[U-Boot-Users] help on u-boot

[prabha.j at tcs.com]

Hi all,
I was able to build u-boot for my custom board. when i tried to load it 
nothing is coming. I am using TRACE32 ICE and the board is almost similar 
to MPC8260ADS. I had set the baudrate as 115200 and flowcontrol as none. 
when i give run command in TRACE32, nothing is coming  in hyperterminal.
My flash base is 0x0000 0000 so i had given this in the 
board/mpc8260ads/config.mk . I have done some changes in the 
include/configs/MPC8260ADS.h 
for my board.
Any help is appreciated.
Thanks in advance.

Use your TRACE32 to step through the start up.  Where is it breaking? 
Start digging though the source at that point to find what you have 
misconfigured ;-).

Please go back to reading the documentation.

On PowerPC systems, RAM must be mapped  at  physical  address  0,  so
obviously your memory map setup is wrong.

This is wrong, and twice so. First, you should create your own  board
config  file and not meddle with existing (and working) config files.
Second, your changes to the memory map were wrong.

Hi all,
I had created myboard directory in the board directory and copied all 
files from the board/mpc8260ads into myboard directory and did some 
changes in the config file ie include/configs/myboard.h file. And in 
Makefile and MAKEALL file i included my board details.

Since my SDRAM physical address starts from 0x300000000 i had set it 
CFG_SDRAM_BASE as 30000000. and CFG_FLASH_BASE as 0x00000000 as my flash 
base address. But in README i had seen RAM's physical address should be 0. 
what i have done is correct or not.   I am attaching my address map for 
the board Please give me some idea.
when i give mybord_config it is configured .

when i try to compile it its giving error as 

make[1]: Leaving directory `/home/batsayan/u-boot-1.1.2/lib_generic'
make -C `dirname board/tcs8260ads/libtcs8260ads.a`
make[1]: Entering directory `/home/batsayan/u-boot-1.1.2/board/tcs8260ads'
make[1]: *** No rule to make target `tcs8260ads.c', needed by `.depend'. 
Stop.
make[1]: Leaving directory `/home/batsayan/u-boot-1.1.2/board/tcs8260ads'
make: *** [board/tcs8260ads/libtcs8260ads.a] Error 2

Thanks in advance.

Change your memory map. SDRAM must be mapped at physical address 0x0000.

Note that this is explicitely mentioned in the documentation.

It is not a good idea to ignore the documentation.
