MAC OSX Yosemite invisible board


I connect my newly bought Hexiwear with the docking station and usb cable to my Mac and turn it on. But it is not discovered in Zerynth Studio.  There is a DAPLink CMSIS-DAP connection in the network panel but it appears as “unconfigured”. Can you help we to get this working?



Hi Ture,

By clicking the ‘info’ button with the device connected to your machine, did you see the serial port field different from None? and disk field?

Can you run from the terminal the following command and post me the results?

ztc device discover
<br>Keep me posted :)


There is only “Nothing to Select” in the target dropdown.
The ztc device discover command in Terminal returns nothing. I get no messages in the console app.
In finder I see a mapped drive DAPLINK containing two files, DETAILS.TXT and MBED.HTM. The DETAILS.TXT file contains the following:

Hi Ture,

Thanks for watching us!!! :smiley:
Unfortunately, I can’t replicate your problem; in our Mac machine, all works well.
Do your machine see the Hexiwear as a mass storage? Do your machine see the serial port exposed by the Hexiwear?
