Hello yingkitw,

 

 

Sometimes OSX machines have issues with the FTDI drivers included in their installation or they don't include it at all. I'd suggest you to follow the guide in: http://www.ftdichip.com/Support/Documents/InstallGuides.htm http://www.ftdichip.com/Support/Documents/InstallGuides.htm to install the FTDI driver on your computer.

 

 

Let me know if it works,

 

Peter.

intel_corp: I can't speak for Ying, but I've started encountering the same problem. A few days ago, I could log into and work on Edison from my laptop (a macbook pro running OS X 10.11.4). Today I can't. I get the same error message:

"The disk you inserted was not readable by this computer."

I've tried a fresh Edison, right out of the package, and started getting this same error message again as soon as it was flashed.

I've been working with MANY different microcontrollers over the last few days, so it's possible one of the others blew up the drivers that the Edison needed.

Since reading this, I've tried installing the FTDI drivers, but found the instructions vague. Could you clarify a bit?

  1. There are two different FTDI drivers: VCP and D2XX. And under 10.11, they're known to step on each others' toes. Which of the two does Edison need?
  2. If the Edison needs the D2XX drivers, which ones do you recommend? I see two to choose from: 10.4 and 10.5-10.7. I'm assuming these refer to the version numbers of OS X they should go with. There doesn't seem to be an option for the current version of OS X, 10.11.
  3. Other than drivers, what else could this be?

Edited to add:

At this moment, I've uninstalled the D2XX driver (and helper) and I can see cu.usbmodemXXXX and cu.usbserial-XXXXXX in the /dev list.

AND HEY, after many reboots, and much poking about, I seem to be able to log into the Edison from the terminal again. I still can't see the Edison as a hard drive, but I can log in again. PROGRESS!

Hello sambrown,

 

 

1. You are correct, you should install the D2XX.

 

2. You should install the one that is found in http://www.ftdichip.com/Drivers/D2XX.htm, it should be compatible with the latest version of OSX.

 

3. Something else that could be happening is that your Edison has a software issue at a low level. In case this was the problem, it should be solved by flashing the Edison with Flash Tool Lite (which can be found in https://software.intel.com/en-us/iot/hardware/edison/downloads) or Flashall (https://communities.intel.com/docs/DOC-25154 https://communities.intel.com/docs/DOC-25154).

 

 

Let me know if this helps.

 

Peter.
