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

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 .

 

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.

Hi nwee0,

 

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.

 

Example:

You can use any of this to erase Page 2:

·        FF710000

·        FF71FAB0

·        FF71FFFF

 

You can give it try. And let me know the details.

 

Cheers
