Again, which CPU are you using? How is the SDRAM connected (DIMM or onboard). I suggest you check your SDRAM controller setup again. > Here I am trying to use backtrace to debug but system is waiting at > folloing console o/p. > > [r...@u-boot]$ cp ../../11dec_rec/u-boot/backtrace . > [r...@u-boot]$backtrace System.map 0xdffeb000 > Reading symbols from System.map > Using Address Offset 0xdffeb000 This link might help: http://www.denx.de/wiki/DULG/DebuggingUBoot Especially chapter 10.1.2.
