i'm not sure, i should post in this section... I'm new in ESP module.

I explain my problem :

I've got a ESP07 module which works fine with AT firmware. I could join AP et get ip nicely.
So i decided to upload my arduino sketch to the module. My first problem was to choose right parameters in the IDE. For the moment, i use 2.2.0 stable version of SDK (in board manager).
I use generic ESP8266 (40Mhz, DIO).
I get two different results :
- with 4M Flash parameter, the module boots and stop on ets_main.c
- with 512K (64K) parameter, the module boots in loop

I should reflash an AT Firmware to get a working module each time. I use this :

Code: Select all2nd boot version : 1.5
  SPI Speed      : 40MHz
  SPI Mode       : DIO
  SPI Flash Size & Map: 8Mbit(512KB+512KB)
jump to run user1 @ 1000

AT version:1.1.0.0(May 11 2016 18:09:56)
SDK version:1.5.4(baaeaebb)
compile time:May 20 2016 15:06:44



I know the sketch works fine because of other users returns but, i could not manage how to correctly put it on the module.
Any idea to help me ?
Thanks in advance

Seb

quick reply :
param IDE : DIO, 40Mhz, 80Mhz, 1M(512+512)
I should remove the Rst pin of the FTDI module and all is fine.
