Jean-Christophe PLAGNIOL-VILLARD6d0f6bc2008-10-16 15:01:15 +02006 S3 is used to set CONFIG_SYS_RESET_SOURCE.
Dave Liu8bd522c2008-01-11 18:48:24 +08007
8 To boot the image at 0xFE000000 in NOR flash, use these DIP
Dave Liube5a7192008-04-15 13:12:23 +08009 switch settings for S3 S4:
Dave Liu8bd522c2008-01-11 18:48:24 +080010
11 +------+ +------+
12 | | | **** |
13 | **** | | |
14 +------+ ON +------+ ON
15 4321 4321
16 (where the '*' indicates the position of the tab of the switch.)
17
Anton Vorontsov2e950042009-11-24 20:12:12 +030018 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.

Dave Liu8bd522c2008-01-11 18:48:24 +0800302. 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 0xe030_0000 0xe03f_ffff PCI IO 1M
38 0xe060_0000 0xe060_7fff NAND FLASH (CS1) 32K
39 0xfe00_0000 0xfe7f_ffff NOR FLASH (CS0) 8M
40
Anton Vorontsov2e950042009-11-24 20:12:12 +030041 When booting from NAND, NAND flash is CS0 and NOR flash
42 is CS1.

463.1 Explanation of NEW definitions in:
47
48 include/configs/MPC8315ERDB.h
49
50 CONFIG_MPC83xx MPC83xx family
51 CONFIG_MPC831x MPC831x specific
52 CONFIG_MPC8315 MPC8315 specific
53 CONFIG_MPC8315ERDB MPC8315ERDB board specific
54
554. Compilation
56
57 Assuming you're using BASH (or similar) as your shell:
58
59 export CROSS_COMPILE=your-cross-compiler-prefix-
60 make distclean
Anton Vorontsov2e950042009-11-24 20:12:12 +030061 make MPC8315ERDB_config (or MPC8315ERDB_NAND_config for u-boot-nand.bin)
Dave Liu8bd522c2008-01-11 18:48:24 +080062 make all
63
645. Downloading and Flashing Images
65
Bin Menga1875592016-02-05 19:30:11 -0800665.1 Reflash U-Boot Image using U-Boot
Dave Liu8bd522c2008-01-11 18:48:24 +080067
Anton Vorontsov2e950042009-11-24 20:12:12 +030068 NOR flash:
69
Dave Liu8bd522c2008-01-11 18:48:24 +080070 tftp 40000 u-boot.bin
71 protect off all
72 erase fe000000 fe1fffff
73
74 cp.b 40000 fe000000 xxxx
75 protect on all
76
77 You have to supply the correct byte count with 'xxxx'
78 from the TFTP result log.
79
Anton Vorontsov2e950042009-11-24 20:12:12 +030080 NAND flash:
81
82 =>tftpboot $loadaddr <filename>
83 =>nand erase 0 0x80000
84 =>nand write $loadaddr 0 0x80000
85
86 ...where 0x80000 is the filesize rounded up to
87 the next 0x20000 increment.

Dave Liu8bd522c2008-01-11 18:48:24 +0800895.2 Downloading and Booting Linux Kernel
90
91 Ensure that all networking-related environment variables are set
92 properly (including ipaddr, serverip, gatewayip (if needed),
93 netmask, ethaddr, eth1addr, rootpath (if using NFS root),
94 fdtfile, and bootfile).
95
96 Then, do one of the following, depending on whether you
97 want an NFS root or a ramdisk root:
98
99 =>run nfsboot
100 or
101 =>run ramboot
