Hi,
I am using Nios II Embedded evaluation Kit (Cyclone III) (EP3C25F324C6).. My Intension is to read and write data to /from the SSRAM on the board ... in byte manner Now I have to use SRAM_D0-SRAM_D1 pins to configure the device (SSRAM) to read the data from the SSRAM... So ,I changed in the device settings (User IO).. to use those pins as user IO . But even then I am unable to get the last byte value correctly.. So, Please suggest me how to use those pins correctly ... Please help me out of this issue .. Waiting for a reply .. Thanks, Srinath.Link Copied

Did you understand the cotrol timing requirements of SSRAM from the datasheet?

Check whether Byte enables are playing any role in your code. Also, when you say last byte, Do u mean last byte of data that is written to SRAM? What Size{in Bytes} of data have you tried writing to SRAM?
I really wonder whether last byte is written properly or not!!:mad: To confirm.Try this out: Write data in multiple bursts linearly and read linearly to observe whether the last byte of every burst is missed out/ not!
