# ⚡️ RaspiBlitz-on-DietPi ⚡️
#  A hardware agnostic platform


This guide was tested on:

* Odroid HC1
* Odroid HC2 (the same board except it accommodates a 3.5" 12V HDD)
* Raspberry Pi 3 B Plus - no LCD support so far
* hoping to extend this list with more compatible boards especially the ROCK64  

See the [hardware comparison](hw_comparison.md).

## General guide for the RaspiBlitz-on-DietPi 

### Setting up the DietPi OS

* Start with an ARM based Single Board Computer listed on DietPi.com.  
At least 1GB RAM is recommended.  
Look for the SD card image for the specific SBC in the [download section](https://dietpi.com/#download).

* Burn the image to the SDCard with [Etcher](https://www.balena.io/etcher/) and extend the rootfs partition to the size of your card with a partition manager.

* Insert the SDcard into your SBC.

* Connect the HDD with a powered suitably powered adapter.
A USB 2.0 port will not be able to power an HDD so you will need extra cable
If you are connecting the HDD to a USB 3.0 port and have an at least 2A power supply, you might be able to run without an extra cable.

* Power up and continue with: [Run the DietPi optimized Raspiblitz SDcard build script](#Run-the-RaspiBlitz-build_sdcard.sh-script)


 
* In the desktop terminal on Linux / MacOS or Putty on Windows:  
`ssh root@[IP-OF-DIETPI]`  
password: `dietpi`  
Getting started with DietPi: https://dietpi.com/phpbb/viewtopic.php?f=8&t=9#p9 

* You might be asked about updating DietPi. This might not be straightforward if starting froma  version <6.20. Try to update, it is best to build on the latest version.

* In the DietPi software menu install fail2ban and make OpenSSH server the default SSH server.
Changing the SSH server will change the SSH keys again. To clear:  
`ssh-keygen -f "/home/[your-linux-username]/.ssh/known_hosts" -R "dietpi.IP"`

* After every reboot log back in:  
`ssh root@[IP-OF-DIETPI]`  
password: `dietpi`

* Should end up here on version v6.20.6 or higher:

### Run the RaspiBlitz build_sdcard.sh script

* Format of the command to build the SDcard:  
`wget https://raw.githubusercontent.com/[GITHUB-USERNAME]/raspiblitz/[BRANCH]/build_sdcard.sh && sudo bash build_sdcard.sh [BRANCH] [GITHUB-USERNAME]`  
If you are working from a forked repo be aware of that the fork needs to be called `raspiblitz` for the git downloads to work.

* Run the forked version of @openoms:  
`wget https://raw.githubusercontent.com/openoms/raspiblitz/raspiblitz-dev/build_sdcard.sh && sudo bash build_sdcard.sh raspiblitz-dev openoms`  
This will take a couple minutes depending on your internet ceonnection and the processing power of the SBC.

* Restart when done and log back in now as `admin`:  
`ssh admin@[IP-OF-DROIDBLITZ]`  
password: `raspiblitz`

* From here he setup continues with the [RaspiBlitz Setup Process](https://github.com/rootzoll/raspiblitz/blob/master/README.md#setup-process-detailed-documentation)

### Useful commands for debugging:
To test a new configuration run XXcleanHDD.sh and strictly restart
(this makes _bootstrap.sh and 00mainMenu.sh run in the right order)

`tail -n1000 -f /var/tmp/dietpi/logs/dietpi-automation_custom_script.log` follow startup setup script log  
`lsblk` see the partitions  
`tail -n1000 -f raspiblitz.log` - debug logs of bootstrap.sh  
`sudo tail -f /mnt/hdd/bitcoin/debug.log` - continuous monitoring  
`sudo tail -n100 /mnt/hdd/bitcoin/debug.log` - shows the last 100 lines  
`sudo systemctl status lnd`  
`sudo journalctl -f -u lnd`  
`./home/admin/XXdebugLogs.sh` - debug log collection on the RaspiBlitz

## Excerpts from the default [dietpi.txt](https://github.com/Fourdee/DietPi/blob/master/dietpi.txt)
to be used for a fully automatic SDcard building process.

### Automate installation with the dietpi.txt
Need to copy to SDcard /boot/dietpi.txt after burning the image with Etcher.
IMPORTANT:
- Modifications to /boot/dietpi.txt will not be preserved on reboot.
- Please ensure you edit from the DietPi-RAMdisk location: /DietPi/dietpi.txt
NB: This is intended for advanced users, unless you know what you are doing, do not edit this file. ease use the DietPi programs instead.
NB: Do not remove uncommented lines, as the items are scraped by DietPi programs, on demand.
DietPi-Automation settings, applied on the 1st boot of DietPi, ONCE
Sample:
https://github.com/Fourdee/DietPi/blob/master/dietpi.txt

### DietPi-Software to automatically install.  
Requires `AUTO_SETUP_AUTOMATED=1  `
For a list of software index's (ID's), run '/DietPi/dietpi/dietpi-software list'  
No limit on number entries, add as many as you need and uncomment the line.  
DietPi will automatically install all pre-reqs (eg: ALSA/XSERVER for desktops etc)  
>install fail2ban  
AUTO_SETUP_INSTALL_SOFTWARE_ID=73  
install OpenSSH Client  
AUTO_SETUP_INSTALL_SOFTWARE_ID=0  
install OpenSSH Server  
AUTO_SETUP_INSTALL_SOFTWARE_ID=105  


### Custom Script (post-networking and post-DietPi install) 
Runs after DietPi installation is completed
Allows you to automatically execute a custom script at the end of DietPi installation.  
Option 1 = Copy your script to /boot/Automation_Custom_Script.sh and it will be executed automatically.  
Option 2 = Host your script online, then use AUTO_SETUP_CUSTOM_SCRIPT_EXEC=http://myweb.com/myscript.sh, it will be downloaded and executed automatically. | 0=disabled  
NB: Executed script log /var/tmp/dietpi/logs/dietpi-automation_custom_script.log
