HELLO everyone,
I am trying to write and read into a Micron Flash Mem MT29F16B... using MSP430F2419 uC. initially i woudl like to write only 1 byte to the flash mem on a 400khz clock source...
i am following the routines given in the datasheet for cmd, addr, and data in/OUT:

however, when i read data from the Flash, i see only FFh at the input port of the uC. I checked the voltages on the Data lines of the Flash Mem, and they were reading 3.3V.

Can any one please suggest me what could be the problem in this??? any help would be greatly appreciated
 

Hi

Flash memory have special command to alow programming - you must use this command befor trying to write data into flash

All the best

Bobi
