由于7.1下找不到做目标板,直接加入CFI,但是CPU中没有从Flash启动的选项.于是装了5.1,结果5.1用mk_target_board命令时出错,只好装5.0,做了目标板,引脚连接按电路板实际情况连,我的Flash是AM29LV800,OE接读,CE接CS,BYTE,RY/BY,RESET接高电平,19根地址线接地址1到19,0空着.数据线对应接.编译时,出来WARNING: Default charset GBK not supported, using ISO-8859-1 instead的警告,不知如何消除,于是打开Flash下载,结果如下: #! /bin/sh # # This file was automatically generated by the Nios II IDE Flash Programmer. # # It will be overwritten when the flash programmer options change. #

It is likely that you are using a flash-programming FPGA design which was not created for your target board.
In order to program flash, you must first create a purpose-built flash-programming design (i.e. FPGA configuration) and associate it with your particular board. The Nios development kit is delivered with purpose-bui lt flash-programming designs pre-built for several development boards. If you wi sh to program flash on your own board, you must first create a flash-programming design.
The process of creating a flash-programming design for your board is mostly automated. From a bash-shell, execute this script:
mk_target_board --help
The help-message includes references to other documentation on programming flash and targeting Nios systems to custom board designs. - exiting. WARNING: Default charset GBK not supported, using ISO-8859-1 instead
看这信息,把目标板的.sof文件已经下载到U10,也就是EPCS4,但是程序文件未能写到Flash,检查了硬件连接供电正常,管脚连接定义也没问题,不知这是什么原因?请大家指导 It is likely that you are using a flash-programming FPGA design which was not created for your target board. 这段意为不能为未建立目标板的项目上进行flash下载,但我确实时建立并生成了,而且在做测试时,能找到这个目标板选项并选择了这个目标板 作者: kzw 时间: 2007-11-29 11:09
