I am use ESP8266-01 wifi module with arduino uno. For while time upload sketch from board manager i was selected Generic ESP8266 Module. But I were get error.
But my main problem is that: While I am select Generic ESP8266 Module from board manager, when I am upload sketch to the board. Where to upload my sketch (means in arduino or esp8266)?
Please help me.

(Software serial, using another two ports to connect the 8266?) or using the D0 & D1 pins? If using the software serial, what sketch are you using? If using the RX/TX ports (D0 & D1) of the uno, are you running the Arduino with the reset tied to GND, or a empty program? (that won't use the Uno's UART).
Other things, is GPIO0 tied low when you try to transfer the 8266's sketch, or floating? and did you toggle the reset (with GPIO0 low, pull RST low, then allow to float) before uploading the 8266's sketch? and, the fun part, at what baud rate? (most firmwares are pre-wired 115200-Baud) I just got mine talking, both firmware upload and the simple Blink sketch, so I'm a bit of a newbie too, just getting my feet wet.
(when I say Floating, either pulled-high with a 10K resistor, or open circuit (nothing connected)
