Hi .

I'm using max10 FPGA in user flash memory in my project . It has 4 pages in one sector each page is 64kbits of size. Now how to identify what is starting and ending address of each page in memory to write or read data from flash memory.

Hi,


You will need to calculate the starting address and ending address of each page based on the starting address of that sector.

Hi,


Each address will contain 32bit data. So the end address should be 0x800.

so you did 65536/32 = 0x800 right?

Hi,


Yes. If you using Qsys with Nios then it will be using 8bit addressing. So you need to divide by 8 only which will be 0x2000.

This is my configuration sir.

Each address is storing 32 bit data.

The picture you are showing will be based on 8bit addressing. So I would recommend you to divide by 8.
