STM32L151CCT6 Em::Blocks Linker Script
von SK (Gast)

Lesenswert?

Ich benutze Em::Blocks als IDE und möchte einen Quellcode für 
STM32L151CCT6 erstellen. Beim Assistenten für neue Projekte habe ich 
STM32L1xx als Vorlage ausgewählt und ein leeres Projekt erzeugt.
Mir ist jedoch aufgefallen das der Speicher nicht korrekt ist:

STM32L151CCT6
Flash = 256 KB
RAM = 32 KB
EEPROM = 8 KB
Bakeup Register = 128 bytes

Ich denke mal ich müßte jetzt das/die Linker-Scripts anpassen, habe ich 
aber noch nie machen müssen und bin mir deshalb nicht ganz sicher wo ich 
was eintragen muss. Es gibt zwei *.ld Dateien im Projektordner.

Kann mir da jemand weiterhelfen, und mir sagen wo ich da die Speicher 
Größen eintragen muss?

@Bayer
Nee das ist nicht offensichtlich.
Erwarten würde ich hier FLASH RAM, aber es gibt ROM RAM und für den 
EEPROM Speicher gibt es gar keine Section.

Die Startadressen sind immer gleich, die Groesse von rom/ram kannst du

@cs
Danke für die Informationen, es läst sich so schon mal compilieren.
ich habe das wie folgt geändert:

1
/* Memory Spaces Definitions */

2
MEMORY

3
{

4
    ROM  (rx) : ORIGIN = 0x08000000, LENGTH = 256K

5
    RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 32K

6
}
