Linux AM335x启动器套件使用qemu进行模拟

我有，但最近它没有启动。按下reset键后，电源指示灯不会发光[只会亮起几分之一秒]，LCD屏幕显示灰白色显示，之后什么也没有显示）

同时,， 我已经制作了一些定制应用程序，用Linux在主板上进行测试。想知道我是否可以使用qemu模拟器模拟/模拟电路板

我做了类似的事情（现在使用了预构建的内核映像，它是linux SD卡附带的）。因为这是Cortex a8，所以将-M命名为realview-pb-a8。尝试了此命令的其他几个变体，但仍存在此错误。请建议使用适当的命令使用模拟器测试/模拟电路板

我想在设备上测试应用程序，但由于它没有启动，我什么都做不了。我的目标是模拟SDK附带的AM335x设备的Linux内核，而不使用实际的硬件，包括matrix GUI和其他应用程序；所以我可以在这个基础上建立

有人能帮我吗

感谢和问候

ARM有限公司Cortex-A8测试芯片绝对不是TI AM335x，RealView PB板上的任何非芯片材料也不可能与TI开发板上的任何材料完全相同。与此类似，你会认为车身面板和其他部件能够安装一个发动机，仅仅因为它们具有相同的基本发动机吗？@不一样，谢谢你的回答。我相信“这是一个基于ARM®Cortex的低成本开发平台™-A8处理器”，摘自此处：您能建议我使用qemu系统arm或任何其他arm模拟器模拟电路板的步骤吗。我不确定上述命令是否由于机器参数不正确或其他原因而失败。再次感谢您的帮助。我建议，模拟电路板的第一步是不要模拟一些完全不同的、不兼容的电路板——CPU核心只是系统的一个很小的方面（在这种情况下几乎不相关）。将与AM3358 SoC进行比较，注意两者之间几乎没有相同之处。如果您想为基于AM3358的系统运行代码，您至少需要模拟一些基于AM3358的系统。
