COBRA5272 board.

CONFIGURING
|
||||
-----------
|
||||
|
||||
1. Modify include/configs/cobra5272.h acc. to your prefs
|
||||
|
||||
2. If necessary, modify board/cobra5272/config.mk (see below)
|
||||
|
||||
3.
|
||||
|
||||
> make cobra5272_config
|
||||
|
||||
> make
|
||||
|
||||
|
||||
Please refer to u-boot README (general info, u-boot-x-x-x/README),
|
||||
to u-boot-x-x-x/doc/README.COBRA5272 and
|
||||
to the comments in u-boot-x-x-x/include/configs/cobra5272.h
|
||||
|
||||
Configuring u-boot is done by commenting/uncommenting preprocessor defines.
|
||||
|
||||
Default configuration is
|
||||
|
||||
FLASH version (for further info see subsection below)
|
||||
link address 0xffe00000
|
||||
|
||||
16 MB RAM
|
||||
|
||||
network enabled
|
||||
no default IP address for target, host set, no MACaddress set
|
||||
|
||||
bootdelay for autoboot 5 sec.
|
||||
autoboot disabled
|
||||
|
||||
|
||||
#-----------------------------------
|
||||
# u-boot FLASH version & RAM version
|
||||
#-----------------------------------
|
||||
|
||||
The u-boot bootloader for Coldfire processors can be configured
|
||||
|
||||
1. as a standalone bootloader residing in flash & relocating itself to RAM on
|
||||
startup automatically => "FLASH version"
|
||||
|
||||
2. as a RAM version which will not load from flash automatically as it needs a
|
||||
prestage bootloader ("chainloading") & is running only from the RAM address it
|
||||
is linked to => "RAM version"
|
||||
|
||||
This version may be very helpful when installing u-boot for the first time
|
||||
since it can be used to make available s. th. like a "bootstrap
|
||||
mechanism".
|
||||
|
||||
|
||||
How to build the different images:
|
||||
|
||||
------------------------------
|
||||
Flash version
|
||||
------------------------------
|
||||
|
||||
Compile u-boot
|
||||
|
||||
in dir ./u-boot-x-x-x/
|
||||
|
||||
please first check:
|
||||
|
||||
in ./include/configs/cobra5272.h
|
||||
|
||||
CONFIG_MONITOR_IS_IN_RAM has to be undefined, e. g. as follows:
|
||||
|
||||
#if 0
|
||||
#define CONFIG_MONITOR_IS_IN_RAM
|
||||
/* define if monitor is started from a pre-loader */
|
||||
#endif
|
||||
|
||||
=> u-boot as single bootloader starting from flash
|
||||
|
||||
|
||||
in board/cobra5272/config.mk TEXT_BASE should be
|
||||
|
||||
TEXT_BASE = 0xffe00000
|
||||
|
||||
=> linking address for u-boot as single bootloader stored in flash
|
||||
|
||||
then:
|
||||
|
||||
host> make cobra5272_config
|
||||
rm -f include/config.h include/config.mk
|
||||
Configuring for cobra5272 board...
|
||||
host> make
|
||||
[...]
|
||||
|
||||
host> cp u-boot.bin /tftpboot/u-boot_flash.bin
|
||||
|
||||
|
||||
------------------------------
|
||||
RAM version
|
||||
------------------------------
|
||||
|
||||
in dir ./u-boot-x-x-x/
|
||||
|
||||
host> make distclean
|
||||
|
||||
please modify the settings:
|
||||
|
||||
in ./include/configs/cobra5272.h
|
||||
|
||||
CONFIG_MONITOR_IS_IN_RAM now has to be defined, e. g. as follows:
|
||||
|
||||
#if 1
|
||||
#define CONFIG_MONITOR_IS_IN_RAM
|
||||
/*define if monitor is started from a pre-loader */
|
||||
#endif
|
||||
|
||||
=> u-boot as RAM version, chainloaded by another bootloader or using bdm cable
|
||||
|
||||
|
||||
in board/cobra5272/config.mk TEXT_BASE should be
|
||||
|
||||
TEXT_BASE = 0x00020000
|
||||
|
||||
=> target linking address for RAM
|
||||
|
||||
|
||||
then:
|
||||
|
||||
host> make cobra5272_config
|
||||
rm -f include/config.h include/config.mk
|
||||
Configuring for cobra5272 board...
|
||||
host> make
|
||||
[...]
|
||||
|
||||
host> cp u-boot.bin /tftpboot/u-boot_ram.bin
|
||||
|
||||
|
||||

|
||||
HINT
|
||||
----
|
||||
|
||||
If the m68k-elf-toolchain & the m68k-bdm-gdb is installed you can run the RAM
|
||||
version by typing (in dir ./u-boot-x-x-x/)
|
||||
"board/cobra5272/bdm/load-cobra_uboot" ,
|
||||
in ./u-boot-x-x-x/ the RAM version u-boot (elf format) has to be available.
