We used to flash the chip with one file (idk 0.9.5 or lua ) .
Today we have tried to flash the new 1.4 sdk from their web site , according to :

(1) blank.bin; to 0x7E000;
(2) eagle.flash.bin, to 0x00000;
(3) eagle.irom0text.bin, to 0x40000;

Using a mac and esptool , we have manage to flash with(they say something about compiling the files?? ) :

sudo ./esptool.py --port /dev/tty.usbmodem1421 write_flash 0x7E000 blank.bin
sudo ./esptool.py --port /dev/tty.usbmodem1421 write_flash 0x00000 eagleflash.bin
sudo ./esptool.py --port /dev/tty.usbmodem1421 write_flash 0x40000 eagleirom0text.bin

where the enable pin is high, and the gpio 0 is on ground.
flashing was good .

Then , using terminal , the chip stopped responding, all we get is garbage on startup(whats the baud rate after flashing??)
We have reseted it multiple times, took out the gpio0 grounded pin ,

What went wrong ?
