[EDIT: 20110530 14:06 CDT - reformat - WDR]

We're working with a Texas TMS320LF28335 DSP (C2000), with the Matlab version below and CodeComposer Studio v4.

The program is written to the Flash but for faster execution we load some functions to the RAM using the RAMFUNCS pragma option. The ramfuncs section is allocated in the RAMM0 section by default. Everything works fine as far as our program fits in that memory section. As it got bigger, we tried to set the ramfuncs section to another memory section through the "Target preferences" GUI, eg. RAML4L7. But the generated .cmd file still shows the RAMM0 section set for the ramfuncs. Every other section (eg. .text, .const, .reset...) can be associated to any place, except for the ramfuncs.

Correcting the .cmd file (RAMM0 --> RAML4L7) our program works fine, but we would like to avoid manual intervention.

Is it a bug, or do we miss something?

Thanks,

Balázs
