- Thu Oct 13, 2016 8:02 pm #56485 I installe it 4 times.
Everytime, it works fine for 2 or 3 times, but it crashes (the eclipse crashes and becam unresponsive).
After that, I have to force close the eclipse and, after that, the eclipse crashes at the befinning (when it asks for the workspace).
In those casas I have to completely remove eclipse and reinstall everything.

Any ideas?

Thanks

Hi !!

I just try to open new project , when I follow this tutorial I have the following output

Code: Select allmingw32-make.exe -f C:/Users/user/workspace/esp8266-test2/Makefile all
AR build/app_app.a

I could not find the solution ? What is my possible mistake ?
By the way, all other projects works well..
Can you help me ?

Thanks..

you need to create a user_main.c containing these two functions. An example of user_rf_cal_sector_set can be found in the esp-open-sdk or in CHERTS dev kit examples. Same with user_init.

If you already have user_main.c with these functions then maybe it's not included in the link list?

- Fri Nov 25, 2016 2:54 am #58646 Did anyone fix the problem that the esp8266 just prints a lot of exception on the console if the program was compiled and flashed with the SDK >= 2.0? My controller doesn't do what it is supposed to do it just prints a lot of fatal exceptions. Does anyone know how to fix this?
