hi
i just reinstalled my mac system because of a damn broken disk
and now i was installing esp-nodemcu stuff for arduino.
installed the chip driver and everything as i did before
but now when i try to flash the esp the process is stuck
and i can't actually even kill it.

if i check with the terminal i see this process:
/Users/komarek/Library/Arduino15/packages/esp8266/tools/esptool/0.4.9/esptool -cd nodemcu -cb 115200 -cp /dev/cu.SLAB_USBtoUART -ca 0x00000 -cf /var/folders/vz/qxry2ffs3rnd2xtd557pgcf00000gp/T/arduino_build_192633/Blink.ino.bin

which is goin on forever.
sudo kill doesnt work
and even rebooting the mac is a problem...

is there anything you suggest?

i am obviously using the last Arduino IDE on a Mac os x Sierra

cheers

i also try with esptool.py
with this line:
esptool.py --port /dev/tty.SLAB_USBtoUART write_flash 0x00000 /var/folders/vz/qxry2ffs3rnd2xtd557pgcf00000gp/T/arduino_build_657411/Blink.ino.bin 0x40000 /var/folders/vz/qxry2ffs3rnd2xtd557pgcf00000gp/T/arduino_build_657411/Blink.ino.bin

but it keeps "connecting..." forever

then i can't even stop the process

ok nobody answered.
anyway
i installed another version of the driver from silabs website and now it's working

Sorry about that, but I'm affraid the percentage of Mac OSX users is a lot less than Linux and Windows users.

But... a good thing you solved it (and thanks for posting the solution here).
