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?

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
