| 2 | ----------------------------------------- |
| 3 | 1. Board Switches and Jumpers |
| 4 | 1.0 There are five Dual-In-Line Packages(DIP) Switches on MPC832XE SYS board |
| 5 | For some reason, the HW designers describe the switch settings |
| 6 | in terms of 0 and 1, and then map that to physical switches where |
| 7 | the label "On" refers to logic 0 and "Off" is logic 1. |
| 8 | |
| 9 | Switch bits are numbered 1 through, like, 4 6 8 or 10, but the |
| 10 | bits may contribute to signals that are numbered based at 0, |
| 11 | and some of those signals may be high-bit-number-0 too. Heed |
| 12 | well the names and labels and do not get confused. |
| 13 | |
| 14 | "Off" == 1 |
| 15 | "On" == 0 |
| 16 | |
| 17 | SW3 is switch 18 as silk-screened onto the board. |
| Thomas Weber | 6726631 | 2012-03-24 22:44:01 +0000 | [diff] [blame] | 18 | SW4[8] is the bit labeled 8 on Switch 4. |
| Dave Liu | 1dcb5df | 2006-12-07 21:14:51 +0800 | [diff] [blame] | 19 | SW5[1:6] refers to bits labeled 1 through 6 in order on switch 5. |
| 20 | SW6[7:1] refers to bits labeled 7 through 1 in order on switch 6. |
| 21 | SW7[1:8]= 0000_0001 refers to bits labeled 1 through 6 is set as "On" |
| 22 | and bits labeled 8 is set as "Off". |
| 23 | |
| 24 | 1.1 For the MPC832XEMDS PROTO Board |
| 25 | |
| 26 | First, make sure the board default setting is consistent with the document |
| 27 | shipped with your board. Then apply the following setting: |
| 28 | SW3[1-8]= 0000_1000 (core PLL setting, core enable) |
| 29 | SW4[1-8]= 0001_0010 (Flash boot on local bus, system PLL setting) |
| 30 | SW5[1-8]= 0010_0110 (Boot from high end) |
| 31 | SW6[1-8]= 0011_0100 (Flash boot on 16 bit local bus) |
| 32 | SW7[1-8]= 1000_0011 (QE PLL setting) |
| 33 | |
| 34 | ENET3/4 MII mode settings: |
| 35 | J1 1-2 (ETH3_TXER) |
| 36 | J2 2-3 (MII mode) |
| 37 | J3 2-3 (MII mode) |
| 38 | J4 2-3 (ADSL clockOscillator) |
| 39 | J5 1-2 (ETH4_TXER) |
| 40 | J6 2-3 (ClockOscillator) |
| 41 | JP1 removed (don't force PORESET) |
| 42 | JP2 mounted (ETH4/2 MII) |
| 43 | JP3 mounted (ETH3 MII) |
| 44 | JP4 mounted (HRCW from BCSR) |
| 45 | |
| 46 | ENET3/4 RMII mode settings: |
| 47 | J1 1-2 (ETH3_TXER) |
| 48 | J2 1-2 (RMII mode) |
| 49 | J3 1-2 (RMII mode) |
| 50 | J4 2-3 (ADSL clockOscillator) |
| 51 | J5 1-2 (ETH4_TXER) |
| 52 | J6 2-3 (ClockOscillator) |
| 53 | JP1 removed (don't force PORESET) |
| 54 | JP2 removed (ETH4/2 RMII) |
| 55 | JP3 removed (ETH3 RMII) |
| 56 | JP4 removed (HRCW from FLASH) |
| 57 | |
| 58 | on board Oscillator: 66M |

| 61 | 2. Memory Map |
| 62 | |
| 63 | 2.1 The memory map should look pretty much like this: |
| 64 | |
| 65 | 0x0000_0000 0x7fff_ffff DDR 2G |
| 66 | 0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M |
| 67 | 0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M |
| 68 | 0xc000_0000 0xdfff_ffff Empty 512M |
| 69 | 0xe000_0000 0xe01f_ffff Int Mem Reg Space 2M |
| 70 | 0xe020_0000 0xe02f_ffff Empty 1M |
| 71 | 0xe030_0000 0xe03f_ffff PCI IO 1M |
| 72 | 0xe040_0000 0xefff_ffff Empty 252M |
| 73 | 0xf400_0000 0xf7ff_ffff Empty 64M |
| 74 | 0xf800_0000 0xf800_7fff BCSR on CS1 32K |
| 75 | 0xf800_8000 0xf800_ffff PIB CS2 32K |
| 76 | 0xf801_0000 0xf801_7fff PIB CS3 32K |
| 77 | 0xfe00_0000 0xfeff_ffff FLASH on CS0 16M |

| 90 | 4. Compilation |
| 91 | |
| 92 | Assuming you're using BASH shell: |
| 93 | |
| 94 | export CROSS_COMPILE=your-cross-compile-prefix |
| 95 | cd u-boot |
| 96 | make distclean |
| 97 | make MPC832XEMDS_config |

| Dave Liu | 1dcb5df | 2006-12-07 21:14:51 +0800 | [diff] [blame] | 101 | |
| 102 | 1)Make sure the DIP SW support PCI mode as described in Section 1.1. |
| 103 | |
| 104 | 2)To Make U-Boot image support PCI 33MHz, use |
| 105 | Make MPC832XEMDS_HOST_33_config |
| 106 | |
| 107 | 3)To Make U-Boot image support PCI 66MHz, use |
| 108 | Make MPC832XEMDS_HOST_66M_config |
| 109 | |
| 110 | 5. Downloading and Flashing Images |
| 111 | |
| 112 | 5.0 Download over network: |
| 113 | |
| 114 | tftp 10000 u-boot.bin |
| 115 | |
| Bin Meng | 7557405 | 2016-02-05 19:30:11 -0800 | [diff] [blame] | 116 | 5.1 Reflash U-Boot Image using U-Boot |
| Dave Liu | 1dcb5df | 2006-12-07 21:14:51 +0800 | [diff] [blame] | 117 | |
| 118 | tftp 20000 u-boot.bin |
| 119 | protect off fe000000 fe0fffff |
| 120 | erase fe000000 fe0fffff |
| 121 | cp.b 20000 fe000000 xxxx |
| 122 | |
| 123 | You have to supply the correct byte count with 'xxxx' from the TFTP result log. |
| 124 | Maybe 3ffff will work too, that corresponds to the erased sectors. |
| 125 | |

| 127 | 6. Notes |
| 128 | 1) The console baudrate for MPC832XEMDS is 115200bps. |
