All, hi I design a relatively simple board consisting of a TMS320VC5416, a Flash memory, and a FPGA. I use the Flash to place my code. To program the flash, I declare it external in data space (DROM = 0). I connect the data and address buses directly from DSP to the Flash memory. Further, I make OE, WE, and CE signals of the Flash using MSTRB#, DS# and R/W# signals of DSP. The MSTRB#,...
