Running XAPP1079 on a Zynq Board - fpga

Question

I am trying to run the XAPP 1079 on a Zynq Board (xc7z010clg400-1). Because the profile is not originally made for this specific board, I had to make some changes. I follow all the insructions for the Vivado and the SDK, but in the end after the board boots from the microSD card I don't see anything in the terminal. I was wondering first if the changes that I made are correct and if anymore are needed.
One specific issue I am having is that while creating an instance of the Zynq7 processor, it uses the configuration preset for the ZC702 board. Can/Should I change that?
# 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
Also, while running the tcl scripts a warning appears.
[BD 41-1731] Type mismatch between connected pins: /ila_0/probe2(undef) and /irq_gen_0/IRQ(intr)
You can see the files for this profile here.
Below are the two files that I have created after modifying the Xilinx ones. I should add that I'm using the 2017.1 version of Vivado.

Answer 1

I have managed to make XAPP1079 run on Zybo with changes in the tcl script responsible for the block design and some changes in the c file that the CPU0 runs.
As far as the tcl script for block design is concerned, I copied the configs from the configuration preset for the Zybo and pasted them in the property list of the instance of processing_system7_0 in the code.
Here is the code snippet. It is abbreviated because it is too large to post.
# 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
As far the .c file for CPU0, I followed this post.
I changed the part that would reset CPU1,
{
/*
* Reset and start CPU1
*- Application for cpu1 exists at 0x00000000 per cpu1 linkerscript
...
...
...
}
with this code.
#define CPU1STARTADR 0xfffffff0
#define sev() __asm__("sev")
print("CPU0: writing startaddress for cpu1\n\r");
print("CPU0: writing startaddress for cpu1\n\r");
Xil_Out32(CPU1STARTADR, 0x00200000);
dmb(); //waits until write has finished
print("CPU0: sending the SEV to wake up CPU1\n\r");
sev();
Now when I debug the application projects in the SDK, I can see continuous Hello Worlds from both CPUs. Despite that the part of the application note about the interrupt doesn't seem to work.
