upload problem encountered in Arduino IDE
Here's the end of trying to build WiFiScan example using the 1.6.4-673-g8cd3697 board definition:

I tried various combinations of flags -bf, -bm and -cb to no avail.
But esptool.py uploads fine:

Setup:
- esptool v0.4.4
- ESP-01
- PL-2303HX USB-to-serial adapter like this
- Mac OS 10.10.3
- pretty sure I'm using the FTDI v2.3 driver as found here but I don't know how to determine that.

Wow, looks like a bug. Will check.
Side note: since you are using a PL2303-based USB-serial converter, the version of FTDI driver is kind of irrelevant.
Investigated this a bit. Totally weird. The issue comes from the fact that the reply packet has incorrect size or checksum. I tried to print out each received byte:

Here the checksum is already broken (on other runs size was broken as well).
Now when I connect a scope, I see the ESP is sending the correct data:
But the bytes I read from the port are different. Looking further.
Hi, I had same problem on Mac OS X Yosemite 10.10.3 and it is fixed by esptool.py. Short tutorial for switching uploader from esptool to esptool.py on Mac
http://hpclab.blogspot.com/2015/06/esp8266-arduino-ide-on-mac-os-x.html
Hope it would help someone who just jumped into ESP8266 world
It might be worthwhile adding a note to the README, since PL230x based adapters are quite widespread.
FWIW I've since found the CP2102 devices are the most reliable when working with ESP8266's
Hello gentlemen, I was having constantly the same issue with lolin nodemcu 1.0 HW that uses CH340 chip.
I apply the following workaround : http://arduino.stackexchange.com/questions/20219/upload-with-esptool-fails-with-espcomm-send-command-cant-receive-slip-payload installing the esptool.py that works fine for me. (file is platform.txt instead of hardware.txt described)
so... practically .... attached the files that works for me now : (Arduino 1.6.8 / ESP8266 2.20 / OS X 10.11.4 )
platform.txt location >> ~/Library/Arduino15/packages/esp8266/hardware/esp8266/2.2.0 esptool.py.zip location >>~/Library/Arduino15/packages/esp8266/hardware/esp8266/2.2.0/tools (IDE to be restarted)
Dear Ivan, why not considering including this in the official package for Mac with an instruction somewhere ?
I attempted the update above from @etiquet on 2.3.0 with no luck, error being "Failed to connect to ESP8266". Note I kept GPIO 0 low via 10K ohm resistor when plugging board in using a common programmer (http://samy.pl/o/espp.jpg). I've tried both esptool 1.1 and 1.2-dev.
Same when attempting from console:
$ sudo esptool.py --port /dev/cu.Repleo-CH341-00005014 write_flash 0x00000 build5f5ea63a04bf75fd9ebf7eb6ec082a45.tmp/Blink.ino.bin
esptool.py v1.2-dev
Connecting...
A fatal error occurred: Failed to connect to ESP8266
Try to connect The GPIO0 with a 10k resistor to ground and the CH_PD to VCC and it works :)
