Hi, all. I am using a 'c5410, to which I am trying to hook up an Intel 28f400b3 flash. This is the same flash that is used in TI's document SPRA585 (Connecting TMS320C54x DSP to Flash Memory). I am having a problem communicating with the flash. It is connected as it is in the document, and I am using the code provided in the document to erase/program. The code always jumps to the error loop when verifying if the erase was accomplished. When the status register is checked at this point I get 7f, which pretty much means that everything is wrong. This makes me unsure that I am getting the status register value when I attempt to read it. Does anyone have any experience interfacing to flash memory that could help me out? If anyone has used the code and/or hardware wiring described in SPRA585, I would appreciate hearing about any changes you had to make to get it to work properly. Thank you for your help, Leigh W.
