外设fpga做的8k的memory,用arm9去读写它,在linux2.6系统下;这样做对吗? 实际地址映射到虚拟内存中,用得到的虚拟地址去读写。 地址总线:a1-a14 数据总线:d0-d15 #define FPGA_BASE_ADDR (0x18000000)//片选为nGCS3 #define BWSCON (0x48000000) #define BANKCON3 (0x48000010) #define IP_SIZE (0x1FFF)//13根地址线8K的物理空间 static void *bwscon,*bankcon3,*fpga_base_addr; bwscon = ioremap_nocache(BWSCON,0x0000004); bankcon3 = ioremap_nocache(BANKCON3,0x0000004); fpga_base_addr = ioremap_nocache(FPGA_BASE_ADDR,IP_SIZE); writel(readl(bwscon)|0xD000,bwscon); writel(0x7FFC,bankcon3); for(i=0;i
