ESP8266 is very nice unit, I like it very much. I made some projects, programming with .lua and .ino files, and now I wanted to deel with SDK.
I built toolchain according to:
https://github.com/esp8266/esp8266-wiki/wiki/Toolchain#install-the-xtensa-crosstool-ng-as-local-user
but when I wanted to make a small example project (blinky), I got error:
Error calling xtensa-lx106-elf-readelf, do you have Xtensa toolchain in PATH?
On an other forum I got an advice, I have to run:
PATH=$PWD/builds/xtensa-lx106-elf/bin:$PATH
bu it did not help. Has somebody hier a good idea?
