1Freescale MPC837xEMDS Board
2-----------------------------------------
31.	Board Switches and Jumpers
41.0	There are four Dual-In-Line Packages(DIP) Switches on MPC837xEMDS 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	SW4[8] is the bit labeled 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".

221.1	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.

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
52	0xe060_0000	0xe060_7fff	NAND Flash		32K
53	0xf400_0000	0xf7ff_ffff	Empty			64M
54	0xf800_0000	0xf800_7fff	BCSR on CS1		32K

674. 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
775. Downloading and Flashing Images
78
795.0 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
935.1 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
101You have to supply the correct byte count with 'xxxx' from the TFTP result log.
