[U-Boot-Users] newbie question, symbol address issue

[raymond yang]

Hello,

I use B2_config, the image created confused me.

Here is the log:

#arm-linux-gdb u-boot

(gdb) file u-boot
Load new symbol table from "/project/u-boot/u-boot"?
(y or n) y
Reading symbols from /project/u-boot/u-boot...done.
(gdb) info address _start
Symbol "_start" is at 0xc100000 in a file compiled
without debugging.
(gdb) info address reset
Symbol "reset" is at 0xc100030 in a file compiled
without debugging.
(gdb) info address cpu_init_crit
Symbol "cpu_init_crit" is at 0xc1000b0 in a file
compiled without debugging.

The address of '_start', supposed would be 0x00000000,
however it is 0xc100000, so does the
'reset'/'cpu_init_crit"/all the other symbols....


When i cp this image into the flash, and use BDI2000.
The BDI2000 looks like can't recognize the 0xc10....
address,
it always announce 'hardware breakpoints full', while
the arm-linux-gdb prompts 'invalid memory address
accessed....'

I have a little experience with the U-boot on PPC
platform, i recall _start/entry-point always be at the
0x00000000, which BDI2000 fetch it from the start
point of the flash. However i am brand newbie to the
arm platform, so i guess i might have this or that
mistake on the image creation.

Am i breaking some building rules when i create the
image?
Could any big brother give me a hand?

Really appreciated!!!

Best Regards
