Programming and Debugging
*************************
Flashing
========
The flash on board is not supported by Zephyr at this time.
Board is booted over PCIe interface.
Debugging
=========
The ``bcm958402m2/bcm58402/a72`` board includes pads for soldering a JTAG connector.
Zephyr applications running on the Cortex-A72 core can also be tested
by observing UART console output.
