Hallo Leute,
das mit den Blöcken funktioniert. Laut .map File packt er jetzt die read
only blöcke vor die den definierten Speicherblock (.rodata in FLASH). Er
teilt also .text nicht wie ich es erwartet habe. Ich denke der ld kann
das nicht wie ihr bereits gesagt habt.
Auf die Gefahr hin das mein ld script zerfezt wird... habt ihr
Anregungen?
