I compile third_party/lwip myself, and the same problem(segmentled section `.text' will not fit in region `iram1_0_seg') happened, can you explain a little about how to force the lib into flash section.
thx

Is there any chance this process is explained somewhere? What needs to be modified in linker script in order for the library to go to flash.

Thanks

Linking Libraries to Flash ICACHE_FLASH_ATTR

2016-02-12T00:19:13+08:00

Is there any way to link libraries directly to flash? I'm using a couple libraries and going through their source code and adding ICACHE_FLASH_ATTR to every function is a deal breaker. There are a ton of functions. Including these libraries are causing me to get an
xtensa-lx106-elf/bin/ld: .output/eagle/debug/image/eagle.app.v6.out section `.text' will not fit in region `iram1_0_seg' error.

are there any options to link static libs directly to flash?
