@jkandasa Thank you for your help: I summarize what you asked me to do and which works now:
The (minimum) equipment to test FOTA: I have a ATMega 328p BareBones (8MHz internal) + led attached to PB1 (pin15)+ SPI Flash memory + 3.3v regulator + RFM69HCW.
This is the first sketch to upload one time with the USB to FTDI connector :
//pr1: minimal sketch for fota with blink led #define blinkTime 200 #define SKETCH_NAME "SensBender Led 200 -70" //25 caracteres max #define SKETCH_VERSION "pr1" //===== RFM config ===== // Enable and select radio type attached #define MY_RADIO_RFM69 //#define MY_DEBUG_VERBOSE_RFM69 //#define MY_DEBUG_VERBOSE_RFM69_REGISTERS #define MY_RFM69_NEW_DRIVER //#define MY_RFM69_ATC_MODE_DISABLED #define MY_RFM69_ATC_TARGET_RSSI_DBM (-70) // target RSSI -70dBm//BUG //#define MY_RFM69_MAX_POWER_LEVEL_DBM (20) // max.

Enjoy
