HST according to what I needed. Since I carried out instructions recommended in the CCS Tutorial, I am convinced the trouble doesn't lie h

Hey all, I'm getting stuck somewhere in the GBL_init module of DSP/BIOS. I know I get past the part where it calls the USERINITFXN because I am able to turn off leds up until my function calls RET (it's an assembly function). However, when I put code in the BIOS_init function after it calls GBL_init, my code never gets called. Here is the code from GBL_init including where it calls my USERINITF...
