Flash erase/write by copying function in RAM

Hello,

For one of application, I need to put default factory data in flash of the product. The product uses MB9AF112MA( Fujitsu MPU)and Keil IDE.

I copied the function to IRAM1( confirmed same by program counter address). Then followed the sequence for automatic sector erase algorithm. This includes writing predefined bytes to predefined locations in sector to be erased.

Similarly the algorithm is executed for writing the flash( from RAM).

I am not able to see any byte being written.

WHat may be the cause....plz help.

T n R,
