Cannot create serial connection on OS X

Hi guys,

I have a trouble connecting Edison with Mac via serial, thus can't configure WiFi.

- Edison plugged with 2 micro-USB cables to 2 macbook USB ports;

- macbook is on power;

- went through all the process and run installer;

- Arduino sketches work fine, blinked led, displayed the text on lcd etc.;

- serial connection does not work

I have already tried multiple cables, restarts etc. Nothing helps.

/dev/cu.usbserial-A903KYQX simply does not appear.

FTDI 2.3 driver installed.

Here is debugging information from my mac:

Network:

FT232R USB UART:

Type: PPP (PPPSerial)

Hardware: Modem

BSD Device Name: usbserial-A903KYQX

IPv4:

Configuration Method: PPP

IPv6:

Configuration Method: Automatic

Proxies:

FTP Passive Mode: Yes

Service Order: 0

Edison:

Type: Ethernet

Hardware: Ethernet

BSD Device Name: en5

IPv4 Addresses: 169.254.147.93

IPv4:

+-o Root Hub Simulation Simulation@14000000

+-o BRCM20702 Hub@14300000

| | "PortNum" = 3

| +-o Bluetooth USB Host Controller@14330000

| "PortNum" = 3

+-o Apple Internal Keyboard / Trackpad@14400000

+-o Edison@14100000

"PortNum" = 1

"USB Serial Number" = "3cca452e3a37408364e0564a72026ded"

Does anyone know what's wrong with the serial connection?

Hi weberx,

Have you been able flash the board?

Which OS X are you using?

Did you download the driver from http://www.ftdichip.com/Drivers/VCP.htm Virtual COM Port Drivers?

What is the output on the Serial Monitor after uploading the following sketch with the Arduino IDE?

void setup() {

system("configure_edison --version > /dev/ttyGS0");

system("uname -a > /dev/ttyGS0");

}

void loop() {

}

Could you attach a screenshot of what you get after running ls /dev on your Mac with both USB ports connected to the computer?

Which expansion board are you using?

Regards,

Charlie

Charlie, thanks for the answer.

OS X 10.11.2, Arduino breakboard. Edison was flashed through the official Installer from Intel. Anyway, to re-flash you need serial, right?

 

I have finally made it, probably, I was tired the last night

/dev/cu.usbserial-A903KYQX appeared in my system.

The problem was USB cable from Beats Audio headphones does not work with Edison, neither for power (despite the led is on) nor for serial connection.

Simply took another one.

ioreg -p IOUSB -l -b | grep -E "@|PortNum|USB Serial Number"

+-o Edison@14200000

| "PortNum" = 2

| "USB Serial Number" = "3cca452e3a37408364e0564a72026ded"

+-o FT232R USB UART@14100000

"PortNum" = 1

"USB Serial Number" = "A903KYQX"
