    Hi, Junbum


    You can find the start and end address of CFM1 (for your application image) in the .map file when you generate the .pof.


    You need to copy and paste the block with above start and end address into a new .rpd (for the application image to be updated remotely). But in newer Quartus versions, you don't have to do that, there is a .rpd automatically generated for CFM1.


    You need to create a quartus.ini in your project directory, and put below line in it, before you do covert programming file to .pof from your application .hex.

Hi, Junbum


I find there is no interval timer in the AN741 reference design.

May I know where the interval timer coming from ?

That's what I added because I needed it. In the application I want to use, I added the Interval Timer along with SPI, UART, and GPIO, so they all worked normally. And when I tried to add RSU function to my design, a problem occurred in Interval Timer.
