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?

I have a bunch of sc520 fixes from a board port I did. This one is cause by a bad linker directive file (u-boot.lds).

I believe I fixed the other sc520's also. I need to check and submit a patch.

My board has a 512k 8-bit flash - you will have to adjust the flash address in the linker file and in the 16 bit .S if your flash is larger.
