我正在遵循this guide进行手臂仿真设置。该指南以连接机为例制作。我想遵循该指南，但是使用xilinx-zynq-a9机器，因为我有一些使用zynq板的经验。
因此，按照本教程，我制作了一个.bin文件。在本教程中，它说连接板具有16MB闪存，并且CPU从地址0x0开始执行。但这不是zynq SoC的情况，它具有OCM（片上内存）（bootrom + RAM），因此，如果我要运行应用程序，通常会将程序下载到OCM并重置板以开始执行。 / p>
下面是我执行的命令及其输出：

FPSCR: 00000000
如所见，代码未加载到0x0位置，是否有任何方式可以为qemu“编程” zynq的OCM，就像我们使用dd工具编程flash一样？ 该模型是否也从OCM开始执行？或者有什么不同？
