I've currently got a ram overflow while trying to compile a derivative hack of a Webserver and AT enabled firmware.

Does the xtensa Linker have an option to switch on how much ram I am actually over?

Cheers

Code: Select all/opt/xtensa-lx106-elf/bin/../lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld: .output/eagle/debug/image/eagle.app.v6.out section `.text' will not fit in region `iram1_0_seg'

The closest I can think of is enabling link map dump with -M or -Map=<map-file-name> and looking into it.

I tried that, didn't really work, I upped the iram1_0_seg in the linker file instead until it went away. Looks like I'm 3090bytes over.
