pmem RAM variable access for DSP56800E

rcf — Fri, 10 Feb 2006 05:02:30 GMT

Has anyone been successful implementing the "__pmem" type in CW for the 56F8323 etc?

The linker points out that a 16-bit address is inadequate to reach this memory space. However, selecting "large memory" model causes the linker to flag incompatible MSL C library memory model...

for example, "__pmem unsigned int tbuf[buf_size] ;

...

and linker command file including:

.pRAM:

{

* (.bss.pmem)

} > p.internal_RAM

(I am not using PE)

Any help will be much appreciated.

Thanks for listening

update from my original post...

I found under "Using MSL for DSP56800E" in online CW help the reference to the "lmm" options of the MSL C and runtime .lib files.

Now that I have pulled them into the project in the place of the "smm" versions, the linker seems satisfied.

Hope this is helpful to anyone else considering using the __pmem option.
