* Generic software components which are not dependant on hardware can also
be run. All host code is contained in the hosted folder
* Tested for Linux (Ubuntu 20.04) and Windows 10
* Raspberry Pi
* EIVE OBC can be built for Raspberry Pi as well (either directly on Raspberry Pi or by installing a cross compiler)
The steps in the primary README are related to the main OBC target Q7S.
## Setting up development environment
* Install Vivado 2018.2 and Xilinx SDK from https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/vivado-design-tools/archive.html.
Install the Vivado Design Suite - HLx Editions - 2018.2 Full Product Installation instead of the updates. It is recommended to use the installer

## 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
````
```sh
writeprotect 0 0 0 # unlocks nominal image on nor-flash 0
````
```
2. Mount the root partition
````
```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
````
```sh
chmod +x application
````
```
5. Create systemd service in /lib/systemd/system. The following shows an example service.
````
```sh
cat > example.service

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.
