CCS/TMS320F28377D: emif

Tool/software: Code Composer Studio

I would like to use 28377D to communicate with FPGA through EMIF (8 address lines, 16 data lines). The communication part in FPGA is controlled by the CS2 signal, EM1RNW, and EM1WE from 28377D. The 28377D is configured EMIF1 in 16bit ASYNC mode. I followed the Technical Reference Manual, EM1BA[1]--A[0], EM1A[7:1]--A[7:1]. And I have configured the GPIOMUX of these pins. However, when I try to read/write address 0x0010 0000 to 0x0010 0008, the CS2 signal still kept high level. Signaltap 2 indicated the wrong address on the address line. (Program in FPGA is used 'case' sentence, to put data on the data bus when received corresponding address information through address bus.)

Please help me and give me a hint on how to solve this problem.

Thank you!
