This is on the 4GB version of isee igepv5 GEP0050-RB10 https://isee.biz/products/igep-processor-boards/igepv5-omap5432 > Just wondering what other changes you made for booting a OMAP5+ based > board with more than 2GB.

Then boot with something like this in the kernel cmdline: mem=2032M@0x80000000 mem=2048M@0x300000000 Regards, Tony -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
