Any updates on this error/issue ?? Kindly help in case if you are familiar
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
