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_config

make MPC8360EMDS_XX_config
|
||||
make
|

|

MPC8360 support PCI in host and slave mode.
|
||||
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_HOST_66_config
|
||||
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_HOST_33_config
|
||||
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_SLAVE_config
|
||||
2) Make MPC8360EMDS_XX_SLAVE_config
|
||||
|
||||
(where XX is:
|
||||
33 - 33.33MHz oscillator
|
||||
66 - 66MHz oscillator)
