2-----------------------------------------
31. Board Switches and Jumpers
41.0 There are five Dual-In-Line Packages(DIP) Switches on MPC832XE SYS board
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 SW3 is switch 18 as silk-screened onto the board.
18 SW4[8] is the bit labled 8 on Switch 4.
19 SW5[1:6] refers to bits labeled 1 through 6 in order on switch 5.
20 SW6[7:1] refers to bits labeled 7 through 1 in order on switch 6.
21 SW7[1:8]= 0000_0001 refers to bits labeled 1 through 6 is set as "On"
22 and bits labeled 8 is set as "Off".

241.1 For the MPC832XEMDS PROTO Board
25
26 First, make sure the board default setting is consistent with the document
27 shipped with your board. Then apply the following setting:
28 SW3[1-8]= 0000_1000 (core PLL setting, core enable)
29 SW4[1-8]= 0001_0010 (Flash boot on local bus, system PLL setting)
30 SW5[1-8]= 0010_0110 (Boot from high end)
31 SW6[1-8]= 0011_0100 (Flash boot on 16 bit local bus)
32 SW7[1-8]= 1000_0011 (QE PLL setting)
33
34 ENET3/4 MII mode settings:
35 J1 1-2 (ETH3_TXER)
36 J2 2-3 (MII mode)
37 J3 2-3 (MII mode)
38 J4 2-3 (ADSL clockOscillator)
39 J5 1-2 (ETH4_TXER)
40 J6 2-3 (ClockOscillator)
41 JP1 removed (don't force PORESET)
42 JP2 mounted (ETH4/2 MII)
43 JP3 mounted (ETH3 MII)
44 JP4 mounted (HRCW from BCSR)
45
46 ENET3/4 RMII mode settings:
47 J1 1-2 (ETH3_TXER)
48 J2 1-2 (RMII mode)
49 J3 1-2 (RMII mode)
50 J4 2-3 (ADSL clockOscillator)
51 J5 1-2 (ETH4_TXER)
52 J6 2-3 (ClockOscillator)
53 JP1 removed (don't force PORESET)
54 JP2 removed (ETH4/2 RMII)
55 JP3 removed (ETH3 RMII)
56 JP4 removed (HRCW from FLASH)

632.1 The memory map should look pretty much like this:
64
65 0x0000_0000 0x7fff_ffff DDR 2G
66 0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M
67 0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M
68 0xc000_0000 0xdfff_ffff Empty 512M
69 0xe000_0000 0xe01f_ffff Int Mem Reg Space 2M
70 0xe020_0000 0xe02f_ffff Empty 1M
71 0xe030_0000 0xe03f_ffff PCI IO 1M
72 0xe040_0000 0xefff_ffff Empty 252M
73 0xf400_0000 0xf7ff_ffff Empty 64M
74 0xf800_0000 0xf800_7fff BCSR on CS1 32K
75 0xf800_8000 0xf800_ffff PIB CS2 32K
76 0xf801_0000 0xf801_7fff PIB CS3 32K

Peter Tyser2c7920a2009-05-22 17:23:25 -050086 CONFIG_MPC83xx MPC83xx family for MPC8349, MPC8360 and MPC832x
87 CONFIG_MPC832x MPC832x specific

904. Compilation
91
92 Assuming you're using BASH shell:
93
94 export CROSS_COMPILE=your-cross-compile-prefix
95 cd u-boot
96 make distclean
97 make MPC832XEMDS_config
98 make
99
Peter Tyser2c7920a2009-05-22 17:23:25 -0500100 MPC832x support PCI 33MHz and PCI 66MHz, to make u-boot support PCI:
Dave Liu48aecd92006-12-07 21:14:51 +0800101
102 1)Make sure the DIP SW support PCI mode as described in Section 1.1.
103
104 2)To Make U-Boot image support PCI 33MHz, use
105 Make MPC832XEMDS_HOST_33_config
106
107 3)To Make U-Boot image support PCI 66MHz, use
108 Make MPC832XEMDS_HOST_66M_config
109
1105. Downloading and Flashing Images
111
1125.0 Download over network:
113
114 tftp 10000 u-boot.bin
115
1165.1 Reflash U-boot Image using U-boot
117
118 tftp 20000 u-boot.bin
119 protect off fe000000 fe0fffff
120 erase fe000000 fe0fffff
121 cp.b 20000 fe000000 xxxx
122
123You have to supply the correct byte count with 'xxxx' from the TFTP result log.
124Maybe 3ffff will work too, that corresponds to the erased sectors.

1276. Notes
128 1) The console baudrate for MPC832XEMDS is 115200bps.
