If you want to use /DISCARD/, you need an output section named /DISCARD/, then put the input sections you want to exclude in there: /DISCARD/ : { *(.section1-to-exclude) *(.section2-to-exclude) } Looks like you are trying to stuff the output section .fpga into a memory region named /DISCARD/. That won't do what you want. With best regards, MKE > The easiest way is to use objcopy to strip off the sections you don't > want.
