     I used a imx6sx-sdb custom board,want to use M4 to access fpga by eim,when I read or wrote(using address range 0x04000000~0x07FFFFF) ,no matter what address I gave, the address collected by FPGA was always 0.but the cs、rw、oe signals were right,and the data on the data bus was also correct.Can anyone knows what is the problem?
