hi,

following the hippo&#39;s buildroot, i got the zimage file.

in the other side, i have u-boot working from flash memory.

now, i am wondering if that&#39;s possible to download the zimage directly with u-boot.

Here I&#39;m talking about if I have to mkimage zImage or not.

You&#39;d better write your questions more clearly. I misunderstand so many times. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

Don&#39;t mkimage, it is already compressed.

You should not want to write the zImage to flash with u-boot, either.

Put your zImage file in /tftpboot of your tftp server, and use,

tftpboot [loadAddress] zImage

where loadAddress is (your sdram address + boot link offset( default to 0x00800000) )

Well, what I&#39;m trying to do is to program the flash with the kernel via u-boot, and since u-boot deals with the .img files so I guess I got to transform the zImage with mkimage before downloading it with tftpboot.
