Hi all, We are developing a device driver for the 16C550CFN uart, present on the 5402 DSK. The driver is based on the streams IO model of DSP/BIOS.We are facing the following problem: When the SIO_get internally calls the DXX_issue function , t

hello all, I am trying to use RTDX to stream data from the host to the target, I am using the c5402 DSK, inside main, I call codec_open, but before calling it i must calle brd_init, which seems to mess with something already initialized by the DSP BIOS startup (pr

Hello all, I'm building an audio processing app, and would like to use DSP/BIOS for the i/o. I'm using CCS 1.2 with the '5402 DSK. Since I'm still new to this platform, I used the audio example in the bios subdirectory as a base for my host program. Trouble is tha

Hi all, what do you think on the following synchronisation problem: - two DSP/BIOS task objects (TSK_A and TSK_B) have the same priority (e.g. Priority 1) - TSK_A is running (its execution state: TSK_RUNNING) - TSK_B is ready (its execution state: TSK_READY) - interrupt o

Hi, My application is getting too big to fit in the near memory space. I am experiencing a few problems using the CCS 2 DSP/BIOS config tool. 1. It appears that the OVLY bit is optional for extended program memory, but when I select far mode (in the config tool), the co

From TI's Doc, it seems the RTDX might be used independently from the DSP/BIOS. Well, after I insert the RTDX related code(declarations, function calls, vecTable and rtdx.h, rtdx.lib), I got an error msg saying RTDX_write, RTDX_poll and ATRAP_H are undefined symbols. I thought they s

Hallo, I'm sure somebody has seen this behaviour before and could help me out. I've built a simple DSP/Bios project with just a main and a log object configured. This is for the DSK5402 starter kit. The problem is the program ends up at a symbol "abort"

Hi, I'm trying to get a DSP/Bios project going wiht the DSK5402. I've started getting this message: Data verification failed at 0xff80. Please verify target memory and memory map. Is this trying to tell me I have a problem with the memory on the DSK?

I've worked through the Application Report SPRA598: An Audio Example Using DSP/BIOS, on my DSK 5402. It's a simple program just copying the input to the output. But my output is just a weak copy of the input and a lot of noise (less noise when i change the JP3, but still too m

Hi, I am using a C5402 in my own prototype PCB which includes a 256KWord FLASH & 2 64KWord RAMS. The Flash and Data RAM can be swapped using an attached CPLD. I have developed the DSP/BIOS source code to the point where I can use hex500 to create a boot table

Dear All ! Does someone have an example (project) that performs transmitting digital data through McBsp0/McBsp1 (DSK 5416) (using DSP BIOs or NOT) ? It would be a real help for me. Thanks a Lot.

Could anybody explain to me why there is a memory hole for the 5402 DSK at 4000-8000? I don't understand why this is not external memory mapped to the FLASH or SRAM. Somehow, DSP/BIOS also knows that 4000-8000 is not valid memory and prevents me from configuring EDATA for 4000-

I have been receiving requests for ad50init.asm file, which initializes the AD50 codec on the C5402 DSK board using asm language, intended for very small footprint applications that do not use DSP/BIOS. The file was posted on the C54x group archive for almost 2 years bu
