| 1. SWITCH SETTINGS |
| ================== |
| 1.1 SW1: 0 - Boot from Socket Flash (AMD) or 1 - Onboard Flash (INTEL) |
| SW2: 0 - Select MPC8220 UART or 1 - Debug Card UART |
| SW3: unsed |
| SW4: 0 - 1284 or 1 - FEC1 |
| SW5: 0 - PEV or 1 - FEC2 |
| |
| |
| 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL |
| =========================================== |
| 2.1. For the initial bringup, we adopted a consistent memory scheme between u-boot and |
| linux kernel, you can customize it based on your system requirements: |
| DDR: 0x00000000-0x1fffffff (max 512MB) |
| MBAR: 0xf0000000-0xf0027fff (128KB) |
| CPLD: 0xf1000000-0xf103ffff (256KB) |
| FPGA: 0xf2000000-0xf203ffff (256KB) |
| Flash: 0xfe000000-0xffffffff (max 32MB) |
| |
| 3. DEFINITIONS AND COMPILATION |
| ============================== |
| 3.1 Explanation on NEW definitions in include/configs/alaska8220.h |
| CONFIG_MPC8220 MPC8220 specific |
| CONFIG_ALASKA8220 Alaska board specific |
| CONFIG_SYS_MPC8220_CLKIN Define Alaska Input Clock |
| CONFIG_PSC_CONSOLE Enable MPC8220 UART |
| CONFIG_EXTUART_CONSOLE Enable External 16552 UART |
| CONFIG_SYS_AMD_BOOT To determine the u-boot is booted from AMD or Intel |
| CONFIG_SYS_MBAR MBAR base address |
| CONFIG_SYS_DEFAULT_MBAR Reset MBAR base address |
| |
| 3.2 Compilation |
| export CROSS_COMPILE=cross-compile-prefix |
| cd u-boot-1-1-x |
| make distclean |
| make Alaska8220_config |
| make |

| 5. REPROGRAM U-BOOT |
| =================== |
| 5.1 Reprogram u-boot (boot from AMD) |
| 1. Unprotect the boot sector |
| => protect off bank 3 |
| 2. Download new u-boot binary file |
| => tftp 0x10000 u-boot.bin |
| 3. Erase bootsector (max 7 sectors) |
| => erase 0xfff00000 0xfff6ffff |
| 4. Program the u-boot to flash |
| => cp.b 0x10000 0xfff00000 |
| 5. Reset for the new u-boot to take place |
| => reset |
| |
| 5.2 Reprogram u-boot (boot from AMD program at INTEL) |
| 1. Unprotect the boot sector |
| => protect off bank 2 |
| 2. Download new u-boot binary file |
| => tftp 0x10000 u-boot.bin |
| 3. Erase bootsector (max 7 sectors) |
| => erase 0xfef00000 0xfefdffff |
| 4. Program the u-boot to flash |
| => cp.b 0x10000 0xfef00000 |
| 5. Reset for the new u-boot to take place |
| => reset |
| |
| 5.3 Reprogram u-boot (boot from INTEL) |
| 1. Unprotect the boot sector |
| => protect off bank 4 |
| 2. Download new u-boot binary file |
