The question about the relocate_code on u-boot for MPC8360?

Hi, Friends,


I am debuging the u-boot on freescale MPC8360, the version of u-boot is 1.2.0, the
code on flash is OK,but the code from FLASH to DDR is broken, that is, after the
relocate_code function, the u-boot start again. I tested the DDR on u-boot, it's
OK. I was wondering that hot to deal with this problem? follow is the COM output
from u-boot. Thanks.

Why did you say the DDR is OK? This sympton is most probably due to your DDR memory issue, pls check the CS on it, and see if it continusly reset or not. - Denny
