Dear All,
First I would like to congratulate and thank the people behind this
fantastic project. I think it is needed and timely.
I have a nordic nrf52480 preview pdk on which I have successfully run
the blinky app and variations of it.
But could not get the bare ble app
(https://mynewt.apache.org/os/tutorials/ble_bare_bones/) to run without
crashing.
The program "crashes" only if both the call to
os_eventq_run(os_eventq_dflt_get()) is made and the following lines:
- "@apache-mynewt-core/net/nimble/controller"
- "@apache-mynewt-core/net/nimble/host"
are present in the pkg.yml file. If these 2 lines AND/OR the
os_eventq_run call are commented out the program does not crash.
Similar problem with the beacon example.
The main function, pkg.yml content, gdb output and gdb server output are
pasted below.
Your help is most appreciated.
