DE2带的IP核ISP12362报错问题解决 Error:avalon_slave_1_irq: associatedAddressablePoint out of range
问题来源与对友晶提供的ISP1362 IP核的使用,由于Quartus II版本问题,它提供的IP基于7.0版本,而我用的版本为11.1,在SOPC Builder中重新加载IP,就出现了上述的错误报告,在网上找了资料,以一下方法解决:
将avalon_slave_1_irq 的Inteface类型设置为interrupt_sender,Signal Type设置为irq_n,后续中断设置为对将avalon_slave_0,IP编辑过程是没错误了,但是添加的时候会出现将avalon_slave_0不能同时存在两个中断的问题,坑人的解决方法在此表示失效了。
然后就发散思维,自己添加了一个avalon_slave_1 Inteface,IP编辑和添加都没错误,只是警告这个总线没有信号相连,忽略,然后generate,麻烦来了,SOPC生成报错,生成过程被迫中止。
继续发散,将两个中断在HDL代码中合并,然后全世界都安静了,可是不要小瞧错误的隐藏能力,在Nios II编程过后,给你一个大大的耳光——“无法识别的硬件设备”。郁闷的结果!
没办法,去GOOGLE找大牛吧,在ALTERA官网,有人说用如下文件代替原来的isp1362_if.v
module ISP1362_CTRL (//Avalon Interface clk, address, readdata, writedata, writedata_avalon_slave_1, chipselect_n, read_n, write_n, reset_n, write_n_avalon_slave_1, irq_n, irq_n_avalon_slave_1, //Phillips USB controller OTG_ADDR, OTG_DATA, OTG_CS_N, OTG_RD_N, OTG_WR_N, OTG_RST_N, OTG_INT0, OTG_INT1, OTG_FSPEED, OTG_LSPEED, OTG_DACK0_N, OTG_DACK1_N); //Avalon Interface input clk, chipselect_n, read_n, write_n, reset_n, write_n_avalon_slave_1; input [1:0] address; input [15:0] writedata; input [7:0] writedata_avalon_slave_1; output [15:0] readdata; output irq_n, irq_n_avalon_slave_1; //Phillips USB controller output [1:0] OTG_ADDR; inout [15:0] OTG_DATA; output OTG_CS_N, OTG_RD_N, OTG_WR_N, OTG_RST_N; input OTG_INT0, OTG_INT1; output OTG_FSPEED, OTG_LSPEED, OTG_DACK0_N, OTG_DACK1_N; //Registers reg [15:0] data, readdata; reg [1:0] OTG_ADDR; reg OTG_CS_N, OTG_RD_N, OTG_WR_N; reg irq_n, irq_n_avalon_slave_1; //Assignments assign OTG_RST_N = reset_n; assign OTG_DATA = OTG_WR_N ? 16'hZZZZ : data; assign OTG_DACK0_N = 1'b1, OTG_DACK1_N = 1'b1; assign OTG_FSPEED = 0, OTG_LSPEED = 0; //Reset condition always @ (posedge clk or negedge reset_n) begin if (reset_n==0) begin data <= 0; readdata <= 0; OTG_ADDR <= 0; OTG_CS_N <= 1; OTG_RD_N <= 1; OTG_WR_N <= 1; irq_n <= 1; irq_n_avalon_slave_1 <= 1; end else begin data <= writedata; readdata <= OTG_DATA; OTG_ADDR <= address; OTG_CS_N <= chipselect_n; OTG_RD_N <= read_n; OTG_WR_N <= write_n; irq_n <= OTG_INT0; irq_n_avalon_slave_1 <= OTG_INT1; end end endmodule
后面的过程愉快而轻松,换过的方法非常多,郁闷到死,找资料还是GOOGLE靠谱。
