-Freescale MPC837xEMDS Board
------------------------------------------
-1. Board Switches and Jumpers
-1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC837xEMDS 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
-
- 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.
- SW2[1:8]= 0000_0001 refers to bits labeled 1 through 7 is set as "On"
- and bits labeled 8 is set as "Off".
-
-1.1 For the MPC837xEMDS Processor 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]= 0011_0000 (BOOTSEQ, ROMLOC setting)
- SW4[1-8]= 0000_0110 (core PLL setting)
- SW5[1-8]= 1001_1000 (system PLL, boot up from low end of flash)
- SW6[1-8]= 0000_1000 (HRCW is read from NOR FLASH)
- SW7[1-8]= 0110_1101 (TSEC1/2 interface setting - RGMII)
- J3 2-3, TSEC1 LVDD1 with 2.5V
- J6 2-3, TSEC2 LVDD2 with 2.5V
- J9 2-3, CLKIN from osc on board
- J10 removed, CS0 connect to NOR flash; when mounted, CS0 connect to NAND
- J11 removed, Hardware Reset Configuration Word load from FLASH(NOR or NAND)
- mounted, HRCW load from BCSR.
-
- 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 0xe00f_ffff Int Mem Reg Space 1M
- 0xe010_0000 0xe02f_ffff Empty 2M
- 0xe030_0000 0xe03f_ffff PCI IO 1M
- 0xe040_0000 0xe05f_ffff Empty 2M
- 0xe060_0000 0xe060_7fff NAND Flash 32K
- 0xf400_0000 0xf7ff_ffff Empty 64M
- 0xf800_0000 0xf800_7fff BCSR on CS1 32K
- 0xfe00_0000 0xffff_ffff NOR Flash on CS0 32M
-
-3. Definitions
-
-3.1 Explanation of NEW definitions in:
-
- include/configs/MPC837XEMDS.h
-
- CONFIG_MPC83xx MPC83xx family for both MPC837x and MPC8360
- CONFIG_MPC837x MPC837x specific
- CONFIG_MPC837XEMDS MPC837XEMDS board specific
-
-4. Compilation
-
- Assuming you're using BASH shell:
-
- export CROSS_COMPILE=your-cross-compile-prefix
- cd u-boot
- make distclean
- make MPC837XEMDS_config
- make
-
-5. Downloading and Flashing Images
-
-5.0 Download over serial line using Kermit:
-
- loadb
- [Drop to kermit:
- ^\c
- send <u-boot-bin-image>
- c
- ]
-
-
- Or via tftp:
-
- tftp 40000 u-boot.bin
-
-5.1 Reflash U-boot Image using U-boot
-
- tftp 40000 u-boot.bin
- protect off fe000000 fe1fffff
- erase fe000000 fe1fffff
-
- cp.b 40000 fe000000 xxxx
-
-You have to supply the correct byte count with 'xxxx' from the TFTP result log.
-
-6. Notes
- 1) The console baudrate for MPC837XEMDS is 115200bps.
