File: README.COBRA5272
Author: Florian Schlote for Sentec elektronik (linux@sentec-elektronik.de)
Contents: This is the README of u-boot (Universal bootloader) for our
COBRA5272 board.
Version: v01.00
Date: Tue Mar 30 00:28:33 CEST 2004

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.
