### Debugging the software via Flatsat PC
Open SSH connection to flatsat PC:
````
ssh eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5
````
To access the console of the Q7S run the following:
````
sudo picocom -b 115200 /dev/ttyUSB0
````
To debug an application, first make sure a static IP address is assigned to the Q7S. Run ifconfig on the Q7S serial console.
````
ifconfig
````
Set IP address and netmask with
````
ifconfig eth0 192.168.133.10
ifconfig eth0 netmask 255.255.255.0
````
To launch application from Xilinx SDK setup port fowarding on the localhost.
````
ssh -L 1534:192.168.133.10:1534 eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5
````
This forwards any requests to localhost:1534 to the port 1534 of the Q7S with the IP address 192.168.133.10.
Note: When now setting up a debug session in the Xilinx SDK, the host must be set to localhost instead of the IP address
of the Q7S.
### Launching an application after boot
Load the root partiton from the flash memory (there are to nor-flash memories and each flash holds two xdi images).
Note: It is not possible to modify the current loaded root partition.
1. Disable write protection of the desired root partition
````
writeprotect 0 0 0 # unlocks nominal image on nor-flash 0
````
2. Mount the root partition
````
xsc_mount_copy 0 0 # Mounts the nominal image from nor-flash 0
````
3. Copy the executable to /bin/usr
4. Make sure the permissions to execute the application are set
````
chmod +x application
````
5. Create systemd service in /lib/systemd/system. The following shows an example service.
````
cat > example.service
[Unit]
Description=Example Service
StartLimitIntervalSec=0
[Service]
Type=simple
Restart=always
RestartSec=1
User=root
ExecStart=/usr/bin/application
[Install]
WantedBy=multi-user.target
````
6. Enable the service. This is normally done with systemctl enable. However, this is not possible when the service is
created for a mounted root partition. Therefore create a symlink as follows.
````
ln -s '/tmp/the-mounted-xdi-image/lib/systemd/system/example.service' '/tmp/the-mounted-xdi-image/etc/systemd/system/multi-user.target.wants/example.service'
````
7. The modified root partition is written back when the partion is locked again.
````
writeprotect 0 0 1
````
8. Now verify the application start by booting from the modified image
````
xsc_boot_copy 0 0
````
9. After booting verify if the service is running
````
systemctl status example
````
More detailed information about the used q7s commands can be found in the Q7S user manual.
### Update file in rootfs
````
writeprotect 0 0 0 # qspi0 nom unlock (see also Q7S user manual)
````
### Setting up UNIX environment for real-time functionalities
Please note that on most UNIX environments (e.g. Ubuntu), the real time functionalities
used by the UNIX pthread module are restricted, which will lead to permission errors when creating these tasks
