charset="utf-8" The default addresses to load the kernel, fdt, initrd of AMCC boards in U-Boot v2015.10 are : "kernel_addr_r=3D1000000\0" "fdt_addr_r=3D1800000\0" "ramdisk_addr_r=3D1900000\0" The taihu is one of these boards, the ref405ep is not but we don't have much information on it and both boards have a very similar address space layout. Also, if loaded at address 0, U-Boot will partially overwrite the uImage because of a bug in get_ram_size() (U-Boot v2015.10) not restoring properly the probed RAM contents and because the exception vectors are installed in the same range. Finally, a gzipped kernel image will be uncompressed at 0x0. These are all good reasons for not mappping a kernel image at this address. Change the kernel load address to match U-Boot expectations and fix loading.
