i have connected everything fine i guess.
using a 1000uF capa & a 0,1uF capa between GND & VCC.
i also used 10k resistors to pull up and down.

i managed to upload the WiFiScan example.
but when i lauch in normal mode (GPIO0 to High), i got this message :

When i look at the adress 0x40218354, it seems this is due to a

Code:

user_uart_wait_tx_fifo_empty
!

Can you tell me what i got to do ?
i forgot to mention, i have a IPS 3610D as power supply, configured to provide 3.5v.
my parameters for Arduino IDE are :

Code:

Generic ESP8266 Module
QIO
Flash Frequency 80Mhz
CPU Frequency 80Mhz
Flash size 4MB with 1MB for SPIFFS
debug port : serial
debug level : none
reset method ck
upload speed 115200
programator : AVRIsp mkll (i also tried AVRIsp and USBasp)


This would be important because i want to embed the ESP12e for my clients.
Thank you.
