Hi everybody!
I have a problem with my ESP8266 (ESP-03).
I have followed the instructions to install the virtual machine enviroment(http://www.mikrocontroller.net/attachment/240985/ESP8266_Build_Environment_Guide.pdf). I have used the esp_iot_sdk_1.1.2(http://bbs.espressif.com/download/file.php?id=521) and tried with IoT_Demo example and at example too.
After I get the binaries (eagle.flash.bin and eagle.irom0text.bin) I download them to the esp8266 with esptool.py(eagle.flash.bin to 0x00000 and eagle.irom0text.bin to 0x40000). I have used esptool because I'm using linux.
Everything went without errors, after that I put the esp8266 in normal mode again(disconnect GPIO0) and I restarted it. The problem is that nothing happens now.
I know that the ESP8266 is not broken because if I download to it another firmware (https://github.com/espressif/esp8266_at) with the esptool it works as expected.
Does anyone know what could be happening?
Thanks.

You could try putting GPIO0 high on reboot . Sounds like it may be the watch dog timer reseting repeatedly . Maybe some Serial.println() commands to get a terminal showing serial output might give you a clue.
