Problems developing with OM13071 under OSX

bburch — Fri, 24 May 2019 18:56:30 GMT

Hi!

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.

Help please?

Thank you!

Have you tried the following?

sudo ./bin/lpcscrypt -d /dev/tty.usbmodem1452 targetinfo
