The uncompressed kernel image is made from 'Image' inside arch/arm/boot folder using the mkimage tool. What should be the entry point and load address for the uncompressed kernel image ? The physical address of my RAM is 0x30000000 and the zImage is loaded to the address 0x30008000. thanks & regardsGIGIN _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
