 ## Debugging the software via Flatsat PC
 Open SSH connection to flatsat PC:
-````
+
+```sh
 ssh eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5
-````
+```
+
 To access the console of the Q7S run the following:
 ```sh
 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.
-````
+
+```sh
 ifconfig
-````
+```
+
 Set IP address and netmask with
-````
+
+```sh
 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.
-````
+
+```sh
 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
-````
+
+   ```sh
+   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
-````
+
+   ```sh
+   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
-````
+   ```sh
+   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
+   ```sh
+   cat > example.service
+   [Unit]
+   Description=Example Service
+   StartLimitIntervalSec=0
 
-[Service]
-Type=simple
-Restart=always
-RestartSec=1
-User=root
-ExecStart=/usr/bin/application
+   [Service] 
+   Type=simple
+   Restart=always
+   RestartSec=1
+   User=root
+   ExecStart=/usr/bin/application
 
-[Install]
-WantedBy=multi-user.target
-````
+   [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.
