tftp to flash from linux

Hello Baruch,

Yes, I already thought that this nandwrite command can be used for writing. But problem is I get the image via tftp and my RAM is to little to store it temporary. 
So I have to write it directly to flash. Can I combine this nandwrite and tftp in any way? I'm using busybox

Use the nandwrite utility from the mtd-utils package (there's also a Busybox version), and a/dev/mtdx.
