You need to have On-chip flash intel FPGA IP in your design. refer below link:
To erase the sector, you need to disable the write protected mode and erase sector.
For example, if you want to erase sector ID 5:
(bit offset 22-20 set to 3'b101..... bit offset 27 set to 1'b0)
I hope this will help.
Hello Shafiq. Thanks for your reply. Actually I wanted to do page erase.
From the userguide metioned 4 pages per sector. Let say i want to erase 1st page of
sector ID 1. Each page have 64Kb of flash memory.
To erase the 1st page , i need to disable the write protected mode and erase sector for sector ID 1 .
(bit offset 22-20 set to 3'b001..... bit offset 23 set to 1'b0).
( 19-0 page erase address (Corresponding address 00000-0FFFF) to select 1st page erase.
Is that correct ?
Let say I'm using your memory map address.
1. You need to disable the Write protection
- page 2 is within Sector 1. Thus:
bit 23= 1’b0
2. The address for Page 2 is between 10000-1FFFF.
- The IP core erases the corresponding page of the given address. Which mean any address you use within range 10000-1FFFF, the IP will erase the Page 2.
You can use any of this to erase Page 2:
You can give it try. And let me know the details.
