| 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. | |
