The easiest way is to use objcopy to strip off the sections you don't want. Then download the stripped file, but load symbols from the original. -- Richard Sewards -----Original Message----- From: Toralf Lund [mailto:toralf@procaptura.com] Sent: Tuesday, September 21, 2004 4:15 AM To: crossgcc Subject: Preventing cross-gdb/insight download of specific sections? 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.
