Flashing
|
|
========
|
|
|
|
The flash on board is not supported by Zephyr at this time.
|
|
Board is booted over PCIe interface.
|
|
|
|
Debugging
|
|
=========
|
|
The bcm958402m2_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.
