I can't say I have seen this error before but I'll look into it. There's some changes in the pipeline that I'll try to publish soon :)

Exactly the same thing also happens for me. The update always runs smoothly, but I get this error.
Maybe this is related to the fact that I'm using an esp8266EX instead of the non-EX variant?

Oh, you have to write both the .output/eagle/debug/image/eagle.app.v6.flash.bin (dest=0x0) AND the .output/eagle/debug/image/eagle.app.v6.irom0text.bin (dest=0x40000) to the module, then it works fine :)
You might need to reboot the module between the two files.

I can confirm this issue.
Just recently installed the SDK using this tutorial: https://github.com/esp8266/esp8266-wiki/wiki
Within the Makefile the code is as follows:
flash: firmware/0x00000.bin firmware/0x40000.bin
-$(ESPTOOL) --port $(ESPPORT) write_flash 0x00000 firmware/0x00000.bin
sleep 3
-$(ESPTOOL) --port $(ESPPORT) write_flash 0x40000 firmware/0x40000.bin
make flash has the following output (always, not from time to time):
/home/sid/esp8266/esptool/esptool.py --port /dev/ttyUSB0 write_flash 0x00000 firmware/0x00000.bin

It does not seem to leave the flash mode correctly. From that point on, I can not upload code anymore until the next power circle (or reset I suppose).
However, there is a trick: If I manage to do a power circle within the 3 second sleep then the program uploads fine (although the errors appear) and the program works.
Any ideas how I can circumvent this hack?
Note that, I also got the EX version of the chip. And I also tried to upload the original firmware, resulting in the same issue.

i have this exact same problem on a v1 (00160901) board, it was running ok accepting AT commands until i used esptool.py, now it seems stuck in flash mode as it won't accept AT commands and returns gibberish and then "ready" on boot.
power cycling makes no difference and the only way to get to the 2nd flash is to power cycle in the sleep(3) bit, but it still doesn't actually complete:
$ esptool.py --port /dev/ttyUSB0 write_flash 0x00000 firmware/0x00000.bin

Hi,
I forked the project and extended it so that you do not need to power cycle manually. No more reset and bootloader buttons are required. U only need two more wires.
Check it out: https://github.com/3s1d/esp_prog

Put a print statement in the code, and the command(ESPROM.ESP_FLASH_END, ...) method returned:

#5 fixes this properly (based on several independent reports of '\x01\x06' being returned).
