Bootloader will nicht funktionieren

[masterchief]

Hy

Ich möchte meinen Atmega32 auf dem Pollinboard mit nem Bootloader versehen...ich hab ihn draufgemacht und wollte ab nun in Bascom über MCS Bootloader proggn...aber es funkt einfach nicht!!
Ich hab die Fuses richtig mit PonyProg gesetzt und auch über PonyProg den Bootloader draufgemacht...aber über Bascom kommt nur folgendes:
Open Com
Sending Init Byte
und dann gehts nicht mehr weiter...
Hab auch die Baudrate richtig auf 19200 eingestellt...ich hab echt keinen Plan was da los ist...
Hoffe ihr könnt mir helfen!
Danke schon mal im voraus!!

Da hätten wir schon mal das erste Problem: es gibt nicht nur 1 Bootloader.
Also welcher genau isses?

[masterchief]

Den hab ich aus einem Forum: Bei Bascom ist der Bootloader.bas enthalten...meiner ist der selbe nur das er schon kompiliert ist und die Baudrate auf 19200 umgestellt wurde...

edit: könnte es daran liegen das Bascom mit meinem RS232 zu USB-Kabel nicht zurechtkommt?

[Jaecko]

Und in der kompilierten Version ist auch der richtige Controller ausgewählt?
Ich würd bei sowas eher keine fertige .hex verwenden, sondern immer selber kompilieren.

[masterchief]

Ich habs mir vorher noch mal durchgelesen...der Atmega32 ist eingestellt und auch die Baudrate stimmt...
Hier ist der Code:

Er müsste eigentlich richtig sein...

So aufs erste fällt mir da kein Fehler auf.
Haben PC und AVR schon mal miteinander kommuniziert?
Um das zu testen, einfach mal ein einfaches Programm ohne Bootloader etc. schreiben, welches was sendet und am PC mit nem Terminal-Programm schauen, ob überhaupt was ankommt.

Irgendwas in der Art

Do
 Print "Test"
 Wait 1
Loop

sollts tun.

[masterchief]

Ich progge schon ne ganze Weile aber bis jetzt nur über PonyProg. Hab schon selbst Programme geschrieben und die haben wunderbar geklappt.
Bis jetzt hats aber immer 1,5 Stunden gedauert darum wollte ich alles über Bascom und den Bootloader machen.

Ps: Ich kann den Bootlaoder leider selbst momentan nicht kompilieren, da ich nur dei Testversion habe und er beim kompilieren ne Fehlermeldung ausgibt.

mfg masterchief

[Bammel]

was ahtd en 1,5 stundne gedauert? da kompilieren? oder übertragen? das wäre arg krass und iwas wäre falsch eingestellt.

wenn das sending init byte kommt resete das board mal einmal.

[mat-sche]

Hi,

bevor der Bootlader in den M32 übertragen wird, musst du ihn dazu resetten.
Bascom fragt nun den Com-Port ab, ob auf seine Anfrage (init byte 123) eine Antwort vom Mega kommt.
Es scheint so, dass er die Antwort vom Mega nicht bekommt und deshalb schon hier stehen bleibt.
Kann es nicht doch sein, dass deine Fuse nicht stimmen oder der Bootloader nicht richtig installiert ist?
Läuft Dein Board auch mit nen 16mhz quarz?
Bei mir sind folgende Fuse gesetzt: eesave, bootsz1, boottrst.
Vergleiche mal dein device über Ponyprog unter read device bei der Adresse beginnend bei 00780) bis 007e20) ob dort was drin steht.
MAT

[masterchief]

hab das board resettet...geht trotzdem nicht
Das schreiben des Programms geht in ca. 10 - 20 Sekunden...das "Verifying" dauert so lange.
Das Board selbst läuft mit den vollen 16Mhz. Ich hab über den Fusecalculater alles eingestellt...ich probiers nochmal mit deinen Fuses und probiers morgen noch mal aus.

Ps: Da ich über ein USB zu RS232 Kabel progge, kann es sein das Bascom mit meinem Kabel nicht zurechtkommt?
