Freescale MPC8360EMDS Board
|
|
-----------------------------------------
|
|
1. Board Switches and Jumpers
|
|
1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC8360EMDS 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
|
|
|
|
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.
|
|
SW3[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 There are three type boards for MPC8360E silicon up to now, They are
|
|
|
|
* MPC8360E-MDS-PB PROTO (a.k.a 8360SYS PROTOTYPE)
|
|
* MPC8360E-MDS-PB PILOT (a.k.a 8360SYS PILOT)
|
|
* MPC8360EA-MDS-PB PROTO (a.k.a 8360SYS2 PROTOTYPE)
|
|
|
|
1.2 For all the MPC8360EMDS 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_0100 (HRCW setting value is performed on local bus)
|
|
SW4[1-8]= 0011_0000 (Flash boot on local bus)
|
|
SW9[1-8]= 0110_0110 (PCI Mode enabled. HRCW is read from FLASH)
|
|
SW10[1-8]= 0000_1000 (core PLL setting)
|
|
SW11[1-8]= 0000_0100 (SW11 is on the another side of the board)
|
|
JP6 1-2
|
|
on board Oscillator: 66M
|
|
|
|
1.3 Since different board/chip rev. combinations have AC timing issues,
|
|
u-boot forces RGMII-ID (RGMII with Internal Delay) mode on by default
|
|
by the patch (mpc83xx: Disable G1TXCLK, G2TXCLK h/w buffers).
|
|
|
|
When the rev2.x silicon mount on these boards, and if you are using
|
|
u-boot version after this patch, to make the ethernet interfaces usable,
|
|
and to enable RGMII-ID on your board, you have to setup the jumpers
|
|
correctly.
|
|
|
|
* MPC8360E-MDS-PB PROTO
|
|
nothing to do
|
|
* MPC8360E-MDS-PB PILOT
|
|
JP9 and JP8 should be ON
|
|
* MPC8360EA-MDS-PB PROTO
|
|
JP2 and JP3 should be ON
|
|
|
|
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
|
|
0xf000_0000 0xf3ff_ffff Local Bus SDRAM 64M
|
|
0xf400_0000 0xf7ff_ffff Empty 64M
|
|
0xf800_0000 0xf800_7fff BCSR on CS1 32K
|
|
0xf800_8000 0xf800_ffff PIB CS4 32K
|
|
0xf801_0000 0xf801_7fff PIB CS5 32K
|
|
0xfe00_0000 0xfeff_ffff FLASH on CS0 16M
|
|
|
|
|
|
3. Definitions
|
|
|
|
3.1 Explanation of NEW definitions in:
|
|
|
|
include/configs/MPC8360EMDS.h
|
|
|
|
CONFIG_MPC83xx MPC83xx family for both MPC8349 and MPC8360
|
|
CONFIG_MPC8360 MPC8360 specific
|
|
CONFIG_MPC8360EMDS MPC8360EMDS board specific
|
|
|
|
4. Compilation
|
|
|
|
MPC8360EMDS shipped with 33.33MHz or 66MHz oscillator(check U41 chip).
|
|
|
|
Assuming you're using BASH shell:
|
|
|
|
export CROSS_COMPILE=your-cross-compile-prefix
|
|
cd u-boot
|
|
make distclean
|
|
make MPC8360EMDS_XX_config
|
|
make
|
|
|
|
MPC8360EMDS support ATM, PCI in host and slave mode.
|
|
|
|
To make u-boot support ATM :
|
|
1) Make MPC8360EMDS_XX_ATM_config
|
|
|
|
To make u-boot support PCI host 66M :
|
|
1) DIP SW support PCI mode as described in Section 1.1.
|
|
2) Make MPC8360EMDS_XX_HOST_66_config
|
|
|
|
To make u-boot support PCI host 33M :
|
|
1) DIP SW setting is similar as Section 1.1, except for SW3[4] is 1
|
|
2) Make MPC8360EMDS_XX_HOST_33_config
|
|
|
|
To make u-boot support PCI slave 66M :
|
|
1) DIP SW setting is similar as Section 1.1, except for SW9[3] is 1
|
|
2) Make MPC8360EMDS_XX_SLAVE_config
|
|
|
|
(where XX is:
|
|
33 - 33.33MHz oscillator
|
|
66 - 66MHz oscillator)
|
|
|
|
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 10000 u-boot.bin
|
|
|
|
5.1 Reflash U-boot Image using U-boot
|
|
|
|
tftp 20000 u-boot.bin
|
|
protect off fef00000 fef3ffff
|
|
erase fef00000 fef3ffff
|
|
|
|
cp.b 20000 fef00000 xxxx
|
|
|
|
or
|
|
|
|
cp.b 20000 fef00000 3ffff
|
|
|
|
|
|
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
