Atmega32 reagiert nicht mehr nach fuse Änderung

[Richard]

Da ich das RN-Control Board benutze habe ich doch automatisch einen 16 Mhz Quarz betriebsbereit oder?

Zumindest die neueren RN_Control haben eigentlich einen Bootloader so das sie über RS232 Programmiert werden können.

Der ist allerdings in der Regel "Wech" wenn der Chip über ISP programmiert wird........

Mit der Ausgabe von Deinem Brenner komme (ich) nicht klar, ich benutze AVR Studio da bekomme ich die Fuse Einstellungen in Klartext.
Mit einem Datenblatt sollte man aber finden können was und Wo gesetzt sein sollte.

Hi,

also ich hab jetzt mal ein bischen rumprobiert und mittels des Online fuse calculator:

http://www.engbedded.com/fusecalc/

CKOPT bei meinem funktionierenden mega32 aktiviert und auf externen Quarz umgestellt. Ich hab dann versucht das Signal des funktionierenden von XTAL2 auf XTAL1 des anderen zu legen und einfach mal ein Programm zu überspielen, dass einen PORT auf Output stellt. Leider kommt da nichts.

Ich hab aber auch einfach mal interessehalber mit avrdude die fuses des funktionierenden ausgelesen und so wie ich das sehe, kommt da genau das selbe raus wie bei dem anderen. Das würde darauf schließen, dass sie sich mit dem Programmer nicht richtig auslesen lassen oder?

avrdude -p atmega32 -c AVR910 -P /dev/ttyUSB0 -v -U lfuse:r:-:i -F

avrdude done.  Thank you.

Was ich auch noch komisch finde, dass ich immer den Befehl -F benutzen muss, weil scheinbar die Signatur des megas nicht stimmt. Ist das ein Fehler? Ohne Force Parameter sieht der Output so aus:

avrdude done.  Thank you.

Wenn die Signatur nicht richtig erkannt wird, dann ist irgendwo der Wurm drinnen. Wenn du dann trotzdem Programmierst dann kann allerhand Unsinn im Kontroller stehen.
Hast du ein anderes Board zum Programmieren? Damit du testen kannst ob der Programmer defekt ist oder das Board.

Also das er die Signatur nicht richtig erkannt hat war schon immer so. Ich musste immer per -F forcen. Ich hab den Programmer mit zwei verschiedenen megas benutzt und hab beide ne ganze weile damit programmiert, bis der eine halt nicht mehr ging...Bei beiden wurde die Signatur nicht erkannt.
Es kommt auch öfter vor, dass ich das Programm zwei mal hintereinander übertragen muss, weil sonst nichts passiert.

Hallo,
versuche doch einmal langsamer zu übertragen.
Wenn ich Fuses übertrage, dann noch mit "-B 10" in der Kommandozeile.
Ich verwende den USBasp-Adapter.
Ein frischer Atmega kommt anfangs bei normaler Übertragungsgeschwindigkeit irgendwie nicht mit.
Nur wenn ich noch -B 10 anfüge, funktioniert das.
Wenn die Fuses dann einmal entsprechend gesetzt wurden, kann der Atmega auch die normale Geschwindigkeit über ISP vertragen.

Wenn die Signatur nicht richtig erkannt wird, heißt dass das die Verbindung über die ISP Schnittstelle nicht sicher funktioniert. Da man wohl was einigermaßen sinnvolles Auslesen kann und ggf. auch schreiben kann, ist es hier wohl so das es gerade an der Grenze ist. In diesem Fall sollte man erstmal klären woran das liegt.

Bevor man keine zuverlässige Verbindung hat, sollte man nicht auf den µC schreiben. Es kann dann nämlich auch mal versehentlich was anderes als geplant geschrieben werden. Schreiben mit einer schlechten Verbindung ist riskant. Wenn man ganz viel Pech hat, kann sogar schon beim "lesen" was passieren - da sind die Gefahren aber meist kleiner.

Die Option -F sollte man auch mit viel Vorsicht (z.B. für neuen noch nicht unterstützten µC Typ) nutzen. Da ist immer ein Risiko dabei, selbst wenn die Verbindung sonst stabil läuft.

Mhh, also an der verkabelung sollte es eigentlich nicht liegen, das ist son wannenstecker, da müsste das problem schon direkt auf der platine vom Programmer liegen. Oder auf dem rn boad.
BMS hat ja schon dir geschwindigkeit angesprochen, mein ihr das könnte etwas bewirken? Was genau bringt -B 10? Hab leider grade keinen zugang zur man page von avrdude.

-B bitclock
Specify the bit clock period for the JTAG interface or the ISP clock (JTAG ICE only). The value is a floating-point number in microseconds. The default value of the JTAG ICE results in about 1 microsecond bit clock period, suitable for target MCUs running at 4 MHz clock and above. Unlike certain parameters in the STK500, the JTAG ICE resets all its parameters to default values when the programming software signs off from the ICE, so for MCUs running at lower clock speeds, this parameter must be specified on the command-line.

Quelle: AVRDUDE: 2.1 Option Descriptions

-B 10 bedeutet also 10µSekunden Taktperiode (=100kHz ISP Clock maximal).
Vielleicht muss es auch noch langsamer sein, z.B. wären -B 100 ja 100µSekunden, also 10kHz ISP Clock maximal, da MUSS es ja dann funktionieren, sonst ist etwas am Programmieradapter oder der Kabelverbindung faul !

Also wie schon geschrieben, Fuses übertragen bei neu gekauften Atmegas ging bei mir (über USBasp) NUR mit dem Zusatz "-B 10" in der Kommandozeile von avrdude.
