TMS320F28075: Problem in interfacing SRAM (M5M5W816TP) with TMS320F28075

Part Number: TMS320F28075
Other Parts Discussed in Thread: TMS320F2812,

Hi, I am currently migrating an application from TMS320F2812 micrcontroller to TMS320F28028075 micrcontroller.

I have interfaced SRAM M5M5W816TP with TMS320F28075 using External memory interface.

I am facing issue in reading and writing to SRAM.

Code flow

SRAM_write 0xA1C1  (at location 0x100020)

SRAM_write 0x5020  (at location 0x100040)

Read SRAM location(0x100020) =  0x5020 (expected 0xA1C1)

Read SRAM location(0x100050) =  0x5020
