I am attempting to establish a newt environment on a MacBook running
Mojave. This is a new computer and only supports usb-c ports. I have
attached a newt nano2 through an adapter to one of these ports.
I have meticulously followed the steps to produce the Blinky app and
associated boot loader. Here is the output from newt target show:
targets/my_blinky_sim
app=apps/blinky
bsp=@apache-mynewt-core/hw/bsp/native
build_profile=debug
targets/rbnano2_blinky
app=apps/blinky
bsp=@apache-mynewt-core/hw/bsp/rb-nano2
build_profile=debug
targets/rbnano2_boot
app=@apache-mynewt-core/apps/boot
bsp=@apache-mynewt-core/hw/bsp/rb-nano2
build_profile=optimized
The targets build successfully but when I attempt to load them I get the
following output:
newt load rbnano2_blinky -v
Loading app image into slot 1
Load command:

I have also tried the steps to remove write protection but without changing
the result. Any ideas on why the attempt to write/erase flash is failing?
It seems clear that I am communicating with the device.
Thanks!
