I have not been able to reproduce this. What version of OS X was this on?

rei-vilo commented 9 years ago

Mac OS X 10.10.4 and 10.10.5.

Occurs even after a clean install of Mac OS X 10.10.5, Energia 16 and drivers.

robertinant commented 9 years ago

Thanks! Will try to reproduce.

Occurs when the CC3200 is printing on the Serial port.

On Terminal mode, performing a CRTL-A CTRL-K to close the connection with the Serial port mitigates the issue.

Looks like reminiscent of the same issue with the MSP430G2: I guess another issue with the USB drivers on Mac OS X.

Let's wait and see what Mac OS X 10.11 El Capitan brings and how it manages this specific point.

I have seen the issue just now. And indeed, keyboard / mouse freeze when the CC3200 is unplugged when the Serial port is open. It seems that this is not a Serial driver (FTDI Driver issue). I just saw that when it freezes the kernel reports a USB <-> JTAG/SWD terminate timeout. JTAG uses HID and hence the timeout error seems to be the cause of the keyboard/mouse freeze. I will report to TI XDS110 maintainers for them to look into.

Seems to have been fixed with Mac OS X 10.11.3, although other issues have appeared with other boards.
