NIOS II 9.0 BUG

来源:百度文库 编辑:神马文学网 时间:2024/06/30 20:04:20
问题现象:

在ep2c下试验过没有任何问题的NIOS II在ep3c中无法自举(启动),但是看上去附加的verilog IP core

在工作,只是nios2的C主程序无法运行。nios2eds也没有什么明显的报错。

原因:

NIOS2_EDS_9.0 的Flash Programmer有bug!
解决方法是把/opt/altera8.1/nios2eds/bin/sof2flash.jar 复制到9.0的相应目录里。

Problem

Why does my Cyclone III Nios II system not boot up from an EPCS device when I program the EPCS with Flash Programmer ver.9.0?

Solution

Nios® II embedded processor executable code is not correctlyprogrammed on an EPCS device with version 9.0 and 9.0sp1 Nios II FlashProgrammer tool chain.

Version 9.0 and 9.0sp1 contain a bug in the tool chain. To solve this problem, contact Altera® technical support via mySupport to request the Nios II EDS 1.01 patch.

This problem will be fixed by Nios II EDS version 9.0sp2 .
