Hello all, I've been following the kolban tutorial to build a development environment(https://www.youtube.com/watch?v=AEWoeL1 ... lTutorials) and everything seems to work ok but when I flash the application the blue LED stay always on and the terminal gave me the following message

Fatal exception (29):
epc1=0x40210cd8, epc2=0x00000000, epc3=0x00000000, excvaddr=0x04000173, depc=0x00000000.

Any ideas on how to solve this?
Also, is it possible to use the same USB for debug ?

After run de xtensa-lx102-elf-objdump -x a.out -d on my application directory
I've checked the line for the epc1 number I've found on my serial port for the assembly instruction that caused the issue. I'm attaching the results to this reply. what is it trying to tell me?

I don't think is a faulty module because he works just fine on the arduino IDE v1.6.8 after flashing the firmware using ESP8266Flasher.

Any tips on how to proceed?
