Mr.Russell,

Yes..I did ensure that no other resources are accessing the flash at the time I write.

I actually made a thin test routine, a main function which calls various driver functions in the flash driver c file.

The whole thing runs on top of an RTOS-Nucleus.

And since I have a debugger, I can actually see the addresses and data I write going into the memory mapped area of my processor memory. They are all right.

I can read CFI queries, Manufacture id and device id from flash. This proves that the existing addressing is correct. So I dont think I need to shift the addresses by a bit to the left.

I guess I need to focus the hardware settings and board level settings as well.

If you get any light on the thing, please do let me know.

Achu
