-# Arduino-Bootloader (STK500) für Nano-1284
-
-Dieser Bootloader ermöglicht die Programmierung über das "Arduino-System". Als Kommunikationsprotokoll kommt das [STK500 Protokoll]( https://www.microchip.com/content/dam/mchp/documents/OTH/ApplicationNotes/ApplicationNotes/doc2525.pdf) zur Anwendung (Kommunikationsablauf siehe Datei [protocol](protocol)).
-
-Beim Bootloader in [src/main.c](src/main.c) handelt es sich um eine Anpassung von [https://github.com/arduino/ArduinoCore-avr/blob/master/bootloaders/atmega/ATmegaBOOT_168.c](https://github.com/arduino/ArduinoCore-avr/blob/master/bootloaders/atmega/ATmegaBOOT_168.c) an die Hardware des Nano-1284 Boards.
-
-Diese Anpassung der Quelltext-Datei umfasst:
-* Microcontroller ATmega1284P (mit 128KiB Flash, davon die hinteren 8KiB für den Bootloader)
-* Frequenz 12MHz
-* 3 LEDs (rot, gelb, grün)
-* Assembler-Anweisungen durch Macros aus `avr/boot.h` ersetzt
-* Quelltextkorrekturen, damit der Bootloader auch bei einer Page-Size von 256 Byte funktioniert
-
-Der Bootloader kann entweder selbst aus der Quelltextdatei erzeugt werden (siehe [Übersetzung](#%C3%BCbersetzung)), oder es wird eine der bereits fertigen Dateien im Ordner [release](release) verwendet:
-* [release/bootloader-arduino_nano-1284.elf](release/bootloader-arduino_nano-1284.elf)
-* [release/bootloader-arduino_nano-1284.hex](release/bootloader-arduino_nano-1284.hex)
-
-## Übersetzung
-
-Folgende Tools sind erforderlich:
-* avr-gcc
-* avrdude
-
-Auf einem Linux-Debian System müssen daher folgende Pakete installiert sein:
-```sh
-sudo apt update
-sudo apt install gcc-avr avr-libc binutils-avr avrdude
-```
-
-Die Übersetzung erfolgt dann mit dem Kommando `make`.
-
-## Download auf den µC
-
-Die korrekte Programmierung der Fuses sowie der Download des Bootloaders in den Bootloader-Bereich des µC-Flash kann mit Hilfe eines [USBasp-Programmiergeräts](https://www.fischl.de/usbasp/) mit folgenden Kommandos erfolgen:
-
-```sh
-make isp-fuse
-make isp-flash
-```
-
-Nach der Programmierung sollten die drei LEDs den Start des Bootloader anzeigen (rot -> rot+orange -> grün -> grün blinken).
-
-
-## Download von Programmen mit Hilfe des Bootloaders
-
-Sobald sich am µC ein Bootloader befindet ist kein Programmiergerät mehr erforderlich. Das Programm wird über die serielle UART-Schnittstelle (via USB-Schnittstelle) in den Flash gespeichert.
-
-UART-Schnittstelle (Option `-P`) und Name der ELF-Programmdatei (nach `flash:w:`) sind anzupassen...
-
-```sh
-avrdude -c arduino -p m1284p -P /dev/ttyUSB0 -b 115200 -e -U flash:w:programm.elf
-```
-
-## Einbindung in die Arduino IDE
-
-Zunächst den Ordner mit der Arduino Installation finden. Unter Linux ist das der Pfad:
-```
-/usr/share/arduino/hardware/arduino/avr
-```
-
-Dort im Unterordner `bootloaders` einen Ordner `atmeg1284` anlegen und darin die Intel-Hex Datei des Bootloaders ablegen.
-
-```sh
-make
-sudo mkdir /usr/share/arduino/hardware/arduino/avr/bootloaders/atmega1284
-cp dist/bootloader-arduino_nano-1284.hex /usr/share/arduino/hardware/arduino/avr/bootloaders/atmega1284/
-```
-
-Danach in der Datei `/usr/share/arduino/hardware/arduino/avr/boards.txt` folgende Einträge ergänzen:
-```

+# Arduino-Bootloader (STK500) für Nano-1284
+
+Dieser Bootloader ermöglicht die Programmierung über das "Arduino-System". Als Kommunikationsprotokoll kommt das [STK500 Protokoll]( https://www.microchip.com/content/dam/mchp/documents/OTH/ApplicationNotes/ApplicationNotes/doc2525.pdf) zur Anwendung (Kommunikationsablauf siehe Datei [protocol](protocol)).
+
+Beim Bootloader in [src/main.c](src/main.c) handelt es sich um eine Anpassung von [https://github.com/arduino/ArduinoCore-avr/blob/master/bootloaders/atmega/ATmegaBOOT_168.c](https://github.com/arduino/ArduinoCore-avr/blob/master/bootloaders/atmega/ATmegaBOOT_168.c) an die Hardware des Nano-1284 Boards.
+
+Diese Anpassung der Quelltext-Datei umfasst:
+* Microcontroller ATmega1284P (mit 128KiB Flash, davon die hinteren 8KiB für den Bootloader)
+* Frequenz 12MHz
+* 3 LEDs (rot, gelb, grün)
+* Assembler-Anweisungen durch Macros aus `avr/boot.h` ersetzt
+* Quelltextkorrekturen, damit der Bootloader auch bei einer Page-Size von 256 Byte funktioniert
+
+Der Bootloader kann entweder selbst aus der Quelltextdatei erzeugt werden (siehe [Übersetzung](#%C3%BCbersetzung)), oder es wird eine der bereits fertigen Dateien im Ordner [release](release) verwendet:
+* [release/2024-09-05_120945/bootloader-arduino_nano-1284.elf](release/2024-09-05_120945/bootloader-arduino_nano-1284.elf)
+* [release/2024-09-05_120945/bootloader-arduino_nano-1284.hex](release/2024-09-05_120945/bootloader-arduino_nano-1284.hex)
+
+## Übersetzung
+
+Folgende Tools sind erforderlich:
+* avr-gcc
+* avrdude
+
+Auf einem Linux-Debian System müssen daher folgende Pakete installiert sein:
+```sh
+sudo apt update
+sudo apt install gcc-avr avr-libc binutils-avr avrdude
+```
+
+Die Übersetzung erfolgt dann mit dem Kommando `make`.
+
+## Download auf den µC
+
+Die korrekte Programmierung der Fuses sowie der Download des Bootloaders in den Bootloader-Bereich des µC-Flash kann mit Hilfe eines [USBasp-Programmiergeräts](https://www.fischl.de/usbasp/) mit folgenden Kommandos erfolgen:
+
+... oder die aktuellste Version im UNterordner [release](release) ...
+
+```sh
+make isp-fuse-1284p
+make isp-flash-1284p-latest-release:
+```
+
+Nach der Programmierung sollten die drei LEDs den Start des Bootloader anzeigen (rot -> rot+orange -> grün -> grün blinken).
+
+
+## Download von Programmen mit Hilfe des Bootloaders
+
+Sobald sich am µC ein Bootloader befindet ist kein Programmiergerät mehr erforderlich. Das Programm wird über die serielle UART-Schnittstelle (via USB-Schnittstelle) in den Flash gespeichert.
+
+UART-Schnittstelle (Option `-P`) und Name der ELF-Programmdatei (nach `flash:w:`) sind anzupassen...
+
+```sh
+avrdude -c arduino -p m1284p -P /dev/ttyUSB0 -b 115200 -e -U flash:w:programm.elf
+```
+
+## Einbindung in die Arduino IDE
+
+Zunächst den Ordner mit der Arduino Installation finden. Unter Linux ist das der Pfad:
+```
+/usr/share/arduino/hardware/arduino/avr
+```
+
+Dort im Unterordner `bootloaders` einen Ordner `atmeg1284` anlegen und darin die Intel-Hex Datei des Bootloaders ablegen.
+
+```sh
+make
+sudo mkdir /usr/share/arduino/hardware/arduino/avr/bootloaders/atmega1284
+cp dist/bootloader-arduino_nano-1284.hex /usr/share/arduino/hardware/arduino/avr/bootloaders/atmega1284/
+```
+
+Danach in der Datei `/usr/share/arduino/hardware/arduino/avr/boards.txt` folgende Einträge ergänzen:
+```
