No, you can't. That part must be done while you run from flash. Actually, this is done in cpu/arm926ejs/at91/lowlevel_init.S, in the table SMRDATA1. So, with the current code base, you can't autodetect ram size on the atmel 926x. I have the same problem, as I have boards that ship as either 64M or 128M. I'd configure for 128M and look for aliases, reconfiguring for 64M if needed. This can be done in lowlevel_init.S or by setting up a temporary C environment with sp in static RAM and doing it in C. In both cases, this doesn't fit the current code base and some refactoring would be needed to go mainline. /alessandro _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
