Adafruit Feather HUZZAH ESP8266 Manual page 53

Whenever I start or reset the ESP8226 there's a bunch of
"gibberish" on the Serial console
This is the ROM debug messages, it's transmitted at 74880 baud so you rarely see
it in proper 'ascii output' - instead usually it gets corrupted into a bunch of strange
characters.
I'm having difficulties uploading to the HUZZAH with the
Arduino IDE
Make sure you're using a good quality USB/Serial cable. Install the official drivers
for that cable too! We've also noticed that PL2303-based cables don't work on
Macs for some reason. FTDI or CP210x based chipsets work best
I tried that, but I'm still having difficulties uploading with
the Arduino IDE
Sometimes, it helps to switch the board type to "Generic ESP8266 Module". Set
the Reset Method to "nodemcu"

I'm stuck in bootloader mode and can't upload
You say your led is stuck on dim and you get an error trying to upload? And you're
sure your serial cable is connected and working correctly? Well, here's a potential
fix: Connect the GPIO0 pin to GND through a 220 ohm resistor. Leave it connected
while you upload. You may have to try it a couple of times, but it should eventually
upload and get the HUZZAH unstuck from bootload mode! You can then remove
the resistor connection, and your HUZZAH will be happy ever after!
(Note: you may also have to tie RST and EN (CH_PD) together to get this to work.
Remove the connection once you have the module programmed).

I can't get Lua to respond to my commands
Make sure your terminal software is sending correct line endings! The default
PuTTY settings may be wrong when trying to talk to Lua on an ESP8266. Lua
expects CRLF "\r\n" line endings, and apparently PuTTY defaults to just LF "\n"!
