Booting from On-Chip ROM (eSDHC or eSPI)
|
|
----------------------------------------
|
|
|
|
boot_format is a tool to write SD bootable images to a filesystem and build
|
|
SD/SPI images to a binary file for writing later.
|
|
|
|
When booting from an SD card/MMC, boot_format puts the configuration file and
|
|
the RAM-based U-Boot image on the card.
|
|
When booting from an EEPROM, boot_format generates a binary image that is used
|
|
to boot from this EEPROM.
|
|
|
|
Where to get boot_format:
|
|
========================
|
|
|
|
you can browse it online at:
|
|
http://git.freescale.com/git/cgit.cgi/ppc/sdk/boot-format.git/
|
|
|
|
Building
|
|
========
|
|
|
|
Run the following to build this project
|
|
|
|
$ make
|
|
|
|
Execution
|
|
=========
|
|
|
|
boot_format runs under a regular Linux machine and requires a super user mode
|
|
to run. Execute boot_format as follows.
|
|
|
|
For building SD images by writing directly to a file system on SD media:
|
|
|
|
$ boot_format $config u-boot.bin -sd $device
|
|
|
|
Where $config is the included config.dat file for your platform and $device
|
|
is the target block device for the SD media on your computer.
|
|
|
|
For build binary images directly a local file:
|
|
|
|
$ boot_format $config u-boot.bin -spi $file
|
|
|
|
Where $file is the target file. Also keep in mind the u-boot.bin file needs
|
|
to be the u-boot built for your particular platform and target media.
|
|
|
|
Example: To generate a u-boot.bin for a P1022DS booting from SD, run the
|
|
following in the u-boot repository:
|
|
|
|
$ make P1022DS_SDCARD
|
|
|
|
Configuration Files
|
|
===================
|
|
|
|
Below are the configuration files to be used with a particular platform. Keep
|
|
in mind that some of these config files are tied to the platforms DDR speed.
|
|
Please see the SoC reference manual for more documentation.
