Speicheraufteilung TMS320F28335

[Marco (Gast)]

Hallo,
Ich hab noch ein Problem mit meinem DSP TMS320F28335.
Beim linken erscheint die Fehlermeldung

   Use
            -heap option to change the default size.
>>   error: can't allocate .text, size 00009b3f (page 0) in FLASHA (avail:
            00007f80)
>>   error: can't allocate .ebss, size 000011c8 (page 1) in RAML4 (avail:
            00001000)

Die Speicheraufteilung sieht wie folgt aus:

MEMORY
{
PAGE 0:    /* Program Memory */
           /* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE1 for 
data allocation */

   FLASHB      : origin = 0x330000, length = 0x008000     /* on-chip 
FLASH */
}

Kann mir jemand nen Tipp geben, wie ich die Speicheraufteilung 
bearbeiten kann?

Du kannst es doch selbst verändern wie du es brauchst, also statt
   FLASHC: origin = 0x328000, length = 0x008000  /* on-chip FLASH */
   FLASHA: origin = 0x338000, length = 0x007F80  /* on-chip FLASH */

z.B. sowas schreiben
   FLASHA: origin = 0x328000, length = 0x00FF80  /* on-chip FLASH */

Damit sollte es egtl. gehen solange FLASHC nicht irgendwo verändert 
wird, ansonsten kannst du die Bereiche einfach etwas verschieben. Origin 
ist die Startadresse und length die Länge der Sektion.

Danke hat geklappt.

Sollte egtl. verwendet statt verändert heißen, aber da es geklappt 
hat ist das ja egal... ;)
