[U-Boot-Users] Linker ERROR

[Wolfgang Kanovsky]

Hi All,

im working on an embedded ( with AMD SC520 / i386 ) board every thing comp.
nice
but i got the following Linker Error for u-Boot.

Anyone Knows this Error and its cause?

UNDEF_SYM=`i386-linux-objdump -x lib_generic/libgeneric.a

make: *** [u-boot] Error 1



2 Question: in uboot.lds (sc520_cdp board) is the following statement

	. = 0x400000; 	                    /* Ram data segment to use */
	_i386boot_romdata_dest = ABSOLUTE(.);
	.data : AT ( LOADADDR(.rodata) + SIZEOF(.rodata) ) { *(.data) }
	_i386boot_romdata_start = LOADADDR(.data);

can anyone tell me what this statement does ? and which adress = 0x400000
this is ?

thanks

Wolfgang Kanovsky
