I am using  Lauterbauk ARM In Circuit Debugger.
I have done SDRAM initializations in .cmm (batch file) of debugger and configured SDRAM address in make menuconfig.
I am able to download the image in to SDRAM mapped address but unable boot from it.
any suggestions on this. Thanks.

How do you get the image into the SDRAM? With a debugger?

However, barebox can start from SDRAM in which case it just skips
the SDRAM initialization and depending on the board some more lowlevel
init steps. Just copy the image somewhere into SDRAM and jump into
