Hallo zusammen,
ich habe ein Problem mit QEmu.
Wenn der Emulator startet, stürzt er mitfolgendem Status ab:
Ich vermute mal, dass es am Linker-Script liegt, da es vorher funktioniert hat.
Hier ist auch mal mein Linker-Script.
LD meldet allerdings keine Fehler oder Warnungen.
Woran kann es denn liegen?
Gruß,

Ich vermute mal, dass es am Linker-Script liegt, da es vorher funktioniert hat.
Hier ist auch mal mein Linker-Script.
LD meldet allerdings keine Fehler oder Warnungen.

Woran kann es denn liegen?
