-Freescale MPC832XEMDS Board
------------------------------------------
-1. Board Switches and Jumpers
-1.0 There are five Dual-In-Line Packages(DIP) Switches on MPC832XE SYS board
- 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" is logic 1.
-
- 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
-
- SW3 is switch 18 as silk-screened onto the board.
- SW4[8] is the bit labeled 8 on Switch 4.
- SW5[1:6] refers to bits labeled 1 through 6 in order on switch 5.
- SW6[7:1] refers to bits labeled 7 through 1 in order on switch 6.
- SW7[1:8]= 0000_0001 refers to bits labeled 1 through 6 is set as "On"
- and bits labeled 8 is set as "Off".
-
-1.1 For the MPC832XEMDS PROTO Board
-
- First, make sure the board default setting is consistent with the document
- shipped with your board. Then apply the following setting:
- SW3[1-8]= 0000_1000 (core PLL setting, core enable)
- SW4[1-8]= 0001_0010 (Flash boot on local bus, system PLL setting)
- SW5[1-8]= 0010_0110 (Boot from high end)
- SW6[1-8]= 0011_0100 (Flash boot on 16 bit local bus)
- SW7[1-8]= 1000_0011 (QE PLL setting)
-
- ENET3/4 MII mode settings:
- J1 1-2 (ETH3_TXER)
- J2 2-3 (MII mode)
- J3 2-3 (MII mode)
- J4 2-3 (ADSL clockOscillator)
- J5 1-2 (ETH4_TXER)
- J6 2-3 (ClockOscillator)
- JP1 removed (don't force PORESET)
- JP2 mounted (ETH4/2 MII)
- JP3 mounted (ETH3 MII)
- JP4 mounted (HRCW from BCSR)
-
- ENET3/4 RMII mode settings:
- J1 1-2 (ETH3_TXER)
- J2 1-2 (RMII mode)
- J3 1-2 (RMII mode)
- J4 2-3 (ADSL clockOscillator)
- J5 1-2 (ETH4_TXER)
- J6 2-3 (ClockOscillator)
- JP1 removed (don't force PORESET)
- JP2 removed (ETH4/2 RMII)
- JP3 removed (ETH3 RMII)
- JP4 removed (HRCW from FLASH)
-
- on board Oscillator: 66M

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

-3. Definitions
-
-3.1 Explanation of NEW definitions in:
-
- include/configs/MPC832XEPB.h
-
- CONFIG_MPC83xx MPC83xx family for MPC8349, MPC8360 and MPC832x
- CONFIG_MPC832x MPC832x specific
- CONFIG_MPC832XEMDS MPC832XEMDS board specific
-
-4. Compilation
-
- Assuming you're using BASH shell:
-
- export CROSS_COMPILE=your-cross-compile-prefix
- cd u-boot
- make distclean
- make MPC832XEMDS_config
- make
-
- MPC832x support PCI 33MHz and PCI 66MHz, to make u-boot support PCI:
-
- 1)Make sure the DIP SW support PCI mode as described in Section 1.1.
-
- 2)To Make U-Boot image support PCI 33MHz, use
- Make MPC832XEMDS_HOST_33_config
-
- 3)To Make U-Boot image support PCI 66MHz, use
- Make MPC832XEMDS_HOST_66M_config
-
-5. Downloading and Flashing Images
-
-5.0 Download over network:
-
- tftp 10000 u-boot.bin
-
-5.1 Reflash U-boot Image using U-boot
-
- tftp 20000 u-boot.bin
- protect off fe000000 fe0fffff
- erase fe000000 fe0fffff
- cp.b 20000 fe000000 xxxx
-
-You have to supply the correct byte count with 'xxxx' from the TFTP result log.
-Maybe 3ffff will work too, that corresponds to the erased sectors.
-
-
-6. Notes
- 1) The console baudrate for MPC832XEMDS is 115200bps.
