Suche Megaload Bootloader-file

[molleonair]

Hallo Leute
kann mir mal bitte jemand n fertig compilierten bootloader schicken
für Mega 16 und 32 mit 16Mhz nur Flash Version 512 Words (kein EEPROM)

bin irgendwie zu blöd die Anpassungen selber zu machen und zu compilen
also irgendwie steht da nirgends beschrieben wie man das comilt so das zum schluß n hex rauskommt,
krieg ständig Fehlermeldungen beim compilen

Vielen Dank Gruß Daniel

Da scheinst du nicht der einzige zu sein, der damit Probleme hat.
Ich kämpfe auch seit Wochen mit dem Teil. Ich mache alles exakt nach vorschrift und kann auch ohne Fehlermeldung compilieren. Nur laufen tut der bootloader nicht. Ich habe nen Atmega8 mit 6MHz, der über nen FT232 an einem USP-Port hängt.
Wenn jemand mal ein gescheites tutorial dafür parat hat, dann wäre ich sehr dankbar. Das Mitgelieferte habe ich 1:1 befolgt und es läuft nicht!

Hallo
also ich hab jetzt lauffähige Bootloader die ich ganz einfach mit nem externen flashtool gestartet bekomme.
Einfach hexfile wählen ,Upload klicken und schon wird mein robbie per Funk-RS232 geproggt.
Einfach nur geil ..

@darxon bei Interesse schick mal PN
PS mein DSL ist grad defekt deshalb bissl geduld haben.

[Jon]

Hast du auch einen für einen ATMEGA8 oder könntest du mir einen anpassen?
Ich verwende einen ATMEGA8 mit 4MHz intern.
Würde mich freuen, wenn du was für mich hast!!

[molleonair]

Welche baudrate ?

[Jon]

19200

P.S.:Damit es 15 Zeichen werden noch dieser sinnlose Text.

hier schaus dir an die änderungen hab ich angepasst
lies dir auch die infos durch

Vielen Dank für den Bootloader!!

öhm ... bootloader in basic .. ich fall vom Glauben ab .. ich dachte daß ist nur was für asm-freaks .... ALLE ACHTUNG .. ich hab mich da noch nicht herangewagt .... und das als Zeh'ler

[MrNiemand]

naja Basic, wandelt der Compiler auch nur in Assembler Befehle ;) .
Ich wäre mal am Gegenstück das auf dem PC interessiert, bzw. Infos darüber, der Bootloader der gepostet wurde, ist ja von Bascom. Aber zumindest in der Hilfe von Bascom konnte ich da leider keine Infos finden.

Ich bin momentan dabei, mir den Bootloader für I2C umzuschreiben,deswegen wären da ein paar Infos über die Verarbeitung der Hex Files usw.
