SDRAM controller Timing parameters - SDRAM controller Timing parameters Hello, Could anyone help me to understand these parameters: 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 Replies: Re: SDRAM controller Timing parameters I'm glad to hear that your question has been addressed.

[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!
