I will come back to this when trying again with sdk 1.0.1.

- Sat Jun 06, 2015 2:34 pm #19675 I'm using 1.1.0 and I didn't see any real issues. Had to change/delete some #defines that I wasn't using anyway (http://bbs.espressif.com/viewtopic.php?f=7&t=483).

It creates a non-working code :lol:

@cal
SDK uses a different library libgcc.a. The ROM-BIOS code from the old library and libgcc.a another compiler. The combination is not 100%.
My version cropped libgcc tested to use the current version of SDK and configuration gcc...
