Board-bring up is a key activity for new silicon. Firmware and OS
are the first software components run on the reference platforms.
Initial bring-up involves debug of silicon, board and the software.
This presentation details the important parts of firmware (u-boot)
and OS (Linux) porting/bring-up for P4080DS reference platform.
Freescale’s Board Support Package (BSP) provides software that
can be modified to run on the customer development systems.
The talk will drive home the strategies, steps, concepts, and
highlight relevant parts of the code needed most commonly
during this effort.
