I try to flash esphttpd example to my esp board http://myesp8266.blogspot.ro/2015/03/ot ... board.html - and have got an error, see below. Can you advise me what to do to solve this error. Thanks Woody

I did a fresh install of CERTS 2.0.2 toolchain, cleaned the NodeMCU repository, and made a new build, and now it links without an error. Yay!

Maybe some old compilation output was not cleaned up previously, but it' working fine now

I'm in the same situation, Windows toolchain.
I tried to fix it with the following (as: Markus was successful doing this)
grabbed CHERTS devkit updated c:\Espressif,
downloaded Espressif-ESP8266-DevKit-v2.0.2-x861.exe, updated that..

but no joy.

Or is this simply a limitation of the windows toolchain?

section `.text' will not fit in region `iram1_0_seg'
when using CHERTS toolchain on Windows

Thanks for responding. For now I've just dropped the math module like others have.
