Hi Group, I'm facing the following oddity: I'm working on a 65L Rev. 0.3. The aim is to download overlay code from 32bit SDRAM into internal 48bit PM via external port 1 DMA. In the simulator, this works like a charm. However, on the target hardware, the last two instruction words are not written into the internal memory (but they are present in

Hi all, I'm doing a face detection project on BF533. I use the EZ-Lite as the platform. First, the camera capture images, then stores in the SDRAM, then using the face detection algorithm to detect faces, and at last, send to LCD to display the final result. The problem is that the face detection algorithm is original designed for running on PC, now I have eliminated all the denpendecies...
