| |
| 0. Toolchain |
| |
| The Binutils in current ELDK toolchain will not support MPC85xx |
| chip. You need to use binutils-2.14.tar.bz2 (or newer) from |
| http://ftp.gnu.org/gnu/binutils. |
| |
| The 8540/8560 ADS code base is known to compile using: |
| gcc (GCC) 3.2.2 20030217 (Yellow Dog Linux 3.0 3.2.2-2a) |
| |
| |
| 1. SWITCH SETTINGS & JUMPERS |
| |
| 1.0 Nomenclature |
| |
| For some reason, the HW designers describe the switch settings |
| in terms of 0 and 1, and then map that to physical switches where |
| the label "On" refers to logic 0 and "Off" (unlabeled) is logic 1. |
| Luckily, we're SW types and virtual settings are handled daily. |
| |
| The switches for the Rev A board are numbered differently than |
| for the Pilot board. Oh yeah. |
| |
| Switch bits are numbered 1 through, like, 4 6 8 or 10, but the |
| bits may contribute to signals that are numbered based at 0, |
| and some of those signals may be high-bit-number-0 too. Heed |
| well the names and labels and do not get confused. |
| |
| "Off" == 1 |
| "On" == 0 |
| |
| SW18 is switch 18 as silk-screened onto the board. |
| SW4[8] is the bit labeled 8 on Switch 4. |
| SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2 |
| SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3 |
| |
| 1.1 For the MPC85xxADS Pilot Board |
| |
| First, make sure the board default setting is consistent with the document |
| shipped with your board. Then apply the following changes: |
| SW3[1-6]="all OFF" (boot from 32bit flash, no boot sequence is used) |
| SW10[2-6]="all OFF" (turn on CPM SCC for serial port,works for 8540/8560) |
| SW11[2]='OFF for 8560, ON for 8540' (toggle 8540.8560 mode) |
| SW11[7]='ON' (rev2), 'OFF' (rev1) |
| SW4[7-8]="OFF OFF" (enable serial ports,I'm using the top serial connector) |
| SW22[1-4]="OFF OFF ON OFF" |
| SW5[1-10[="ON ON OFF OFF OFF OFF OFF OFF OFF OFF" |
| J1 = "Enable Prog" (Make sure your flash is programmable for development) |
| |
| If you want to test PCI functionality with a 33Mhz PCI card, you will |
| have to change the system clock from the default 66Mhz to 33Mhz by |
| setting SW15[1]="OFF" and SW17[8]="OFF". After that you may also need |
| double your platform clock(SW6) because the system clock is now only |
| half of its original value. For example, if at 66MHz your system |
| clock showed SW6[0:1] = 01, then at 33MHz SW6[0:1] it should be 10. |
| |
| SW17[8] ------+ SW6 |
| SW15[1] ----+ | [0:1] |
| V V V V |
| 33MHz 1 1 1 0 |
| 66MHz 0 0 0 1 |
| |
| Hmmm... That SW6 setting description is incomplete but it works. |
| |
| |
| 1.3 For the MPC85xxADS Rev A Board |
| |
| As shipped, the board should be a 33MHz PCI bus with a CPU Clock |
| rate of 825 +/- fuzz: |
| |
| Clocks: CPU: 825 MHz, CCB: 330 MHz, DDR: 165 MHz, LBC: 82 MHz |
| |
| For 33MHz PCI, the switch settings should be like this: |
| |
| SW18[7:1] = 0100001 = M==33 => 33MHz |
| SW18[8] = 1 => PWD Divider == 16 |
| SW16[1:2] = 11 => N == 16 as PWD==1 |
| |
| Use the magical formula: |
| Fout (MHz) = 16 * M / N = 16 * 33 / 16 = 33 MHz |
| |
| SW7[1:4] = 1010 = 10 => 10 x 33 = 330 CCB Sysclk |
| SW7[5:6] = 01 => 5:2 x 330 = 825 Core clock |
| |
| |
| For 66MHz PCI, the switch settings should be like this: |
| |
| SW18[7:1] = 0100001 = M==33 => 33MHz |
| SW18[8] = 0 => PWD Divider == 1 |
| SW16[1:2] = 01 => N == 8 as PWD == 0 |
| |
| Use the magical formula: |
| Fout (MHz) = 16 * M / N = 16 * 33 / 8 = 66 MHz |
| |
| SW7[1:4] = 0101 = 5 => 5 x 66 = 330 CCB Sysclk |
| SW7[5:6] = 01 => 5:2 x 330 = 825 Core clock |
| |
| In order to use PCI-X (only in the first PCI slot. The one with |
| the RIO connector), you need to set SW1[4] (config) to 1 (off). |
| Also, configure the board to run PCI at 66 MHz. |
| |
| 2. MEMORY MAP TO WORK WITH LINUX KERNEL |
| |
| 2.1. For the initial bringup, we adopted a consistent memory scheme |
| between U-Boot and linux kernel, you can customize it based on your |
| system requirements: |
| |
| 0x0000_0000 0x7fff_ffff DDR 2G |
| 0x8000_0000 0x9fff_ffff PCI MEM 512M |
| 0xc000_0000 0xdfff_ffff Rapid IO 512M |
| 0xe000_0000 0xe00f_ffff CCSR 1M |
| 0xe200_0000 0xe2ff_ffff PCI IO 16M |
| 0xf000_0000 0xf7ff_ffff SDRAM 128M |
| 0xf800_0000 0xf80f_ffff BCSR 1M |
| 0xff00_0000 0xffff_ffff FLASH (boot bank) 16M |
| |
| 2.2 We are submitting Linux kernel patches for MPC8540 and MPC8560. You |
| can download them from linuxppc-2.4 public source. Please make sure the |
| kernel's ppcboot.h is consistent with U-Boot's u-boot.h. You can use two |
| default configuration files as your starting points to configure the |
| kernel: |
| arch/powerpc/configs/mpc8540_ads_defconfig |
| arch/powerpc/configs/mpc8560_ads_defconfig |
| |
| 3. DEFINITIONS AND COMPILATION |
| |
| 3.1 Explanation on NEW definitions in: |
| include/configs/MPC8540ADS.h |
| include/configs/MPC8560ADS.h |
| |
| CONFIG_BOOKE BOOKE(e.g. Motorola MPC85xx, AMCC 440, etc) |
| CONFIG_E500 BOOKE e500 family(Motorola) |
| CONFIG_MPC85xx MPC8540,MPC8560 and their derivatives |
| CONFIG_ARCH_MPC8540 MPC8540 specific |
| CONFIG_TSEC_ENET Use on-chip 10/100/1000 ethernet for networking |
| CONFIG_SPD_EEPROM Use SPD EEPROM for DDR auto configuration, you can |
| also manual config the DDR after undef this |
| definition. |
| CONFIG_DDR_ECC only for ECC DDR module |
| CONFIG_SYS_FSL_ERRATUM_DDR_MSYNC_IN DLL fix on some ADS boards needed |
| for more stability. |
| CONFIG_HAS_FEC If an FEC is on chip, set to 1, else 0. |
| |
| Other than the above definitions, the rest in the config files are |
| straightforward. |
| |
| |
| 3.2 Compilation |
| |
| Assuming you're using BASH shell: |
| |
| export CROSS_COMPILE=your-cross-compile-prefix |
| cd u-boot |
| make distclean |
| make MPC8560ADS_config (or make MPC8540ADS_config) |
| make |
| |
| 4. Notes: |
| |
| 4.1 When connecting with kermit, the following commands must be present.in |
| your .kermrc file. These are especially important when booting as |
| MPC8560, as the serial console will not work without them: |
| |
| set speed 115200 |
| set carrier-watch off |
| set handshake none |
| set flow-control none |
| robust |
| |
| |
| 4.2 Sometimes after U-Boot is up, the 'tftp' won't work well with TSEC |
| ethernet. If that happens, you can try the following steps to make |
| network work: |
| |
| MPC8560ADS>tftp 1000000 pImage |
| (if it hangs, use Ctrl-C to quit) |
| MPC8560ADS>nm fdf24524 |
| >0 |
| >1 |
| >. (to quit this memory operation) |
| MPC8560ADS>tftp 1000000 pImage |
| |
| 4.3 If you're one of the early developers using the Rev1 8540/8560 chips, |
| please use U-Boot 1.0.0, as the newer silicon will only support Rev2 |
| and future revisions of 8540/8560. |
| |
| |
| 4.4 Reflash U-Boot Image using U-Boot |
| |
| tftp 10000 u-boot.bin |
| protect off fff80000 ffffffff |
| erase fff80000 ffffffff |
| cp.b 10000 fff80000 80000 |
| |
| |
| 4.5 Reflash U-Boot with a BDI-2000 |
| |
| BDI> erase 0xFFF80000 0x4000 0x20 |
| BDI> prog 0xfff80000 u-boot.bin.8560ads |
| BDI> verify |
