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...

Hello, I wanted to find out a way to check CPU load using an API in my C code. I use CCS 3.1 and DM642 DSP. The CPU load graph is available but to find out the exact value(if possible) using an API is required.

When i use cpu filled a part of off chip SDRAM(bufferA) with some data, and then i use EDMA to transfer this data from bufferA to a part of on chip SRAM(bufferB), at last i use cpu to copy this data from bufferB to another part of off chip SDRAM(bufferC). The algorithm was like this, for(;;) { use cpu change ...
