Your "Link address offset for booting" is too high. 0x02000000 + 0x01000000 = 0x03000000.

That address is where the zImage gets loaded, then it gets decompressed to offset 0. So size of your RAM - a bit more than the size of your image should be good. i.e. 0x01000000 - 0x400000 (4MiB) = 0xC00000 should work as long as your image doesn't grow over 4MiB.
