Noob here:

Trying to update the firmware to this download from electrodragon - http://www.electrodragon.com/w/Wi07c#Updates .

I have a mac and am connected successfully through a FTDI and am running AT commands successfully on my serial port /dev/cu.usbserial-A7....

The utilities seem pretty easy for Windows environment, but I'm trying to accomplish this on the mac.

I see some people mentioning esptool.py -

I have the script, but I've downloaded nothing else to go with it.

Are there any tutorials or any other resources anyone could point me to to update the firmware on my ESP8266 via a mac?

Thanks so much in advance!

Below the command and (some) output of flashing the 1st .bin on my Mac:

Code: Select allMac-mini-van-gerard:Documents gerard$ sudo ./esptool.py --port /dev/cu.usbserial-A4004QZw write_flash 0x00000 0x00000.bin

Writing at 0x00008400... (97 %)

Good luck!

Thanks for the reply.

When you mention 'ESP-1' from electrodragon, what are you referring to?

Their version of the esptool.py? ( Do you have a link?)

Oh, you meant the hardware version. Right on. Thanks, I'll give this a go and report back.
