I have flashed a sketch to the 8266 and now I would like to restore the AT commands to the 8266. Can you tell me the easiest way to do this from Linux?

Thank you!

I downloaded the ESP8266_NONOS_SDK zip file from here http://bbs.espressif.com/download/file.php?id=1690
Then got esptool.py from here https://codeload.github.com/espressif/e ... zip/master

Then:
esptool.py -p /dev/ttyUSB0 -b 115200 write_flash \
0x00000 bin/boot_v1.2.bin \
0x01000 bin/at/512+512/user1.1024.new.2.bin \
0xfc000 bin/esp_init_data_default.bin \
0x7e000 bin/blank.bin \
0xfe000 bin/blank.bin

That worked for me using an ESP-07.
