14# 1. Hardware setting
15###############################################################
16
171.1. Board, BDM settings
18 Install board, BDM, connect each other
19
201.2. Save Register value
21 Boot with board-on monitor program and save the
22 register values with BDM.
23
241.3. Configure flash programmer
25 Check flash memory area in the memory map.
26 0xFFC00000 - 0xFFFFFFFF
27
28 Boot monitor program is at
29 0xFFF00000
30
31 You can program on-board flash memory with VisionClick
32 flash programmer. Set the target flash device as:
33
34 29DL800B
35
36 (?) The flash memory device in the board *is* 29LV800B,
37 but I cannot program it with '29LV800B' option.
38 (in VisionClick flash programming tools)
39 I don't know why...
40
411.4. Save boot monitor program *IMPORTANT*
42 Upload boot monitor program from board to file.
43 boot monitor program starts at 0xFFF00000
44
451.5. Test flash memory programming
46 Try to erase boot program in the flash memory,
47 and re-write them.
48 *WARNING* YOU MUST SAVE BOOT PROGRAM TO FILE
49 BEFORE ERASING FLASH
50

52# 2. U-Boot setting
53###############################################################
54
552.1. Download U-Boot tarball at
56 ftp://ftp.denx.de
57 (The latest version is ppcboot-0.8.1.tar.bz2)
58
59 To extract the archive use the following syntax :
60 > bzip2 -cd ppcboot-0.8.1.tar.bz2 | tar xf -
61
622.2. Add the following lines in '.profile'
63 export PATH=$PATH:/opt/hardhat/devkit/ppc/8xx/bin
64
652.3. Make board specific config, for example:
66 > cd ppcboot-0.8.1
67 > make TQM860L_config
68
69 Now we can build ppcboot bin files.
70 After make all, you must see these files in your
71 ppcboot root directory.
72
73 ppcboot
74 ppcboot.bin
75 ppcboot.srec
76 ppcboot.map
77
782.4. Make your own board directory into the
79 ppcboot-0.8.1/board
80 and make your board-specific files here.
81
82 For exmanple, tqm8xx files are composed of
83 .depend : Nothing
84 Makefile : To make config file
85 config.mk : Sets base address
86 flash.c : Flash memory control files
87 ppcboot.lds : linker(ld) script? (I don't know this yet)
88 tqm8xx.c : DRAM control and board check routines
89
90 And, add your board config lines in the
91 ppcboot-0.8.1/Makefile
92
93 Finally, add config_(your board).h file in the
94 ppcboot-0.8.1/include/
95
96 I've made board/rpxlite directory, and just copied
97 tqm8xx settings for now.
98
99 Rebuild ppcboot for rpxlite board:
100 > make rpxlite_config
101 > make

106
1073.1. My RPXlite files are based on tqm8xx board files.
108 > cd board
109 > cp -r tqm8xx RPXLITE
110 > cd RPXLITE
111 > mv tqm8xx.c RPXLITE.c
112 > cd ../../include
113 > cp config_tqm8xx.h config_RPXLITE.h
114
1153.2. Modified files are:
116 board/RPXLITE/RPXLITE.c /* DRAM-related routines */
117 board/RPXLITE/flash.c /* flash-related routines */
118 board/RPXLITE/config.mk /* set text base address */
119 cpu/mpc8xx/serial.c /* board specific register setting */
120 include/config_RPXLITE.h /* board specific registers */
121
122 See 'reg_config.txt' for register values in detail.
