I suffer from a bad case of random misfiring synapses!

- Fri Sep 18, 2015 5:31 pm #29393 Are you putting the ESP8266 into flashing mode ? Typically done by grounding GPIO 0 during power up and then trying to load code.

- Sat Sep 19, 2015 1:02 am #29410 yup, as per kolban book.
i'm finding quite a few post now from osx users with this.
going to run up the pi2 and see if that works

Just instally esptool, see it that works.

- Sat Sep 19, 2015 4:14 am #29423 Bit of confusion here not made clear anywhere.
Press rst and GPIO 0, release rst then GPIO 0 to program or leave GPIO0 pulled low?
