1 | Freescale MPC837xEMDS Board |
2 | ----------------------------------------- | |
3 | 1. Board Switches and Jumpers | |
53677ef1 | 4 | 1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC837xEMDS board |
f8900ce9 DL |
5 | For some reason, the HW designers describe the switch settings |
6 | in terms of 0 and 1, and then map that to physical switches where | |
7 | the label "On" refers to logic 0 and "Off" is logic 1. | |
8 | ||
9 | Switch bits are numbered 1 through, like, 4 6 8 or 10, but the | |
10 | bits may contribute to signals that are numbered based at 0, | |
11 | and some of those signals may be high-bit-number-0 too. Heed | |
12 | well the names and labels and do not get confused. | |
13 | ||
14 | "Off" == 1 | |
15 | "On" == 0 | |
16 | ||
17 | SW4[8] is the bit labled 8 on Switch 4. | |
18 | SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2. | |
19 | SW2[1:8]= 0000_0001 refers to bits labeled 1 through 7 is set as "On" | |
20 | and bits labeled 8 is set as "Off". | |
21 | ||
22 | 1.1 For the MPC837xEMDS Processor Board | |
23 | ||
24 | First, make sure the board default setting is consistent with the | |
25 | document shipped with your board. Then apply the following setting: | |
26 | SW3[1-8]= 0011_0000 (BOOTSEQ, ROMLOC setting) | |
27 | SW4[1-8]= 0000_0110 (core PLL setting) | |
28 | SW5[1-8]= 1001_1000 (system PLL, boot up from low end of flash) | |
29 | SW6[1-8]= 0000_1000 (HRCW is read from NOR FLASH) | |
30 | SW7[1-8]= 0110_1101 (TSEC1/2 interface setting - RGMII) | |
31 | J3 2-3, TSEC1 LVDD1 with 2.5V | |
32 | J6 2-3, TSEC2 LVDD2 with 2.5V | |
33 | J9 2-3, CLKIN from osc on board | |
34 | J10 removed, CS0 connect to NOR flash; when mounted, CS0 connect to NAND | |
35 | J11 removed, Hardware Reset Configuration Word load from FLASH(NOR or NAND) | |
36 | mounted, HRCW load from BCSR. | |

40 | 2. Memory Map | |
41 | ||
42 | 2.1. The memory map should look pretty much like this: | |
43 | ||
44 | 0x0000_0000 0x7fff_ffff DDR 2G | |
45 | 0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M | |
46 | 0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M | |
47 | 0xc000_0000 0xdfff_ffff Empty 512M | |
48 | 0xe000_0000 0xe00f_ffff Int Mem Reg Space 1M | |
49 | 0xe010_0000 0xe02f_ffff Empty 2M | |
50 | 0xe030_0000 0xe03f_ffff PCI IO 1M | |
51 | 0xe040_0000 0xe05f_ffff Empty 2M | |
be5a7190 | 52 | 0xe060_0000 0xe060_7fff NAND Flash 32K |
f8900ce9 DL |
53 | 0xf400_0000 0xf7ff_ffff Empty 64M |
54 | 0xf800_0000 0xf800_7fff BCSR on CS1 32K | |
55 | 0xfe00_0000 0xffff_ffff NOR Flash on CS0 32M | |

59 | 3.1 Explanation of NEW definitions in: | |
60 | ||
61 | include/configs/MPC837XEMDS.h | |
62 | ||
0f898604 | 63 | CONFIG_MPC83xx MPC83xx family for both MPC837x and MPC8360 |
2c7920af | 64 | CONFIG_MPC837x MPC837x specific |

65 | CONFIG_MPC837XEMDS MPC837XEMDS board specific |
66 | ||
67 | 4. Compilation | |
68 | ||
69 | Assuming you're using BASH shell: | |
70 | ||
71 | export CROSS_COMPILE=your-cross-compile-prefix | |
72 | cd u-boot | |
73 | make distclean | |
74 | make MPC837XEMDS_config | |
75 | make | |
76 | ||
77 | 5. Downloading and Flashing Images | |
78 | ||
79 | 5.0 Download over serial line using Kermit: | |
80 | ||
81 | loadb | |
82 | [Drop to kermit: | |
83 | ^\c | |
84 | send <u-boot-bin-image> | |
85 | c | |
86 | ] | |
87 | ||
88 | ||
89 | Or via tftp: | |
90 | ||
91 | tftp 40000 u-boot.bin | |
92 | ||
93 | 5.1 Reflash U-boot Image using U-boot | |
94 | ||
95 | tftp 40000 u-boot.bin | |
96 | protect off fe000000 fe1fffff | |
97 | erase fe000000 fe1fffff | |
98 | ||
99 | cp.b 40000 fe000000 xxxx | |
100 | ||
101 | You have to supply the correct byte count with 'xxxx' from the TFTP result log. | |
102 | ||
103 | 6. Notes | |
104 | 1) The console baudrate for MPC837XEMDS is 115200bps. |
