Tool/software:
Currently I am interfacing the external flash device to the tms570lc4357 microcontroller through an EMIF interface,we followed this process for writing and reading the data to and from the external flash device.Firstly we are erasing the specific sectors after that we are trying to write the data in it after that we are reading the data.while erasing the external flash we are sending the commands but the commands are not stored in flash locations,busy signal and control signals like WE and OE is also not coming,But flash locations have this data 0x0000FFFF,we couldn't understand whether the sector erasing is completed or not whenever we are trying to write data after sector erasing and reading back the data we are getting FFFF.Anyone suggest me why this is happening what is the solution for it.
