Memory Allocation Guidelines? (dupe post)

Pardon the duplicate post from the C55xx forum, but it's very quiet over there.....:(

======================================================

Are there published guidelines for where to allocate the various memory sections of the C5515? I am struggling to squeeze all of my code into available memory and specifically wonder if it is OK to put .const and .bss into SARAM? When I do this, things start getting a bit squirrely.

Below is the allocation that worked until my code got too large to fit.

.bss : > DARAM
vectors : > VEC ALIGN = 256
.stack : > DARAM 
.sysstack : > DARAM
.sysmem : > DARAM
.text : > SARAM
.data : > DARAM 
.cinit : > SARAM
.const : > DARAM
.cio : > SARAM
.switch : > DARAM

    The relevant section of the compiler manual is titled Specifying Where to Allocate Sections in Memory.  But I don't think it will help much in this situation.  The compiler doesn't care about the distinction between DARAM and SARAM.  Both kinds of memory can support read and write access.  I suspect that whatever is wrong is related to the hardware, and not the compiler.

    Thanks and regards,

    Thanks George. Turns out an errant interrupt was crashing things.
