FMC Clock Mux not found

[mids400]

Hello,

Im working on a Project, which i use with it STM32F750N8H6 with external Memory and im trying to interface them to each other.

I have so far now done the Configuation of GPIO, TimingParameters..etc but i wanted giving too the Value of the Clock Frequncy for SDRAM in Clock-Configuation, then i have not found the FMC-Clock Mux!

Where can i entering the Value in order to make the Interface well working?

Thanks,

Hello @mids400 

First let me thank you for posting.

Based on the RM0385 : The AHB clock (HCKL) is the reference clock for the FMC.

So in order to change the clock frequency you need to change the HCLK

Thx

Hello Ghofrane,

Well, i sew that and i have changed it to 200MHz that means now the value of FMC Clock 200MHz. Then i have configured the SDRam Duty 2 Cycle in order to get 100MHz as mentioned in the Datasheet of the Memory.

Its worked now very well.
