Discovery_STM32F746 Linking Problem

Aber ein .bin File hast Du nach dem compilieren ?
Ev. macht dir das Makefile aus dem .elf File automatisch ein .bin File
Auszug aus dem Makefile:

1

$(PRJ).bin:  $(LPRJ).elf

2

  $(ECHO) "  [OBJC] $@"

3

  $(OS) $<

4

  $(OC) -v -O binary $< $(PRJ).bin

Dann findet arm-none-eabi-size das .elf File nicht mehr.

Hallo Daniel,
hallo hp-freund,
und Forum!

Dass ein .bin File automatisch aus dem .elf File
erzeugt wird ist mir klar, steht ja so im Makefile.
Leider kommt es nicht dazu, da kein elf File erzeugt
wird.

Ich habe schon make mit --debug=vij aufgerufen, erhalte
leider aber keine Hinweise zum Problem.
Was mich etwas verunsichert, sind die vielen Meldungen
im Map-File, das Symbole mehrfach definiert sind.

z.B.:

first defined here
audio_play.o: In function `AUDIO_Start':
audio_play.c:(.text.AUDIO_Start+0x0): multiple definition of


Ich habe um sicher zu gehen, einen find auf .elf laufen lassen,
aber kein solches File gefunden.

Andere Projekte compilieren aber z.B. auf der Discovery_STM32F429
ohne Probleme, so dass ich mir nicht erklären kann, wo das
Problem liegt.

Natürlich bin ich kein ARM und GCC Spezialist habe gehofft aber
mit den rudimentären Kenntnissen, die ich besitze, so ein Beispiel
erfolgreich Compilieren zu können.

Ich habe des Projekt aus einer Eclipse Umgebung heruntergeladen
und auf den arm-none-eabi-gcc für cli Ebene angepasst, in der Hoffnung
mit dem 746-Disco spielen zu können.

Scheinbar gestaltet sich das schwieriger als anfangs gedacht.

Hat jemand von Euch noch eine Idee zu dem Thema?

Ja.

Eclipse habe ich nicht Installiert, zumal man da
auch einiges wissen muss um ARM cross compilieren
zu können.

Ich bin mehr für Editor + CLI.

In die jeweiligen IDE's muss man sich auch erst
einarbeiten und versteht nicht immer was intern
beim Build vor sich geht.

Ist schon kompliziert genug die richtigen Compiler
und Linker Parameter herauszufinden.

Wie gesagt ich bin kein professioneller ARM Programmierer
und betreibe diese Dinge mehr als Hobby und um die
Technik besser begreifen zu können, die sich dahinter
verbirgt.

Mach mal einen Clean-Build und dann einen "find ." und stell das hier 
rein.

P.S. Lass Dich nicht verwirren, auch ohne Eclipse kann man arbeiten (VI 
und Makefile) :-)

Hallo Daniel,
hallo hp-freund,


anbei der gewünschte Output als Anhang.

ich habe im Makefile (Makefile.mw), dass ich mit -f
an make übergebe, extra die ECHO Sequenz

$(ECHO) "  $(CXX) $(LDFLAGS) -TSystem/STM32F746NGHx_FLASH.ld -Xlinker 
--gc-sections -Llibs -Wl,-Map,${LPRJ}.map -o ${LPRJ}.elf $(OBJS) $(LIBS) 
System/startup_stm32f746xx.o"

eingebaut um zu sehen was make macht und um den Aufruf
manuell an die Kommandozeile übergeben zu können.

$(CXX) $(LDFLAGS) -TSystem/STM32F746NGHx_FLASH.ld -Xlinker --gc-sections 
-Llibs -Wl,-Map,${LPRJ}.map -o ${LPRJ}.elf $(OBJS) $(LIBS) 
System/startup_stm32f746xx.o

Leider hat mir das noch nicht den Fehler gezeigt.

Den Teil "System/startup_stm32f746xx.o" Habe ich händisch hinzugefügt,
um den Startcode aus dem startup_stm32f746xx.s File als Object-File dem
Linker zu übergeben.

Was mich noch etwas verwirrt, ist das der arm-none-eabi-g++ und nicht
der arm-none-eabi-ld zum Linken verwendet wird.

Das Makefile ist nicht mein eigenes, wurde aber von mir für meine
ersten Versuche übernommen und angepasst.

Möglicherweise steckt da noch ein logischer Fehler drin.
Syntaktisch scheint es ok zu sein.

Danke für Deine und Eure Mühe.

Hi,

keine Ahnung, habe nur die c,h,s Files aus dem Projekt
übernommen und in meine Verzeichnisstruktur eingebettet.

Der Linker mosert noch an weiteren Stellen, nicht nur wegen
audio_play.c

siehe Output:

Markus

PS.: habe mal die main.c und main.h aus dem Beispiel dran gehängt,
Vielleicht hilft das.

Hallo Holger,

jetzt hat es klick gemacht,

ich habe alle Projektbezogenen .c und .h Dateien
im mein Hauptverzeichnis kopiert aber die Verzeichnisse
Src und Inc weiterhin im Hauptverzeichnis belassen, so
dass die main.c zweimal vorhanden ist.

Manchmal sieht man vor lauter Bäumen den Wald nicht mehr.
Mia Culpa!

Werde dass sofort anpassen und Scr und Inc aus dem Ordner
entfernen.

Danke dass Du mir die Augen geöffnet hast.

Hallo

Nach der Bereinigung des Project-Hauptverzeichnisses
bekomme ich leider immer noch Meldungen zu Mehrfach-
definitionen von Symbolen.

Muss noch genauer Suchen, nicht dass ich noch so einen
Schnitzer irgendwo habe. Sorry!

Hallo Holger,

Congratulations

Volltreffer.

Bin gespannt, ob nach dem Flashen was am Display zu sehen ist.

Herzlichen Dank an alle Beteiligten für Ihre Hilfe und Mühe.

Bis zum nächsten Problem ;-)

Hallo

zur Info,

das flashen der .bin Datei an Adr. 0x08000000
