I know that u-boot provides commands to access memory but I have seen that in some cases it also properly set-up board specific HW resources included flash, SDRAM etc (I think but not really sure because i'm a newbe on this subject, that some of these initialization could be provided by updating the u-boot with the proper patches).<BR>
Our problem is that neither the fist atmel bootstrap code (AT91Bootstrap) nor the atmel (AT91SAM9261 board) u-boot patch provide initialization for that kind of SRAM.<BR>

U-Boot provides generic commands to read/write memory locations (md/mw<BR>
respectively) no matter where they physically are. Once your memory<BR>
controller is set up properly (chip select timing etc.) you can easily<BR>
access the SRAM from U-Boot shell.<BR>
