The ram memory is full is there a way to deallocate it?

Markus,
Can you attach the .cmd file you are using, just so I can make sure the assignments?  In the out of box .cmd file in C2000Ware it looks like RAML3 is assigned to data space, but never used.  You could try mapping your .ebss/,esysmem to RAML3 vs RAML2.  Or if we need we can bunch L2/L3 into one assignable region if we need all of it for your data vars.

Best,
Matthew

Hello Matthew,

this is my CMD file i use flash nonBIOS cmd

Ty Matthew,

that helped a lot, now i have 2048 bytes instead of 1024.

where did you find these commands to modify this script. sorry I'm still very new to TI controllers.
