I am trying to set up a dev environment for OM13071 board under OSX 10.
It enumerates to /dev/tty.usbmodem1452 and a drive named MBED is mounted to the desktop.
When I attempt to communicate, it gives me much the same error each time;
# ./bin/lpcscrypt -d /dev/tty.usbmodem1452 targetinfo
Error opening /dev/tty.usbmodem1452: Resource temporarily unavailable
(Sometimes ISP reset, or erasing the flash, can help...)
Previous error(s) stops further processing
Error: <Command line>:0: Resource temporarily unavailable
Script cmd: batchmode 1
Last target cmd: =print 1713834314
Terminated with errors
The error message says to try reloading the firmware, but that operation fails as well.
I must not be putting it into DFU mode, but I cannot find clear instructions on that, so I might be doing it wrong.
