can't make a serial connection

Jump to solution

On my linux machine when I type

"sudo screen /dev/ttyUSB0 115200"

to make a connection it asks for my sudo password which I enter and get a blank screen with a flashing cursor then when I press enter twice nothing happens. How do I make it go to the login prompt?

Hi,

Thanks for the advice. Turns out the chip wasn't actually connected to the board all the way, haha. The flashall script you linked me to above helped me out as well with another problem I was having. Thanks for that!

Cheers!

The first question I will ask is if you are sure you have the cable connected to the proper micro-usb connector.

I am going to make some the assumption you are using the Arduino Breakout with the Edison.

Please review the photo here. It shows the proper spot to use for the Serial Console.

Hi,

I had many weird issues when I started because I used poor quality cables or cables that were not true USB but just power cables. Try to use the best cables you may find.

Hi,

 

 

I've seen problems related to the USB ports and cables too. Please try using different cables, USB ports and check that there isn't another process using the same device.

 

If you still have problems after this, please let us know the OS you are using. The problem also could be related to the dfu-util version the PC has.

 

 

Regards,

Hi,

 

 

I would like to know if you have been able to stablish a serial connection with your board. Have you tried with some of our suggestions above?

Sorry about the delay, was out of town this past week. Yes I have the Arduino Breakout with the Edison. I'm pretty sure the cables are fine. They are the originals that came with the module and I've used them before on another Intel Edison in the past and they worked just fine on my linux machine. I'm trying to get it up and running on Windows 10, but I'm having the same problem on my linux machine as well.

Hi,

 

 

I would like to know which is the behavior you have on Windows:

 

1. Are you able to see both ports on the PC?

 

2. How are you powering the board? (USB or Power Supply)

 

3. If you are using a power supply, which are the voltage and current specifications of it?

 

4. Are you using PCs or VMs?

 

5. Which process did you use to flash the board? Did you try with the flashall script? https://communities.intel.com/docs/DOC-25154 https://communities.intel.com/docs/DOC-25154

 

 

Regards,

 

Charlie
