Linux与AlteraDE2-115

Question

根据使用说明，我试图在我的AlteraDE2-115FPGA上运行Linux。显然，第一部分起作用了：

$ quartus_pgm -m jtag -c USB-Blaster[2-2] -o "p;tPad_Selector.sof"

然后我会遇到一些我不明白的问题：

$ nios2-flash-programmer --epcs --base=0x0a001800 tPad_Selector.flash
Using cable "USB-Blaster [2-2]", device 1, instance 0x00
Resetting and pausing target processor: 
OK
No EPCS layout data - looking for section [EPCS-010216]
Unable to use EPCS device
Leaving target processor paused

我在Altera论坛上找了一遍，都听不懂。我该怎么做？

我已经格式化了SD卡的三个分区: ext3，fat和交换。也许SD卡不兼容，或者它可能是什么？

调试输出：

Answer 1

您的指示(不是针对DE2-115，而是针对另一个板)为您得到的错误提供了指示：

没有EPCS布局数据-寻找EPCS-010216节.

DE2-115...

注意:当您执行‘nios2-flash-程序员’命令时，您可能会得到一个错误，比如没有EPCS布局数据-寻找EPCS-010216节。在这种情况下，请参考Altera论坛页面的‘nios2-flash-程序员’或章节“非标准闪存记忆”的"Nios II Flash程序员用户指南“，在第23页。

你查过"Nios闪存程序员用户指南“programmer.pdf部件A.非标准闪存吗？

要使用本节中的过程，您需要使用闪存设备的数据表。确保您完全了解该设备的CFI方面。一些CFI闪存设备包含丢失或不正确的CFI表信息。在这种情况下，基于CFI表中的错误信息，Nios II Flash程序员可能会失败。对于这些设备，Nios II Flash程序员提供了以下方法来覆盖CFI表并成功地编程闪存.在尝试创建覆盖文件之前，始终尝试使用内置识别和覆盖。要确定flash程序员是否识别设备，使用选项从命令行运行闪存程序员。如果flash程序员重写CFI表，则flash程序员将显示一条消息：“内置此设备的覆盖数据”。

在原始的VEEK/T-pad和DE2-115板上有什么闪光灯？

nios2-flash-programmer --epcs --debug --base=0x0a001800 tPad_Selector.flash命令输出什么？
