I can find this post of hippo at link : http://hi.baidu.com/61led/blog/item/bf58210aa9a2443ae824887a.html 

 i used uclinux-dist-20070130 and file pạtch uClinux-dist-20070130-nios2-02.diff.gz  followed this instruction in above link  * when i selected default setting in make menuconfig, run "make romfs", "make", "make linux image", the zimage build successful. But i saw the folder of romfs/bin have no file. I can't understand which step is wrong  When i download and boot, the kernel can't boot and get this error   Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block   *when i select microwin in menuconfig, and "make romfs" get this error:  cp:cannot stat `nano-X' : No such file or directory  "make" get this error: No rule to make target `-libjpeg', needed by 'uClinux-dist/user/microwin/src/bin/nano-X  The folder user/microwin/src/bin have 1 file "convbdf", no more another file

I don't have the solution to your problem, but if you make a mistake while modifying some files in the uClinux-dist folder and then get an error. The best solution is to remove this folder then take the original one from the 20070130.tar . Copy it into your nios2-linux folder and then do $ git pull in the copied folder. 

The nios2-linux folder must be under home/yourname/ otherwise the git update can fail. Don't forget to create folder backup ! I hope it will help you !:)
