Has anyone written a guide on how to use gdb with Sming? I thought I saw one but can't find it in the wiki. I found something on the web at https://blog.attachix.com/live-debugging-with-open-source-tools-programming-for-esp8266-part-4/
but that is written for an older version of Sming and does not work for me. I have tried to build libsming with ENABLE_GDB but then any samples (including Basic_Debug) won't run (make flashinit; make flash - wdt reset).
