Nios & external RAM

Hi,

Is there a chance to use 32bit Nios with 16 bit external SRAM? When I add 16bit RAM in SOPC, I got upper and lower words written with the same value. For example:

Nios32_ram16bit.A

+m40000 #00040000: 35C0 35C0 6C40 6C40 3000 3000 736F 736F #00040010: 3301 3301 0038 0038 0038 0038 7FDF 7FDF #00040020: 7817 7817 9801 9801 9800 9800 9853 9853 #00040030: 9800 9800 7FF2 7FF2 3208 3208 0430 0430

Have you got any ideas how to do it? BTW: Device is EP1C6

Ehhh... It was completely my fault. I forgot that RAM pin A0 is connected to A1/A17 _not_ to A1 (on Nios EP20K200 board).

Now everything is working perfectly :-)
