Yes, I was hoping the linker would first allocate space for absolute-address symbols and then fill the gaps with the remaining symbols in whatever order. > If you read up the binutils doc, you'll see that ld fills output > sections based on a "location pointer" (the "dot") that simply moves > on with each input section added -- no skipping, and no jumping from > one region to another either. I see, thank you for pointing this out. This specific behavior actually seems quite essential to the interpretation of linker scripts, so there is probably no hope for any change there. I very much like your idea of splitting the binary when flashing and recomposing it into RAM during copying just before relocation, it looks very flexible and elegant. A separate solution is still needed for running from flash... apart from switching back to archive libraries and using --whole-archive, I am out of ideas at the moment.
