"""Flash an EFR32 device.
This is layered so that a caller can perform individual operations
through an `Flasher` instance, or operations according to a command line.
For `Flasher`, see the class documentation. For the parse_command()
interface or standalone execution:
usage: efr32_firmware_utils.py [-h] [--verbose] [--erase] [--application FILE]
[--verify_application] [--reset] [--skip_reset]
[--commander FILE] [--device DEVICE]
[--serialno SERIAL] [--ip ADDRESS]
Flash EFR32 device
optional arguments:
-h, --help show this help message and exit
configuration:
--verbose, -v Report more verbosely
--commander FILE File name of the commander executable
--device DEVICE, -d DEVICE
Device family or platform to target
--serialno SERIAL, -s SERIAL
Serial number of device to flash
--ip ADDRESS, -a ADDRESS
Ip Address of the targeted flasher
operations:
--erase Erase device
--application FILE Flash an image
--verify_application, --verify-application
Verify the image after flashing
--reset Reset device after flashing
--skip_reset, --skip-reset
Do not reset device after flashing
