| 28 | |
| 29 | 2. Memory Map |
| 30 | |
| 31 | 2.1. The memory map should look pretty much like this: |
| 32 | |
| 33 | 0x0000_0000 0x7fff_ffff DDR 2G |
| 34 | 0x8000_0000 0x9fff_ffff PCI MEM 512M |
| 35 | 0xc000_0000 0xdfff_ffff Rapid IO 512M |
| 36 | 0xe000_0000 0xe00f_ffff CCSR 1M |
| 37 | 0xe200_0000 0xe2ff_ffff PCI IO 16M |
| 38 | 0xf000_0000 0xf7ff_ffff SDRAM 128M |
| 39 | 0xf800_0000 0xf80f_ffff BCSR 1M |
| 40 | 0xfe00_0000 0xffff_ffff FLASH (boot bank) 16M |

| 43 | 3. Definitions |
| 44 | |
| 45 | 3.1 Explanation of NEW definitions in: |
| 46 | |
| 47 | include/configs/MPC8349ADS.h |
| 48 | |
| 49 | CONFIG_MPC83xx MPC83xx family |
| 50 | CONFIG_MPC8349 MPC8349 specific |
| 51 | CONFIG_MPC8349ADS MPC8349ADS board specific |
| 52 | CONFIG_TSEC_ENET Use on-chip 10/100/1000 ethernet |
| 53 | |
| 54 | |
| 55 | 4. Compilation |
| 56 | |
| 57 | Assuming you're using BASH shell: |
| 58 | |
| 59 | export CROSS_COMPILE=your-cross-compile-prefix |
| 60 | cd u-boot |
| 61 | make distclean |
| 62 | make MPC8349ADS_config |
| 63 | make |
| 64 | |
| 65 | 5. Downloading and Flashing Images |
| 66 | |
| 67 | 5.0 Download over serial line using Kermit: |
| 68 | |
| 69 | loadb |
| 70 | [Drop to kermit: |
| 71 | ^\c |
| 72 | send <u-boot-bin-image> |
| 73 | c |
| 74 | ] |
| 75 | |
| 76 | |
| 77 | Or via tftp: |
| 78 | |
| 79 | tftp 10000 u-boot.bin |
| 80 | |
| 81 | 5.1 Reflash U-boot Image using U-boot |
| 82 | |
| 83 | tftp 10000 u-boot.bin |
| 84 | protect off fe000000 fe09ffff |
| 85 | erase fe000000 fe09ffff |
| 86 | |
| 87 | cp.b 10000 fe000000 xxxx |
| 88 | or |
| 89 | cp.b 10000 fe000000 a0000 |
| 90 | |
| 91 | You might have to supply the correct byte count for 'xxxx' from |
| 92 | the TFTP. Maybe a0000 will work too, that corresponds to the |
| 93 | erased sectors. |
