GPMC with 15-bit Adress and 8-bit Data lines for SRAM HY2256ALP

Dear Sir,

I am using GPMC from beaglebone black by using Memory Mapping technique. Whenever i am configuring for 8-bit Non-Mux device. i am getting the correct output.

But i want to access 8-bit data for 15-bit address, for that i am configuring as 16-bit Non-Mux device. 

If i try to access the offset address 0x0001. i am getting output at GPMC_A1 instead of GPMC_A0. I think this is happening because the device i have configured is 16-bit Non-Mux...

If i configure the device as 8-bit Non-Mux... I can access the address from GPMC_A0 to GPMC_A7 only.

 

I want access 15-bit Address (GPMC_A0 to GPMC_A14) and 8-bit data (GPMC_AD0 to GPMC_AD7)...

so please kindly give me the guidance to achieve that...

Thanks & Regards
