Command to merge multiple .bin files into one file for flashing #254
I am trying to create an image of the latest ESP8266_NONOS_SDK for an ESP8266-01 module using the latest esptool.py (v2.2)
Flashing with this works fine:
esptool.py --baud 115200 --port /dev/ttyUSB0 write_flash -fm dio -ff 40m -fs detect
However, when I create an image via:
esptool.py -c esp8266 make_image
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.
Is there something wrong with make_image?
I think there is some confusion over the different kinds of binary images.
Merging multiple binaries into a single file, which can be flashed in one go, is not currently an esptool.py feature. Although I agree it would be good to have. The Windows GUI Flasher Tool can do this.
