Part Number: AM3352

Hi,

CPU:am3352

OS:Vxworks7.0

AM3352 connect FPGA through GPMC. CSN0~CSN3 are all connected to FPGA. He used non Multiplexed Address Data 16- Bit Device mode. No matter how to set and modify code regarding to CSN0 when AM3352 execute write operation, there is no output signal, but it can read normally and CSN1/CSN2/CSN3  are all normal.
