Hi, I design a board including a TMS320VC5416 and an Am29LV160D (Delay 70ns) flash memory. I connect Data and Address buses of DSP to the flash directly and make control signals of flash with MSTRB#, and R/W# of DSP. I observe control signals, data and address buses of flash and all of them it seems are correct; However, I can?t write in a specific position since when I read the position I

Data and Address buses are inactive !

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#,...
