While notifying the vendor about this problem [2], I tested all U-Boot releases from GL.iNet: - they really fail to boot kernel above 4096k - they don't support lzma: "Unimplemented compression type 3" - but they boot zImage Using zImage (xz compression) the kernel is 2909k which is more than a megabyte away from the KERNEL_SIZE := 4096k limit. The gzip compressed version would be 4116k.
