Embedded JTAG上的系统控制台无法执行master_write_32—；can'；目标正在运行时，是否不执行此操作？

我有一个用Verilog编写的简单控制器，用于配置Altera的TSE MAC。到目前为止，这是相当简单的。然而，我下一步要做的是设置许多Marvel PHY的设置，并持续监控PHY和MAC的统计数据和错误等。在硬件中这样做似乎是一种过激行为，因此我决定合并一个Nios CPU。但在继续在软件中实现该组件之前，我想使用系统控制台快速实现该想法的原型。无论如何，这是我的QSys基本系统：

MAC实例被称为

tse_MAC

，其思想是通过CPU的

data_master

读/写

control_port

来配置它

在系统启动并运行之后，我使用系统控制台连接到它。我假设它通常可以工作，因为它能够获得

主服务路径：

% get_service_paths master
{/devices/EP2AGX260@1#7-1/(link)/JTAG/(70:34 v3 #0)/nios2_0}

它也开得很好。但是，当尝试写入32位值时，它会立即失败：

% get_service_paths master
{/devices/EP2AGX260@1#7-1/(link)/JTAG/(70:34 v3 #0)/nios2_0}
% open_service master "/devices/EP2AGX260@1#7-1/(link)/JTAG/(70:34 v3 #0)/nios2_0"

% master_write_32 "/devices/EP2AGX260@1#7-1/(link)/JTAG/(70:34 v3 #0)/nios2_0" 0x400 0x00000000;
error: com.altera.systemconsole.internal.plugin.jtag.oci.Nios2DebugException: Can't do this while target is running
    while executing
"master_write_32 {/devices/EP2AGX260@1#7-1/(link)/JTAG/(70:34 v3 #0)/nios2_0} {0x400} {0x00000000}"
    while executing
"master_write_32 "/devices/EP2AGX260@1#7-1/(link)/JTAG/(70:34 v3 #0)/nios2_0" 0x400 0x00000000"
% 

例外情况如下：

我以前从未使用过System Console，在Internet或手册中找不到任何相关内容。所以问题是——我犯了什么错误？非常感谢您对解决此问题的任何帮助。
异常意味着您必须暂停/停止CPU以执行
master\u write\u 32
。要保持CPU运行，必须使用。它将作为另一个服务（即索引1）导出，并可用于与Avalon MM组件通信。答案的功劳在于
