I am not sure regarding the interface of nios-sram output and actual pins of the sram i get the following from nios-sram address[15..0] be_n[1..0] data[15..0] read_n write_n select_n i am connecting them to the following on sram (CY7C09289) address[15..0] - address[15..0] be_n[0] - lb_n be_n[1] - ub_n data[15..0] - data[15..0] read_n - oe_n write_n - r/w_n select_n - ce0_n NOT(select_n) - ce1 i am not sure how to connect the CNTEN_N, CNTRST_N, ADS_N signals !! based on the datasheet i am connecting them as (Address load to address register) CNTEN_N - XX (Dont care) CNTRST_N - HIGH ADS_N - LOW I compile the quartus and flash the quartus code in JTAG, its fine When i try to run NIOS HARDWARE, I am still getting the error i have mentioned earlier - "Downloading ELF process failed" - the address location points to the SRAM ! Please help at the earliest !!!! Thanks in advance I have attached the Cypress SRAM datasheet - i am using one port of the SRAM only
