41.	Board Switches and Jumpers
5
6	S3 is used to set CONFIG_SYS_RESET_SOURCE.
7
8	To boot the image at 0xFE000000 in NOR flash, use these DIP
9	switch settings for S3 S4:
10
11	+------+	+------+
12	|      |	| **** |
13	| **** |	|      |
14	+------+ ON	+------+ ON
15	  4321		  4321
16	(where the '*' indicates the position of the tab of the switch.)
17
18	To boot the image at the beginning of NAND flash, use these
19	DIP switch settings for S3 S4:
20
21	+------+	+------+
22	| *    |	|  *** |
23	|  *** |	| *    |
24	+------+ ON	+------+ ON
25	  4321		  4321
26	(where the '*' indicates the position of the tab of the switch.)
27
28	When booting from NAND, use u-boot-nand.bin, not u-boot.bin.
29
302.	Memory Map
31	The memory map looks like this:
32
33	0x0000_0000	0x07ff_ffff	DDR		 128M
34	0x8000_0000	0x8fff_ffff	PCI MEM		 256M
35	0x9000_0000	0x9fff_ffff	PCI_MMIO	 256M
36	0xe000_0000	0xe00f_ffff	IMMR		 1M
37	0xe200_0000	0xe20f_ffff	PCI IO		 16M
38	0xe280_0000	0xe280_7fff	NAND FLASH (CS1) 32K
39	0xf000_0000	0xf001_ffff	VSC7385 (CS2)	 128K
40	0xfa00_0000	0xfa00_7fff	Board Status/	 32K
41					LED Control (CS3)
42	0xfe00_0000	0xfe7f_ffff	NOR FLASH (CS0)	 8M
43
44	When booting from NAND, NAND flash is CS0 and NOR flash
45	is CS1.

473.	Definitions
48
493.1	Explanation of NEW definitions in:
50
51	include/configs/MPC8313ERDB.h
52
53	CONFIG_MPC83xx		MPC83xx family
54	CONFIG_MPC831x		MPC831x specific
55	CONFIG_MPC8313ERDB	MPC8313ERDB board specific
56
574.	Compilation
58
59	Assuming you're using BASH (or similar) as your shell:
60
61	export CROSS_COMPILE=your-cross-compiler-prefix-
62	make distclean
63	make MPC8313ERDB_XXX_config
64	(where XXX is:
65	   33 - 33 MHz oscillator, boot from NOR flash
66	   66 - 66 MHz oscillator, boot from NOR flash
67	   NAND_33 - 33 MHz oscillator, boot from NAND flash
68	   NAND_66 - 66 MHz oscillator, boot from NAND flash)
69	make
70
715.	Downloading and Flashing Images
72
735.1	Reflash U-boot Image using U-boot
74
75	NOR flash:
76
77	=>run tftpflash
78
79	You may want to try
80	=>tftpboot $loadaddr $uboot
81	first, to make sure that the TFTP load will succeed before it
82	goes ahead and wipes out your current firmware.  And of course,
83	have an alternate means of programming the flash available
84	if the new u-boot doesn't boot.
85
86	NAND flash:
87
88	=>tftpboot $loadaddr <filename>
89	=>nand erase 0 0x80000
90	=>nand write $loadaddr 0 0x80000
91
92	...where 0x80000 is the filesize rounded up to
93	the next 0x20000 increment.
94
955.2	Downloading and Booting Linux Kernel
96
97	Ensure that all networking-related environment variables are set
98	properly (including ipaddr, serverip, gatewayip (if needed),
99	netmask, ethaddr, eth1addr, rootpath (if using NFS root),
100	fdtfile, and bootfile).
101
102	Then, do one of the following, depending on whether you
103	want an NFS root or a ramdisk root:
104
105	=>run nfsboot
106	or
107	=>run ramboot
108
1096	Notes
110
111	The console baudrate for MPC8313ERDB is 115200bps.
