RM57L843: rm57l843 EMIF Address

also note that I use address 0x68000030 in memory map to send 0x0030 address on EMIF address lines.also I am using HALCoGEN and CCS for programing.

Address line arrangement is given blew.
BA1, A0, A1, ............, A14

also FPGA memory is configure as 16 bit.
Please reply asap.

Regard

also I am not able to access some of addresses, i.e.
68000000 is accessible
68000001 is not accessible
68000002 is not accessible
68000003 is not accessible
68000004 is accessible
68000005 is not accessible
68000006 is not accessible
68000007 is not accessible
68000008 is accessible
68000009 is not accessible
6800000A is not accessible
and so on
its means that addresses with increment of 4 are accessible and others are not. Why?

Regards

also tell me about maximum allowable memory size which can be interfaced with RM57L843 CS3. 16MB or 64MB?

Hello Zain,

EMIF_nDQM signals operate as byte enables, these two signals should be connected to memory BE[1:0].

The actual maximum size for asyn memory is 16MB

Hello Wang
you said, actual size of memory is 16MB (you mean 16MBx16bits)?
also , I got right shifted addresses on EMIF address lines. Can you please tell me why this is happening?
