9 The Binutils in current ELDK toolchain will not support MPC85xx
10 chip. You need to use binutils-2.14.tar.bz2 (or newer) from
11 http://ftp.gnu.org/gnu/binutils.
13 The 8540/8560 ADS code base is known to compile using:
14 gcc (GCC) 3.2.2 20030217 (Yellow Dog Linux 3.0 3.2.2-2a)
17 1. SWITCH SETTINGS & JUMPERS
21 For some reason, the HW designers describe the switch settings
22 in terms of 0 and 1, and then map that to physical switches where
23 the label "On" refers to logic 0 and "Off" (unlabeled) is logic 1.
24 Luckily, we're SW types and virtual settings are handled daily.
26 The switches for the Rev A board are numbered differently than
27 for the Pilot board. Oh yeah.
29 Switch bits are numbered 1 through, like, 4 6 8 or 10, but the
30 bits may contribute to signals that are numbered based at 0,
31 and some of those signals may be high-bit-number-0 too. Heed
32 well the names and labels and do not get confused.
37 SW18 is switch 18 as silk-screened onto the board.
38 SW4[8] is the bit labeled 8 on Switch 4.
39 SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2
40 SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3
42 1.1 For the MPC85xxADS Pilot Board
44 First, make sure the board default setting is consistent with the document
45 shipped with your board. Then apply the following changes:
46 SW3[1-6]="all OFF" (boot from 32bit flash, no boot sequence is used)
47 SW10[2-6]="all OFF" (turn on CPM SCC for serial port,works for 8540/8560)
48 SW11[2]='OFF for 8560, ON for 8540' (toggle 8540.8560 mode)
49 SW11[7]='ON' (rev2), 'OFF' (rev1)
50 SW4[7-8]="OFF OFF" (enable serial ports,I'm using the top serial connector)
51 SW22[1-4]="OFF OFF ON OFF"
52 SW5[1-10[="ON ON OFF OFF OFF OFF OFF OFF OFF OFF"
53 J1 = "Enable Prog" (Make sure your flash is programmable for development)
55 If you want to test PCI functionality with a 33Mhz PCI card, you will
56 have to change the system clock from the default 66Mhz to 33Mhz by
57 setting SW15[1]="OFF" and SW17[8]="OFF". After that you may also need
58 double your platform clock(SW6) because the system clock is now only
59 half of its original value. For example, if at 66MHz your system
60 clock showed SW6[0:1] = 01, then at 33MHz SW6[0:1] it should be 10.
68 Hmmm... That SW6 setting description is incomplete but it works.
71 1.3 For the MPC85xxADS Rev A Board
73 As shipped, the board should be a 33MHz PCI bus with a CPU Clock
76 Clocks: CPU: 825 MHz, CCB: 330 MHz, DDR: 165 MHz, LBC: 82 MHz
78 For 33MHz PCI, the switch settings should be like this:
80 SW18[7:1] = 0100001 = M==33 => 33MHz
81 SW18[8] = 1 => PWD Divider == 16
82 SW16[1:2] = 11 => N == 16 as PWD==1
84 Use the magical formula:
85 Fout (MHz) = 16 * M / N = 16 * 33 / 16 = 33 MHz
87 SW7[1:4] = 1010 = 10 => 10 x 33 = 330 CCB Sysclk
88 SW7[5:6] = 01 => 5:2 x 330 = 825 Core clock
91 For 66MHz PCI, the switch settings should be like this:
93 SW18[7:1] = 0100001 = M==33 => 33MHz
94 SW18[8] = 0 => PWD Divider == 1
95 SW16[1:2] = 01 => N == 8 as PWD == 0
97 Use the magical formula:
98 Fout (MHz) = 16 * M / N = 16 * 33 / 8 = 66 MHz
100 SW7[1:4] = 0101 = 5 => 5 x 66 = 330 CCB Sysclk
101 SW7[5:6] = 01 => 5:2 x 330 = 825 Core clock
103 In order to use PCI-X (only in the first PCI slot. The one with
104 the RIO connector), you need to set SW1[4] (config) to 1 (off).
105 Also, configure the board to run PCI at 66 MHz.
107 2. MEMORY MAP TO WORK WITH LINUX KERNEL
109 2.1. For the initial bringup, we adopted a consistent memory scheme
110 between U-Boot and linux kernel, you can customize it based on your
113 0x0000_0000 0x7fff_ffff DDR 2G
114 0x8000_0000 0x9fff_ffff PCI MEM 512M
115 0xc000_0000 0xdfff_ffff Rapid IO 512M
116 0xe000_0000 0xe00f_ffff CCSR 1M
117 0xe200_0000 0xe2ff_ffff PCI IO 16M
118 0xf000_0000 0xf7ff_ffff SDRAM 128M
119 0xf800_0000 0xf80f_ffff BCSR 1M
120 0xff00_0000 0xffff_ffff FLASH (boot bank) 16M
122 2.2 We are submitting Linux kernel patches for MPC8540 and MPC8560. You
123 can download them from linuxppc-2.4 public source. Please make sure the
124 kernel's ppcboot.h is consistent with U-Boot's u-boot.h. You can use two
125 default configuration files as your starting points to configure the
127 arch/powerpc/configs/mpc8540_ads_defconfig
128 arch/powerpc/configs/mpc8560_ads_defconfig
130 3. DEFINITIONS AND COMPILATION
132 3.1 Explanation on NEW definitions in:
133 include/configs/MPC8540ADS.h
134 include/configs/MPC8560ADS.h
136 CONFIG_BOOKE BOOKE(e.g. Motorola MPC85xx, AMCC 440, etc)
137 CONFIG_E500 BOOKE e500 family(Motorola)
138 CONFIG_MPC85xx MPC8540,MPC8560 and their derivatives
139 CONFIG_MPC8540 MPC8540 specific
140 CONFIG_MPC8540ADS MPC8540ADS board specific
141 CONFIG_MPC8560ADS MPC8560ADS board specific
142 CONFIG_TSEC_ENET Use on-chip 10/100/1000 ethernet for networking
143 CONFIG_SPD_EEPROM Use SPD EEPROM for DDR auto configuration, you can
144 also manual config the DDR after undef this
146 CONFIG_DDR_ECC only for ECC DDR module
147 CONFIG_SYS_FSL_ERRATUM_DDR_MSYNC_IN DLL fix on some ADS boards needed
149 CONFIG_HAS_FEC If an FEC is on chip, set to 1, else 0.
151 Other than the above definitions, the rest in the config files are
157 Assuming you're using BASH shell:
159 export CROSS_COMPILE=your-cross-compile-prefix
162 make MPC8560ADS_config (or make MPC8540ADS_config)
167 4.1 When connecting with kermit, the following commands must be present.in
168 your .kermrc file. These are especially important when booting as
169 MPC8560, as the serial console will not work without them:
172 set carrier-watch off
174 set flow-control none
178 4.2 Sometimes after U-Boot is up, the 'tftp' won't work well with TSEC
179 ethernet. If that happens, you can try the following steps to make
182 MPC8560ADS>tftp 1000000 pImage
183 (if it hangs, use Ctrl-C to quit)
184 MPC8560ADS>nm fdf24524
187 >. (to quit this memory operation)
188 MPC8560ADS>tftp 1000000 pImage
190 4.3 If you're one of the early developers using the Rev1 8540/8560 chips,
191 please use U-Boot 1.0.0, as the newer silicon will only support Rev2
192 and future revisions of 8540/8560.
195 4.4 Reflash U-Boot Image using U-Boot
197 tftp 10000 u-boot.bin
198 protect off fff80000 ffffffff
199 erase fff80000 ffffffff
200 cp.b 10000 fff80000 80000
203 4.5 Reflash U-Boot with a BDI-2000
205 BDI> erase 0xFFF80000 0x4000 0x20
206 BDI> prog 0xfff80000 u-boot.bin.8560ads
