1 ---------------------------------------- 2 Booting from On-Chip ROM (eSDHC or eSPI) 3 ---------------------------------------- 4 5 boot_format is a tool to write SD bootable images to a filesystem and build 6 SD/SPI images to a binary file for writing later. 7 8 When booting from an SD card/MMC, boot_format puts the configuration file and 9 the RAM-based U-Boot image on the card. 10 When booting from an EEPROM, boot_format generates a binary image that is used 11 to boot from this EEPROM. 12 13 Where to get boot_format: 14 ======================== 15 16 you can browse it online at: 17 http://git.freescale.com/git/cgit.cgi/ppc/sdk/boot-format.git/ 18 19 Building 20 ======== 21 22 Run the following to build this project 23 24 $ make 25 26 Execution 27 ========= 28 29 boot_format runs under a regular Linux machine and requires a super user mode 30 to run. Execute boot_format as follows. 31 32 For building SD images by writing directly to a file system on SD media: 33 34 $ boot_format $config u-boot.bin -sd $device 35 36 Where $config is the included config.dat file for your platform and $device 37 is the target block device for the SD media on your computer. 38 39 For build binary images directly a local file: 40 41 $ boot_format $config u-boot.bin -spi $file 42 43 Where $file is the target file. Also keep in mind the u-boot.bin file needs 44 to be the u-boot built for your particular platform and target media. 45 46 Example: To generate a u-boot.bin for a P1022DS booting from SD, run the 47 following in the u-boot repository: 48 49 $ make P1022DS_SDCARD 50 51 Configuration Files 52 =================== 53 54 Below are the configuration files to be used with a particular platform. Keep 55 in mind that some of these config files are tied to the platforms DDR speed. 56 Please see the SoC reference manual for more documentation. 57 58 P1022DS config_sram_p1022ds.dat 59 P2020DS config_sram_p2020ds.dat 60 P1020RDB config_ddr2_1g_p1020rdb_533M.dat 61 P1020RDB config_ddr2_1g_p1020rdb_667M.dat 62 P2020RDB config_ddr2_1g_p2020rdb_800M.dat 63 P2020RDB config_ddr2_1g_p2020rdb_667M.dat 64 P2020RDB config_ddr3_1gb_64bit_p2020rdb_pc.dat 65 P1020RDB config_ddr3_1gb_p1_p2_rdb_pc_800M.dat 66 P1011RDB config_ddr3_1gb_p1_p2_rdb_pc_800M.dat 67 P1010RDB config_ddr3_1gb_p1010rdb_800M.dat 68 P1021RDB config_ddr3_1gb_p1_p2_rdb_pc_800M.dat 69 P1022DS config_ddr3_2gb_p1022ds.dat 70 P1024RDB config_ddr3_1gb_p1_p2_rdb_pc_667M.dat 71 P1025RDB config_ddr3_1gb_p1_p2_rdb_pc_667M.dat 72 P1016RDB config_ddr3_1gb_p1_p2_rdb_pc_667M.dat 73 P1020UTM config_ddr3_1gb_p1_p2_rdb_pc_800M.dat 74 P1020MBG config_ddr3_1gb_p1_p2_rdb_pc_800M.dat 75 MPC8536DS config_ddr2_512m_mpc8536ds_667M.dat 76
