that did not work for me. For the hello world sample I see a lot of garbage on the terminal. If I change the baud rate to 78600, this is seen:

Any idea, how to eliminate this issue?

Thanks

Turns out, that the base address of the eagle.irom0text.bin file is set wrong in Makefile.

Should be 40000 and not 10000

ifeq ($(app), 0)
$(ESPTOOL) -p $(ESPPORT) -b $(BAUD) write_flash $(flashimageoptions) 0x00000 $(FW_BASE)/eagle.flash.bin 0x40000 $(FW_BASE)/eagle.irom0text.bin
else
ifeq ($(boot), none)
$(ESPTOOL) -p $(ESPPORT) -b $(BAUD) write_flash $(flashimageoptions) 0x00000 $(FW_BASE)/eagle.flash.bin 0x40000 $(FW_BASE)/eagle.irom0text.bin

I'm using that kit under windows but I should modify a few batch because tools are under a dir named ESP8266
BTW, I need a reference to know what base address to use when using different boards (I have ESP8266-12E 4Mb and ESP8266-100 8Mb).

This is my flashinit segment in the Makefile (address of "esp_init_data_default.bin" already was at 0x3fc000):

flashinit:
$(vecho) "Flash init data:"
$(vecho) "Default config (Clear SDK settings):"
$(vecho) "blank.bin-------->0x3e000"
$(vecho) "blank.bin-------->0x3fc000"
$(vecho) "esp_init_data_default.bin-------->0x3fc000"
$(ESPTOOL) -p $(ESPPORT) write_flash $(flashimageoptions) \
0x3e000 $(SDK_BASE)/bin/blank.bin \
0x3fc000 $(SDK_BASE)/bin/esp_init_data_default.bin \
0x3fe000 $(SDK_BASE)/bin/blank.bin

And this:

SPI_SIZE_MAP ?= 4

Changing the SPI_SIZE_MAP didn't do anything

Take a good look at your code:

$(vecho) "blank.bin-------->0x3fc000"
$(vecho) "esp_init_data_default.bin-------->0x3fc000" - See more at: posting.php?mode=reply&f=9&t=820#sthash.Wb5G7Ltq.dpuf


you are apparently writing both files to same address 0x3fc000.

Try using the addresses I suggested.
