Hmm, no explicit information to help you, just a little more input.
We regularly use ld to produce COFF and ELF load files, and frequently
use objcopy to produce S-record files for other tools/utilities. Most

scripts) that need to end up in the S-record file. There isn't anything
special I can think of that we are doing that makes this work.
Any chance that the missing output sections are acquiring the "NOLOAD"
attribute like the .bss section? Such sections don't get into the
