ESP8266 Community Forum

- Wed Dec 20, 2017 9:06 am #72613 I am trying to create an image of the latest ESP8266_NONOS_SDK.

Flashing with this works fine:

esptool.py --baud 115200 --port /dev/ttyUSB0 write_flash -fm dio -ff 40m -fs detect \
0x00000 /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/boot_v1.7.bin \
0x01000 /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/at/512+512/user1.1024.new.2.bin \
0x81000 /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/at/512+512/user2.1024.new.2.bin \
0x7E000 /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/blank.bin \
0xFC000 /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/esp_init_data_default_v08.bin \
0xFE000 /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/blank.bin

However, when I create an image via:

esptool.py -c esp8266 make_image \
-f /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/boot_v1.7.bin -a 0x00000 \
-f /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/at/512+512/user1.1024.new.2.bin -a 0x01000 \
-f /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/at/512+512/user2.1024.new.2.bin -a 0x81000 \
-f /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/blank.bin -a 0x7E000 \
-f /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/esp_init_data_default_v08.bin -a 0xFC000 \
-f /opt/arduino/esp8266/ESP8266_NONOS_SDK-master/bin/blank.bin -a 0xFE000 \
ESP8266-Master

and try to flash the resultant image with:

esptool.py --baud 115200 --port /dev/ttyUSB0 write_flash -fm dio -ff 40m -fs detect 0x00 ESP8266-Master0x00000.bin

the ESP8266 does not respond.

Anyone know what is wrong with my make_image script?

- Thu Dec 28, 2017 9:44 am #72749 I just found out from the current author/maintainer of esptool.py that it does not support creating a single bin file in that manner.

However, he added that as a future feature.
