我正在尝试在Zynq板上运行XAPP 1079(XC7Z010CLG400-1(。因为该配置文件最初不是为此特定板制作的，所以我必须进行一些更改。我遵循了Vivado和SDK的所有距离，但是最后，在MicroSD卡的董事会启动后，我在终端中没有看到任何东西。我首先想知道我所做的更改是否正确以及是否需要。
我遇到的一个特定问题是，在创建Zynq7处理器的实例时，它使用ZC702板的配置预设。我应该/应该更改吗？
# Create instance: processing_system7_0, and set properties
set processing_system7_0 [ create_bd_cell -type ip -vlnv xilinx.com:ip:processing_system7:5.5 processing_system7_0 ]
set_property -dict [ list CONFIG.PCW_CORE1_IRQ_INTR {1} CONFIG.PCW_USE_FABRIC_INTERRUPT {1} **CONFIG.preset {ZC702}** ] $processing_system7_0
另外，在运行TCL脚本时会出现警告。
[BD 41-1731] Type mismatch between connected pins: /ila_0/probe2(undef) and /irq_gen_0/IRQ(intr)
您可以在此处看到此配置文件的文件。
以下是我修改Xilinx之后创建的两个文件。我应该补充一点，我正在使用2017.1版的Vivado。

我已经设法使XAPP1079在Zybo上运行，其TCL脚本负责块设计的更改以及CPU0运行的C文件中的某些更改。
就块设计的TCL脚本而言，我复制了Zybo的配置预设中的配置，并将其粘贴到代码中的processing_system7_0实例的属性列表中。
。这是代码段。它缩写是因为它太大而无法发布。
# Create instance: processing_system7_0, and set properties
set processing_system7_0 [ create_bd_cell -type ip -vlnv xilinx.com:ip:processing_system7:5.5 processing_system7_0 ]
set_property -dict [ list CONFIG.PCW_DDR_RAM_BASEADDR {0x00100000}
CONFIG.PCW_DDR_RAM_HIGHADDR {0x1FFFFFFF}
.
.
.
CONFIG.PCW_PLL_BYPASSMODE_ENABLE {0}
CONFIG.preset {Default*}
] $processing_system7_0
到CPU0的.c文件，我遵循了这篇文章。
我更改了将重置CPU1的部分
{
/*
* Reset and start CPU1
*- Application for cpu1 exists at 0x00000000 per cpu1 linkerscript
...
...
...
}
使用此代码。
#define CPU1STARTADR 0xfffffff0
#define sev() __asm__("sev")
print("CPU0: writing startaddress for cpu1nr");
print("CPU0: writing startaddress for cpu1nr");
Xil_Out32(CPU1STARTADR, 0x00200000);
dmb(); //waits until write has finished
print("CPU0: sending the SEV to wake up CPU1nr");
sev();
现在，当我在SDK中调试应用程序项目时，我可以看到两个CPU的连续Hello World。尽管申请注释的一部分关于中断似乎不起作用。
