SDRAM controller Timing parameters

Hello,

Could anyone help me to understand these parameters:

homeinit_0-1681305016911.png

I want to add my memory but I am struggling a little bit with the timing since the datasheet has not had the same naming.

I am using the H57V2562GTR-75C running at 133MHz.

Thank you  in advance

Hello, I managed to solve my issue, here are my values, it works for the moment, and the code is running from the SDRAM:

homeinit_0-1681383760967.png

[crt0.S] Inst & Data Cache Initialized.
[crt0.S] Setting up stack and global pointers.
[crt0.S] Clearing BSS 
[crt0.S] Calling alt_main.
[alt_main.c] Entering alt_main, calling alt_irq_init.
[alt_main.c] Done alt_irq_init, calling alt_os_init.
[alt_main.c] Done OS Init, calling alt_sem_create.
[alt_main.c] Calling alt_sys_init.
[alt_main.c] Done alt_sys_init.
[alt_main.c] Calling main.
Hello from Nios II!

I am running the code from the SDRAM and I wondering why I have [xxx] xxx messages before the program? if you have an idea/explanation I'll take it!

Thank you!

You may checkout this page on the parameters description.

Unfortunately, I am not familiar with the device H57V2562GTR-75C so I can't advice much on that.


Best Regards,
