Fehler im Assembler-Code

**dark emporer** · 09.08.2005, 15:04

Ich habe bis jetzt mit win-avr in c programmiert habe eigentlich auch asambler kenntnisse. Jetz habe ich ein ferdiges code runtergeladen doch da war nur die *.asm drinne. Wie kann man die Compilieren? Win-Avr müsste das können aber ich brauche warscheinlich eine ander makefile oder soll ich anderen compiler nehmen?

Ich habe mir erlaubt den Titel von "asaembler" in "Fehler im Assembler-Code" umzuschreiben, das klingt einfach korrekter und alle wissen, worum es geht! ;o)

Viele Grüße
Florian (Moderator)

habe mich vertippt

Danke

Hallo,

ich compilier die *.asm-Dateien immer mit dem AVR-Studio. Daraus wird dann eine *.hex-Datei, die du dann mit TwinAVR (oder ähnlichem) auf deinen Chip brennen kannst.

AVR-Studio bekommst du hier

Gruß
Thomas

Hmm..sorry, so gut kann ich Assembler auch nocht nicht.
Aber der Fehler muss wohl irgendwie in ".section" liegen.

Was passiert denn, wenn du vor der Zeile ".section .text " mal ein ";" machst? (also auskommentierst) Die Zeile steht ziemlich oben im Code.
Ich glaub nicht, dass es was hilft, aber ich find im Code auch nirgends die Wörter "section" oder "text" wieder.

**izaseba** · 09.08.2005, 15:51

Hallo,
was mir da nicht gefällt sind die direktiven .section .text (dem assembler gefällt es auch nicht)

C:\WINDOWS\system32\dss.asm(69): error: Invalid directive: '.section'

Kommentiere die Zeile aus und schaue, was dann passiert.

Gruß Sebastian

Edit: Toeoe war etwas schneller, aber den gleichen gedanken gehabt
