if the BF518F-EZBRD has 64 megs, why would you want to change it ?  if you need to control memory used by Linux, then use a standard method like the mem= kernel command line.

Hi,Mike,

 

       because we are want to develop a new board,the SDRAM we use is 32 megs,so I don't know which file should be modified  so that the u-boot will run on my own board,thank you!
