ESP8266 Community Forum

Hi, I am using esp-201 module based development board. When I flash any program from the arduino IDE for the ESP8266 it works like charm. But when I use the esp-open-sdk based toolchain , the program is not executing on the esp8266. Instead the LEDs are showing the status as if it is ready to flash. (GPIO12, 13, 14 and 16 are high) and I get junk on the serial terminal. To verify I tried just the bare user_init() function without any statements but with same result. I tried to manually flash the bin files generated by the arduino IDE with the esptool (addresses 0x000000 and 0x0010000 ) and it again works properly. I am using a direct install of Ubuntu 14.04.
Please help. Thanks in advance.
