Hi nwee0,
You need to have On-chip flash intel FPGA IP in your design. refer below link:
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/ug_m10_ufm.pdf
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:
0xF7DFFFFF
(bit offset 22-20 set to 3'b101..... bit offset 27 set to 1'b0)
I hope this will help.
Thanks
nwee0Hello 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 .
Example:
0xFF100000
(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 ?

Hello Shafiq. I draw simple memory map address of pages to sector for max10 onchip flash (attached files jpg). And If I want to erase 2nd page for sector ID 1 , we write to csr 0xFE210000 ?
Regards.
