P4080 PCIe Adapter SDK User Guide Production Release

Freescale Semiconductor
File system (used in RAM disk) that contains the needed user space files including
USDPAA
example application binaries. Linux must be booted using this file system.
All six of the files listed above are needed to run USDPAA on the card. The first three must be
programmed into the NOR flash. The last three may be programmed into the NOR flash, but also
may be loaded into RAM by u-boot using the tftp protocol.
U-boot is also capable of loading files into RAM via tftp and then programming them into the
NOR flash. In all cases, you must have access to a tftp server, ideally on your Linux development
host.
Copy the six files listed above to a directory from which they can be accessed via your tftp server.
U-boot on the P4080 PCIE Adapter must use tftp to access them. Details of installing and
configuring a tftp server on your development host are specific to your host Linux distribution.
6.6 Programming P4080 PCIE Adapter NOR Flash Bank 0
The P4080 PCIE Adapter has a feature that uses address swizzling to make it appear that the
NOR flash is divided into multiple parts-- this document will assume two. The parts are called
“bank 0” and “bank 4”.
When you power-on or reset, u-boot will boot from bank 0. U-boot in bank 0 can program
images into bank 4. Then, you can enter “n710_reset altbank” from the bank 0 u-boot prompt
to boot into bank 4.
It is recommended to leave the bank 0 images alone and simply use them to program images into
bank 4. This is to ensure that you always have working images in bank 0. Programming Bank 0
should only be used, once the images have been validated in bank 4.
