"""Zephyr flash/debug script
|
|
|
|
This helper script is the build system's entry point to Zephyr's
|
|
"runner" Python package. This package provides ZephyrBinaryRunner,
|
|
which is a standard interface for flashing and debugging boards
|
|
supported by Zephyr, as well as backend-specific scripts for tools
|
|
such as OpenOCD, pyOCD, etc.

|
|
# python zephyr_flash_debug.py openocd --openocd-bin=/openocd/path ...
|
|
#
|
|
# For now, maintain compatibility.
