esptool 0.4.6 updloads something weird, but esptool.py does it fine #24

Hi, I'm facing an strange problem on OSX 10.11. When I upload the firmware to my esp8266 E-12 with esptool 0.4.6, the chip doesn't work fine.

The problem is that I don't know what happens when I upload with esptool. I mean, my device has a multi color led that shows a different color depending on its state. Also prints some traces to the serial port. Well, when I upload with esptool, it doesn't print anything, and the led behaviour is crazy. But I actually don't know what's happening inside the chip.

esptool -vv -cd ck -cb 115200 -cp /dev/cu.usbserial-AL01BY0E -cf firmware.bin

If I upload the same firmware by esptool.py, everything works fine. The command I execute is:

esptool.py --port /dev/cu.usbserial-AL01BY0E write_flash 0x00000 firmware.bin
