Arduino IDE: using Linux, OS-X, Win first report and open questions

For a workshop I decided to get 10 ESP8266-EVB-BAT, seeing there is a Arduino-IDE now available.
Also ordered USB-Serial-Cable-F and a power-supply 5V.

So students are good tester falling in every possible trap I want to make just a first small report.
since we used linux-, OS-X and Win? laptops at the course:

A) install procedure indepent of the OS:

Download and install Arduino IDE > 1.6.5:


for Olimex ESP8266 core environment use:

In Arduino IDE under file->preferences URL:

restart Arduino: in Tools->board->Boardmanager install the ESP8266 tools

select Tools->board->Olimex- MODWIFI...

3. Cabling the Serial debugging connection to programm

Connect cable on UEXT-Extension as follows::

    blue --> uext pin-2
    green --> uext pin-3
    red --> ext pin-4

Connect the USB-Serial Cable to your computer, choose the proper serial device unter Tools

4. Compiling, Flashing

Load example Blink and change Pin-number 13 to 5 (which is also the relay).
Compile, Then power on the  ESP8266-EVB-BAT holding button pressed and upload.

after a while the 1 second noise of the relay should be heard.

B) What did not work under the OS

Linux Debian Jessie

Everything worked using the device /dev/ttyUSB0 on my laptop. Be sure to be member of the dialout group.

Mac OS-X

1-2 worked fine.

But the serial cable does not work out of the box under OS-X

Serial Cable-F

It should be named cu.serial under Tools-Port, else there is a need
to install the driver for the Profilic pl2303 for your OS-Version from here:

Compilation worked fine, but upload failed:

FAILED to flash

The esptool for flashing does not work under OS-X. There was blog entry
to exchange it with, so flashing worked but the programm didn't run...

(Any Hint ?)


1-2 worked fine including compiling but serial cable was not recognized out of the box.

Serial Cable-F

Before Installing the driver (if not already installed), unplug device during Installation to prevent to reboot.

Either use the driver mentioned here under Software:



or direct from Chip Vendor of the USB2Serial Chip:


Afterwards the COM3 Port or higher should appear in the Arduino Menu: Tools->Port

Flashing on Windows 7 worked fine.

NOTE: under Windows~8 the serial driver did not WORK ! - Any hint ?


Only with Linux everything worked out of the box. Mac OS-X was not usable and Windows~8 also not with this configuration.

Please help to solve the above, I will update this blog if success.

Goggle for "prolific usb to serial windows code 10" it is the same problem for Windows 8 and Windows 10 - you need an older driver and there is youtube video how switch to it after install
