Preventing cross-gdb/insight download of specific sections?

[Toralf Lund <toralf at procaptura dot com>]

Somewhat off-topic, but...

Does anyone know how I can skip specific sections from the insight/gdb 
download to my board, or alternatively, leave them out from the binary 
file (without getting unresolved symbols)?

The ld manual says

   The special output section name `/DISCARD/' may be used to discard
   input sections.  Any input sections which are assigned to an output
   section named `/DISCARD/' are not included in the output file.

So I tried
 .fpga :
 {
   . += 1;
   . = ALIGN(64K);    /* We may assume vector section <64K */
   xc2*.o*(.data*)
   . = ALIGN(64K);    /* Let (load addr of) next section be nicely 
aligned */
 }  > flash AT > /DISCARD/

and also just
  } > /DISCARD/
at the last line

(.fpga is the section I wan to leave out) but got

/usr/arm-coff/bin/ld: section .fpga [00000000 -> 0002ffff] overlaps 
section .dbgvect [00000000 -> 00000023]

(where .dbgvect is a section starting at address 0 which I do wand.)

Also, I tried assigning an address to /DISCARD/ (even though this didn't 
seem right), but then the linker would happily include it, and the 
debugger download it.

Help, anyone?
